MINERVA Marine Panel Range

MINERVA MX is a comprehensive range of fire

controllers designed and built to BSEN ISO9001/2

and EN54. An advanced proven microprocessor

based system, MINERVA MX provides conventional

and digital addressable detection for new, refurbished

and refitted detection systems.

A wide range of detectors and ancillaries makes

MINERVA MX suitable for applications from general

cargo vessels to large passenger vessels and offshore

installation.

What should you expect of your firedetection system?In broad terms: cost effective reliability and flexibility.

In today's vessels under today's conditions you should

also be looking for ease of operation, flexible

programming, precise fire source pin-pointing and the

kind of circuitry and sensitivity which ensures rapid

activation in the event of a fire.

MINERVAMX meets all theseexpectations as a matter of courseMX/T2000 is a comprehensive range of fire

controllers designed and built to BSEN ISO9001/2 by

the worlds leading fire and security company. The

MX/T2000 has been approved by all the major

marine authorities.

An advanced proven micro-processor based systemMINERVA MX provides conventional as well as

addressable detection at the price of today's

and compensations to be made for changes in

environmental conditions. In short, maximum

security whilst minimising the risk of false alarms.

Modular in design MINERVA MX provides

economical fire detection for small vessels but is also

flexible enough to implement the complex event

procedures required in larger ones. Detectors are

controlled in groups of up to 240 zones all software

configurable, so avoiding the expensive need to

hardwire each zone back to the control panel. Further

savings are made possible by harnessing the power o

the latest micro-processing technology to enable a

single loop of two-core cabling to carry both detection

and command signals.

Backwards compatibility is also achieved by using an

ancillary module which allows existing fire systems to

be updated and extended cost effectively, utilising

existing wiring where possible and with minimaldisruption. Other ancillary modules offer even greater

system flexibility: short circuit sensing isolation

ensures the MX/T2000 continues in operation, even

if a wiring fault occurs. Local sounder activation

further reduces wiring costs and switch monitoring

allows easy interface to a vessels machinery control

system.

Further flexibility and installation savings can be made

using the loop power MX/T2000 options. Loop

powered MX/T2000 panels allow sounders to be

powered from the same loop wires that carrycommunications and power to the detectors and

other ancillaries.


5/78

MINERVA MX Key Functions

Thanks to powerful software each zone can be given a tailor-made

response text message to help locate the source of a fire. Software

configuration and reconfiguration can be carried out on site, with

minimum disruption and the avoidance of system down time. Correct

execution of the software is ensured by twin micro-processors that

perform watchdog functions on each other.

MINERVA MX sounders can be set for either continuous, pulse, or a

combination of two tones via the system software.

To aid the rapid location of fire, remote repeater panels or geographical

mimics can be connected to the controllers for greater monitoring

convenience, as can visual display units.

The displayed temperature and smoke density reading allows the

operator to quickly visualise the situation and select the appropriate

procedures to be implemented.

For management information, a printer can also be connected to the

MX/T2000 providing a hard copy of events. MINERVA MX has the

capacity to store up to 1000 events in its memory. Finally a weekly test

reminder facility can be built in, while a walk-test facility allows truly

cost-effective systems checking by a single operative.

811PH Multi-Sensor Smoke and Heat Detectors

General

The 800 Series detectors are supplied in an extremely robust andreliable fully sealed construction, which has undergone stringentenvironmental type testing. All electrical contacts are moulded into theplastic to eliminate any movement.

The detectors are constructed from hardwearing Fire Resistant FR110Bayblend. The multi-sensor detectors are environmentally friendly.

They use no radioactive parts and can be returned to the factory forrecycling at the end of their life.All 800 Series detectors are supplied with integral dust covers as partof the packaging. Dust covers are retained throughout installation andremoved at commissioning time.

Installation & Service Features

The 800 Series MX VIRTUAL detectors include a host of installationand service features which are provided to reduce installation andservice costs and reduce repair times.

