CHAPTER 1

INTRODUCTION

1. INTRODUCTION

The Extinguishant Release Module (ERM) forms an integral part of an approved fire detectioncontrol panel. Its microprocessor control contributes to the distributed intelligence. The designincludes safety features which reduce the chances of an accidental discharge. It is compatiblewith all forms of extinguishant formats.

The ERM has been designed, manufactured and tested under the stringent requirements of BritishStandard (BS) 5750 Part 1.

The ERM has been designed to meet the following standards:

BS 7273 Parts 1 and 2.

BS 6226.

BS 5306 Parts 0 and 4.

EN 55022.

EN 54 Current Draft.

Pre EN BCYG-2A Final Draft.

1.2 EXTINGUISHANT RELEASE MODULE

The ERM consists of two components: the display module and the printed circuit board (PCB).

The display module has; a polycarbonate membrane fascia, a status indicator pcb, a manualextinguishant release unit, an AUTOMATIC/MANUAL keyswitch and LEDs complete withslider inserts for the appropriate text.

The LEDs are labelled via four text inserts supplied with each unit:


DESIGNATION DESIGNATION DESIGNATION DESIGNATION

DISCHARGE DISCHARGE DISCHARGE DISCHARGE

2nd STAGE 2nd STAGE 2nd STAGE 2nd STAGE

DISABLED DISABLED DISABLED DISABLED

ABORT ABORT

HOLD HOLD

AUTO/MANUAL AUTO/MANUAL AUTO/MANUAL AUTO/MANUAL

MANUAL ONLY MANUAL ONLY MANUAL ONLY MANUAL ONLY

The text inserts can be typed on an individual basis therefore enabling multi-language capability.

In addition text can be allocated to identify the protected area.

The AUTOMATIC/MANUAL ONLY keyswitch allows the operator to select the desired modeof operation. The keyswitch is spring-biased, non-removable in the left and right hand operatedpositions. It is only removable in the central parked position. This configuration allows themode of operation to be switched from automatic to manual and to be controlled from numeroussources such as the main ERM, status indicators and door interlocks.

The pcb accepts the following inputs from the main fire control panel: 1st stage, 2nd stagesilence and reset. This information is transformed using the on-board processor. The pcbincorporates numerous inputs and outputs which depending upon their importance, aremonitored.

The manual extinguishant units are constructed of yellow thermoplastic with a micro-switchwhich is held operated by the edge of the glass. This has increased protection against accidentaloperation by means of a hinged transparent polycarbonate cover.

The ERM is controlled via the basic commands of the main fire control panel which enables thesilencing of the audible alarms and resetting of alarm condition.

It is of robust construction, precise with information and simple to use. The 2 wire datatransmission to status indicators has been designed to save cable on installation.


1.3 SYSTEM OVERVIEW

The range of fire detection and extinguishant control panel will be configured utilising threemajor components housed within the same enclosure. This will enable systems to be engineeredto meet specific requirements on an individual basis or standard configuration panels to meet thegeneral requirements of the market. The major components are: fire detection control panel,ERM and power supply.

A system overview is shown in Figure 1-1.

1.3.1 Fire Detection Control Panel

The detection system should meet the minimum requirements of BS 5839 Part 1 1988, unlessincreased detection is recommended by BS 6266 and/or BS 7273. A choice of detectionmediums are available to suit the requirements of the protected risk, these are conventional andanalogue addressable.

The current range of control panels, i.e. Sirius Antares and Procyon, have been accredited by theLoss Prevention Council Certification Board as meeting the requirements of BS 5839 Part 41988. The Vega control panel may also be used to interface with the ERM unit refer to Appendix4.2.

1.3.3 Power Supply

The full range of power supplies offered have been accredited by the Loss Prevention CouncilCertification Board as meeting the requirements of BS 5839 Part 4 1988.

The Sirius range of control panels have an integral power supply which after reviewing theloading of the system may be capable of supplying the required load for the ERM.


The Antares and Procyon control panels will have to be powered by the standard Regulus powersupplies in the 4 or 10 Amp formats depending upon the system load requirements.1.3.4 Status Indicators

A status indicator can be supplied as an optional addition to ERM, these are of the sameconstruction as the ERM display modules, but do not include the ERM main pcb.

There are three types of status indicator:

1. LEDs only

2. LEDs and AUTOMATIC/MANUAL keyswitch.

3. LEDs, AUTOMATIC/MANUAL keyswitch and manual extinguishant release breakglass.

All three types can be supplied boxed or unboxed.

A maximum of five status indicators can be connected to the ERM. The status indicator boardconnects to the main ERM via a two-core cable. The information is transferred in an RS422format which is decoded via the on-board processor PIC16C55 to illuminate the relevantindications.

Figure 1-1 System Overview


CHAPTER 2

TECHNICAL SPECIFICATION 2. EXTINGUISHANT RELEASE MODULE

The ERM pcb is constructed on a double-side board and uses the Motorola 68HC711E9 IC toprocess the operational and control data. The program and data space is contained wholly on themicrocontroller. Specific software is required to control the inputs and outputs of the processor. The software is written in C and compiles to the IC source code.