. Standard bases with multiple mounting options speed and simplifyinstallation

. Unique park position for commissioning and service procedures

. Detector Addressing programmed from the MX SERVICE Tool or

MX Panel. Address flag fixed to the base to prevent mix ups during service. Compatible with Tyco 600 and 900 Series bases for easy

upgrade. Panel Auto-Config and Self learn functions supported by the

detectors. Full range of remote installation and service tools. Dirty Detector Read-out can be viewed on the MX SERVICE tool or

panel

Detection Modes

All 800 Series detectors communicate to the MX detection panelusing the fast reliable MX DIGITAL loop protocol. This allows eachdetector to operate in one or two of several detection modes, thusallowing it to be easily optimised to the risk.To meet detection applications with multiple risks the 811PH and811CH detectors allow two detection modes to operatesimultaneously.

Virtual Detectors

The use of virtual detection means that installations can change thedetection mode without any physical change, taking place. Not onlycan the detection be changed at the time of installation andcommissioning but also during the life of the vessel as vessel usagechanges.Some MX detection panels even allow the detection mode to bechanged at different times of the day or automatically as occupancyand activity in the space changes.As well as providing great flexibility, using only two detector modelsmeans whole life costs are reduced by reducing manufacturing,stocking and service stocks. This also reduces the number of timesdetectors have to be changed during the life of the installation.

The 811CH is a state-of-the-art carbonmonoxide and heat detector which allows afull set of detection modes to be implementedin the MX detection panel to suit most fire andheat detection applications. The 811CH isparticularly well suited to accomodation areas,storage areas and applications where smokedetector positioning is difficult or wheresmoke detectors are prone to false alarm. Theintegration of heat detection into the 811CHallows the detector to operate in a widevariety of applications where combined risksmean that CO detection alone would beinsufficient.

The 811CH incorporates a reliable electro-chemical CO detection cell and highspecification low thermal mass thermistor foraccurate temperature detection. The 811CHprovides all the features of MX VIRTUALdetectors including self verification,temperature and CO level indication andunrivalled service functions.

Areas

There is a risk of fire or explosion in all areas

containing flammable substances in the form of

liquids, gases, dust or materials. Where these

combustible materials are mixed with air in sufficient

concentration they form flammable atmospheres and

the areas containing them are designated Hazardous

Areas. When a source of ignition, such as a spark is

applied in a hazardous area, an explosion could take

place.

Electrical equipment supplied for use in Hazardous

Areas must comply with requirements to ensure that

its introduction into the area does not increase the

existing risk. We have designed Intrinsically Safe (I.S.)

enclosures provide see-through lids and can accommodate barriers in the safe area.

The enclosures are impact resistant, flame retardant and dustproof to IP65.




Technical Information

To preclude the risk of an explosion, equipment in the Hazardous Area

must not be capable of causing ignition under normal operating, or

specific fault conditions. Limiting the energy which can be stored in,

and released by the electronic circuitry and cables in the Hazardous

Area is achieved by using Intrinsically Safe equipment and by placing

restrictions on the cable parameters.

Intrinsic safety is a technique for ensuring that the electrical energy and

temperature rise occurring during normal operation and during all

probable fault conditions are not able to cause ignition.

Intrinsic safety relies on limiting the voltage and current in the circuit so

that if a fault occurs the power available in the circuit is insufficient to

cause ignition.

To complete the explosion protection concept of a circuit a Safety

Barrier must be connected between the Hazardous

Area equipment and the source of power in the Safe Area. The

electrical power which may be supplied or drawn from a Safe Area (i.e.

an area with no definable hazard) is limited by using Galvanic Isolators

or Isolating I.S. Interface Units.

The main advantage of intrinsic safety over other methods of

protection is the fact that the majority of maintenance operations can

be carried out whilst the system is live.

800 Series Ancillary Equipment

An extensive range of ancillary modules has been

specifically designed for use with the MX/T2000

range of Fire Controllers.

The 800 range of ancillary modules provide the MX

Fire Controller with a wide degree of systems applica-

tion flexibility. This allows the field addressable loop

from the control panel to both receive inputs to the

system and control outputs from it.

This broad range of modules allows the scope of the

fire detection system to be significantly extendedbeyond a simple fire detector alarm sounder based

alarm system.


23/78

The command modules enable fire doors to be closed, fire dampers to be controlled, plus provide an interface to shut down HVAC and other plant

control equipment. With the high systems integrity offered on the MX Controller the command modules can also be used to control a public

address based evacuation system.

The CIM800 is a flexible addressable input-monitoring device that fits in the standard ancillary

housings.

The CIM800 provides a single input to current MX panels though this can be implemented as

two separately wired spurs (Style B) or as a loop (Style A). Both spur and loop input wiring can

be configured to monitor normally open or normally closed inputs. In addition both can be

configured to initiate an alarm or short circuit fault message in the event of a short circuit on

normally open monitoring circuits.

The DIM800 is designed to power and monitor a circuit of low voltage conventional detectors

and callpoints. The detection circuit is powered from an external 24V d.c. supply and is reset by

the MX addressable panel. The DIM800 monitors the external 24V d.c. and provides a fault

signal if it is lost. The input detection circuit can be wired as one or two spur circuits (Class B),

one loop configured circuit (Class A) or one 4 wire detection circuit.

The DIM800 is designed to be compatible with most conventional detection products.

Compatibility has been tested to date on the following products:

Compatible Thorn detectors:

M300 Series , M600 Series , S100 Series, H Series, S231F, S231F+, CP200

The RIM800 provides a single programmable relay output from the MX DIGITAL addressable

loop which can be programmed for a variety of applications including signalling fire conditions

to plant, machinery, fire doors, dampers & security systems.

The RIM800 relay coil is monitored. The RIM800 relay contact is rated for 2A @ 24V d.c. but

can be used to switch mains voltage when used with the HVR800.

CIM800 Contact Input Module

DIM800 Detector Input Module

RIM800 Relay Interface Module

The MIO800 is a general purpose interface module for use with MX TechnologyTM

fire detection

systems. It allows multiple input and output connections to be made between external

equipment and the MX Digital loop. Three inputs and four outputs are provided. Each input and

output can be programmed independantly using the MX Consys configuration tool to provide

customised functionality.

An IP55 rated D800 style housing is used as the standard enclosure with the option of a DIN-

Rail mounting kit for in-cabinet installations.

MIO800 Multi Input Output Module


24/78

The SNM800 is a remote addressable sounder circuit output device capable of switching

sounder and speaker circuits up to 2A @ 24V d.c. or provide a monitored output facility for othe

applications. These can be used in addition to the two sounder circuits provided as standard on

most MX detection panels.

The SNM800 can support sounder circuits wired as a spur (Class B Style Y) or in a loop

configuration (Class A Style Z).

The SNM800 can be configured with a RIM800 to provide a secure monitored extinguishing

release solenoid control.

The TM520 provides an output that can be activated based on a delay time. If either the key-

switch on the module is activated, or a predefined event within the control panel occurs then a

timed delay (set between 10 minutes and 2 hours 10 minutes) is started. When the delay

reaches zero the TM520 output is activated. The unit sounds an internal buzzer and shows a

red LED when the output is active, and shows a yellow LED when the timer is counting down.

To provide a warning that the delay is nearly over, the red LED and the buzzer will pulse 5

minutes before the end of the delay .The TM520 requires a separate 24V DC supply to operate. The module is not addressable and

will therefore not take an address on the loop.

The APM800 is an MX addressable power supply monitoring module which is usually used

with the PSM800 power supply module to make an addressable power supply. The APM800 i

designed to fix to studs on the top of the PSM800.

The APM800 monitors the PSM800 for mains failure, earth fault, battery charger fault and

battery fault. It can reset the PSM800 resettable 24Vd.c. output and initiate a battery test which

then reports battery voltage and current to the controller.

The SB520 enables the SNM800 to drive sounder circuits with higher currents whilst

maintaining the reverse polarity integrity line monitoring.

The MIM800 is a small MX addressable module designed for monitoring a single input circuit.

The MIM800 can monitor normally open or normally closed inputs and provides open and shor

circuit monitoring of the line.

The MIM800 is designed for fitting in small devices such as flow switches, special detection

devices and explosion proof callpoints. A variant of the MIM800 is used in all callpoints and

pullstations.

The HVR800 is a non-addressable device which allows a low current mains rated relay

to switch up to 10A. Alternatively a low voltage drive signal such as that provided by the

RIM800 or 80 way mimic can be used to switch the integral mains relay.

GAS MONITOR PLUS


30/78

Gasmonitor Plus

Fixed systems for gas and fire monitoring


31/78

Gasmonitor Plus is our flexible microprocessor controlled

system designed with a modular approach, so you get exactly

what you want.

Used throughout the world, both on and offshore, Gasmonitor Plus

provides the cost effective solution to your system requirements.

Gasmonitor Plus, the gas and fire control system you can trust.

Simple to use

Gasmonitor Plus offers flexibility whilst still providing

simple operation.All the day to day functions

are accessible via push buttons on the

front panel.

As well as a rolling display, indicating the channel

currently monitored, each channel has a bar graph

display. This unique bar graph format is ranged

to indicate readings below the first alarm setting,

providing an instantaneous representation

of the gas concentration on every detector.

Common alarm LEDs on the display card and

individual alarms on the panel only light when a

hazard or fault is detected. This meansthe whole

rack status can be checked at a glance.

Ground breaking design

Gasmonitor Plus is a microprocessor based expandable

control system, which can be multiplied to offer

unlimited channels and outputs.

Its modular construction provides ultimate

customisation capacity with minimal wiring.

Gasmonitor Plus has industry standard analogue

outputs, and the mechanical design is based on 19

Eurorack. This means that the Gasmonitor Plus

will integrate fully with existing rack

mounted protection systems on site.

The alochrome finish and rack screening plates

ensure that the Gasmonitor Plus is impervious to

radio frequency interferance.

Flexible architecture

Each channel has three levels of alarm as wellas a dedicated analogue output, set as 4-20

mA as standard.

Optional relay modules can interface to the panel to

provide up to a total of 84 output relays per

rack. Sixteen of these relays can be configured/

voted from a combination of the three levels of alarm

per channel.

The RS232 digital interface provides connectivity

with PC for configuration, monitoring and datalog

upload. Each rack is uniquely addressable, making

multi-drop architectures possible. This cuts down on

configuration and monitoring cabling.

Easy maintenance

Gasmonitor Plus has been designed witheasy servicing and maintenance in mind.

Each channel is inhibited separately so that

plant safety is not compromised during

maintenance checks.

Routine calibration can be achieved from the front

panel. The one man calibration feature reduces the

service overhead by half.

One universal gas card architecture controls all gas

detectors. This reduces the spares holding

required for Gasmonitor Plus maintenance. Each

control card is fitted with its owndedicated micro-controller so it can

function independently in the event of a single

WARNING

TXgard-Plus is designed for use in Zone 1 and 2 hazardous areas and

is certified EEx d IIC T6 (AEx d IIC T6 in USA). Installation must be in

accordance with the recognised standards of the appropriate authority

in the country concerned. For more information contact Crowcon.Prior to carrying out any work ensure local regulations and site

procedures are followed.

3.1 Location

There are no rules w hich dictate the siting and location of detectors, how ever,

considerable guidance is available from B S6959:1988 British S tandard

C ode of Practice for the Selection, Installation, U se and M aintenance of

Apparatus for the D etection and M easurem ent of C om bustible G ases. In the

U SA refer to the N ational Electrical C ode (N EC 1999). Sim ilar international

codes of practice m ay be used w here applicable. In addition certain regulatory

bodies publish specifications giving m inim um gas detection requirem ents for

specific applications.

The detector should be m ounted w here the gas is m ost likely to be

present. The follow ing points should be noted w hen locating gas detectors:

To detect gases w hich are lighter than air e.g. am m onia, detectors should

be m ounted at high level and C row con recom m end the use of a C ollector

C one,Part No. C01051.

To detect heavier than air gases e.g. sulphur dioxide, detectors should be

m ounted at low level.

having specialist know ledge of gas dispersion, the plant processing equipm ent as

w ell as safety and engineering issues. The agreement reached on the

locations of sensors should be recorded.C row con w ould be pleased to assist

in the selection and siting of gas detectors.

3.2 Mounting

The m ounting detail of TX gard-Plus is given in D iagram 1. TXgard-Plus should

be installed at the designated location w ith the detector pointing dow n. This

ensures that dust or water w ill not collect on the sinter and stop gas entering

the detector.

3.3 Cabling Requirement

C abling to TXgard-Plus m ust be in accordance w ith the recognised

standards of the approp riate authority in the country concerned and m eet the

electrical requirem ents of the detector. C row con recom m end the use of steel

w ire arm oured (SW A) cable and suitable exp losion proof glands m ust be

used. Alternative cabling techniques, such as steel cond uit, m ay b e

acceptable provided approp riate standards are m et.

TXgard-Plus requires a dc supply of 10-30 V at up to 100 m A.

Ensure the m inim um dc supply of 10 V is ob served at the detector, taking into

account the voltage drop due to cable resistance.

For exam ple, a nom inal dc supply at the control panel of 24 V has a

guaranteed m inim um supp ly of 18V. The m axim um voltage d rop

allow ed is therefore 8V. TXgard-Plus can dem and up to 100 m A and so the

m axim um loop resistance allow ed is 80 O hm s. A 1.0 m m 2 cable w ill typically

allow cable runs up to 2000 m . Table 4 show s m axim um cable distances

given typical cable param eters.

Acceptable cross sectional area of cable is 0.5 to 1.5 m m 2. Table 4 provides

guidance only, actual cable param eters for each application should be used to

calculate m axim um cable distances.

3.4 Electrical Connections (4-20mA use)

All connections are m ade via the term inal board m ounted in the base of thejunction box (see D iagram 2). The 3 w ires from the 96H D are colour coded

and should be term inated in the corresponding colour coded term inal

(term inals 4, 5 & 6). Term inals 1 (0 V dc), 2 (10-30 Vdc) and 3 (4-20m A signal)

are connected to the control equipm ent. TXgard-Plus is factory set as a 4-

20 m A source d evice unless specified otherw ise w hen ordering (see Section

2 to change configuration). D iagram 3 sum m arises the electrical

connections.

Note: The junct ion box and cable armour must b e earthed at the

detector and control panel to l imit the effect of radio frequency

interference and to maintain electrical safety.

1.1 Product overview

Flamgard Plus is a flameproof flammable gas detector

suitable for use in zone 1 or 2 hazardous areas. It is designed to detect

flammable gas, present in ambient air, at concentrations not

exceeding the Lower Explosive Limit (LEL) of the target gas for which

it is calibrated. A local display and magnetically operated switches

allow non-intrusive one-man calibration without a hot work permit.

Powered by 24 V dc (nominally) Flamgard-Plus provides a 4-20 mA

signal (sink or source) proportional to the gas concentration and can

also be fitted with optional alarm and fault relays. For a list of

flammable gases that can be detected, please contact Crowcon.

1.2 Product descriptionFlam gard Plus com prises four parts; 96H D sensor housing, junction box, am plifier and

term inal board. D iagram 1 details Flam gard Plus. The overall assem bly is certified EEx d

IIC T6 in Europe and C lass 1 , Zones 1& 2 AEx d IIC T6 in the U SA.

The 96H D sensor housing is a m odular stainless steel assem bly that

dism antles to allow plug-in pellistor sensors to be replaced easily (see D iagram 4). The

assem bly screw s into an M 20 entry on the junction box.

The junction box is m anufactured from m arine grade alloy and is supplied w ith

2 x M 20 (1/2N PT for U SA) cable entries for custom er use. Alternative cable entries are

available from C row con.

The am plifier plugs into the term inal board, and is held in place b y tw o captive

screw s. The am plifier provides pow er to the pellistor sensor, local display and controls,

and a 4-20 m A signal proportional to the gas concentration for connection to a control

panel. To rem ove, turn screw s anti-clockw ise and use them to pull am plifier out of the

enclosure.

WARNING

Flamgard Plus is designed for use in Zone 1 and 2 hazardous areas and

is certified EEx d IIC T6 (AEx d IIC T6 in USA). Installation must be in

accordance with the recognised standards of the appropriate authority

in the country concerned. For more information contact Crowcon.

Prior to carrying out any work ensure local regulations and site


3.1 Location

There are no rules w hich dictate the siting and location of detectors, how ever,

considerable guidance is available from BS6959:1988 British S tandard

C ode of Practice for the Selection, Installation, U se and M aintenance of

Apparatus for the D etection and M easurem ent of C om bustible G ases. In the

U SA refer to the N ational Electrical C ode (N EC 1999). Sim ilar international

codes of practice m ay be used w here applicable. In addition certain regulatory

bodies publish specifications giving m inim um gas detection requirem ents for

specific applications.

The detector should be m ounted w here the gas is m ost likely to b e

present. The follow ing points should be noted w hen locating flam m able gas

detectors:

To detect gases w hich are lighter than air e.g. m ethane, detectors should

be m ounted at high level and C row con recom m end the use of a C ollector

C one,Part No. C01051.

To detect heavier than air gases e.g. butane, detectors should be m ounted

at low level.

W hen locating detectors consider the possible dam age caused by natural

events e.g. rain or flooding. For detectors m ounted outdoors C row con

recom m end the use of a W eatherproof C ap,Part No. C01442.

C onsider ease of access for functional testing and servicing.

C onsider how the escaping gas m ay behave due to natural or forced air

currents. M ount detectors in ventilation ducts if appropriate.

C onsider the process conditions. B utane is norm ally heavier than air, but if

released from a process line w hich is at an elevated tem perature and/or

under pressure the gas m ay rise rather than fall.

The placem ent of detectors should be determ ined follow ing advice of

experts having specialist know ledge of gas dispersion, the plant processing

equipm ent as w ell as safety and engineering issues.The agreement reached

on the locations of sensors should be recorded. C row con would be

pleased to assist in the selection and siting of gas detectors.

3.2 MountingThe m ounting detail of Flam gard P lus is given in D iagram 1. Flam gard P lus

should be installed at the designated location w ith the detector pointing dow n.This ensures that dust or w ater w ill not collect on the sinter and stop gas

entering the detector.

3.3 Cabling RequirementC abling to Flam gard P lus m ust be in accordance w ith the recognised

standards of the approp riate authority in the country concerned and m eet the

electrical requirem ents of the detector. C row con recom m end the use of steel

w ire arm oured (SW A) cab le and suitable explosion proof glands m ust be

used. Alternative cabling techniques, such as steel cond uit, m ay be

acceptable p rovided appropriate standards are m et.

Flam gard P lus requires a dc supply of 10-30 V at up to 210 m A.

Ensure the m inim um dc supply of 10 V is observed at the detector, taking into

account the voltage drop due to cable resistance.

For exam ple, a nom inal dc supply at the control panel of 24 V has aguaranteed m inim um supp ly of 18V. The m axim um voltage drop

allow ed is therefore 8V. Flam gard P lus can dem and up to 210 m A and so the

3.4 Electrical connect ions (4-20mA use)

All connections are m ade via the term inal board m ounted in the base of the

junction box (see D iagram 2). The 3 w ires from the 96H D are colour coded

and should be term inated in the corresponding colour coded term inal

(term inals 4,5 & 6). Term inals 1 (0 Vdc), 2 (10-30 Vdc) and 3 (4-20m A signal)

are connected to the control equipm ent. Flam gard Plus is factory set as a

4-20 m A source device unless specified otherw ise w hen ordering (see S ection

2 to change configuration). D iagram 3 sum m arises the electrical connections.

Note: The junction box and cable armour m ust be earthed at the

detector and control panel to limit the effect of radio frequency

interferenc e and to maintain electrical safety.

All electrical connections to the optional relays are m ade via the 6-way

term inal block on the term inal board in the base of the junction box (see

D iagram 2). The relay contacts are rated 1 A @ 30 Vdc.