Correct operation of the program is monitored by the watch-dog circuit. If the program shouldfail to stimulate the watch-dog at least once every 42 ms, the processor would perform a reset,therefore restoring the correct operation.

If a fault condition occurs on either of the two sounder circuits, the release of the extinguishantwill be inhibited.

There are two distinct types of input onto the ERM board:

1. Monitored Inputs.

2.1 UNMONITORED INPUTS

All the input and output terminals will accommodate conductors of cross-sectional area between1.0 and 2.5mm.

2.1.1 Outputs

2.1.1.1 Sounder Circuit 1

This reverse monitored sounder circuit is rated at 2.5 Amp and operates in two distinct modes.

1. A pulsed mode of operation which can be configured to operate as an audible indicationof 1st stage.

2. An intermittent mode of operation which will give an audible indication of the operationof the hold switch.


2.1.1.2 Sounder Circuit 2

This reverse monitored sounder circuit is rated at 2.5 Amp and operates in two distinct modes.

1. A pulsed mode of operation to indicate that extinguishant release is imminent.

NOTE This as a different pulse frequency to sounder circuit 1.

2. A constant mode of operation to indicate that the extinguishant agent has been released.

2.1.1.3 Actuator Output

Due to the low resistance of the various types of actuators it is only possible to providemonitoring of the circuits for open circuit conditions. The circuit provides 24 V d.c in theoperated state to initiate the release of the extinguishant and the output to the actuator is rated at2 Amps.

Compatible actuators:

Control Head K62454.

Control Head K62844.

Solenoid K62422B.

Solenoid B6793-709. Note: When using this solenoid a suppression diode must be fitted.

2.1.1.4 Display/Status Indicator Output

This RS422 communication link provides a two wire connection which updates the condition ofthe status LEDs, i.e discharged, 1st stage, 2nd stage, disabled, abort, hold, auto/manual andmanual only.

2.1.1.5 24 V Output

This is a fused output rated at 1.6 Amps and is used to provide the operational power for thestatus indicators.

2.1.1.6 Fault Output

This is a common fault indication which provides a 0 V output in a fault condition which willbe connected to the main control panel.

2.1.1.7 1st and 2nd Stage Outputs

These are 0 V outputs rated at 100 mA and activate in sympathy with the 1st and 2nd stageinputs.2.1.2 Monitored Inputs


These inputs are taken externally to the control panel and therefore it is essential that the circuitsare monitored for open - and short-circuit fault conditions. The monitoring of the inputs isaccomplished by means of an end-of-line resistor.

2.1.2.1 Hold

The operation of this input, at the extinguishant release imminent stage, will stop theextinguishant release timer and activate the alarm circuit 1 in an intermittent mode. Upon releaseof the switch the extinguishant release timer will then restart.

If the switch is operated and an alarm condition does not exist the panel will respond with a faultcondition.

NOTE The hold switches must be of a non-latching type.

2.1.2.2 Abort

The operation of the input will block the release of the extinguishant by causing the panel toinitiate the disablement mode. The extinguishant can only be released by resetting the panel andrestarting the release program.

2.1.2.3 Pressure Monitor

This input connects to a pressure switch located on the extinguishant cylinders and will monitorfor leakages of the extinguishant that will impair the effectiveness of the extinguishant agent.

2.1.2.4 Discharged

This circuit connects to a flow switch usually connected to the manifold of the release pipe andgives and actual confirmation that the extinguishant has been released. Operation of this inputwill also cause the sounder circuit 2 to operate in a constant mode and the released LED on thedisplay module will illuminate.

2.1.2.5 Manual Release

This circuit is in parallel from the manual release located on the display unit. Activation of thiscircuit will cause the release timer to activate and unless inhibited will initiate a release.

2.1.2.6 Automatic/Manual Key Switch

This circuit selects the desired mode of operation from automatic and manual release of theextinguishant to manual only release. The state of change will be reflected by the LEDindications located on the display and associated status indications.

2.1.3 Unmonitored Inputs


These inputs are for internal use within the control panel and therefore monitoring is notrequired.

2.1.3.1 Sounder Circuit 1 and 2

These inputs require a 0 V input to externally operate the sounder circuits.

NOTE The sounder circuits will operate in a continuous mode if activated fromtheseinputs.

2.1.3.2 Zone 1 and 2

These inputs require a 0 V input from the detection control panel from the coincidence (doubleknock crossed zoned) detection circuits to activate the 1st and 2nd stages of the unit.

These inputs are scanned by the ERM software to protect against transients and after verificationthe input will be processed.

2.1.1.3 Disabled

This input requires a 0 V to block the release of the extinguishant agent, this input can beactivated from the lock of mechanism on the extinguishant cylinders or a micro-switch locatedon the control panel door.

2.1.3.4 Silence Alarms

This input requires a 0 V input from the fire detection control panel to silence the sounder circuit2 (extinguishant release imminent).

2.1.3.5 Reset

This input requires a 0 V input from the fire detection control panel to reset the ERM unit.

2.1.3.6 Supply

These terminals accept a 24 V supply to provide the required power for the unit. The operatingvoltage range is 21 to 28 V d.c.


2.2 STATUS INDICATOR

Inputs

Receive data input terminals RX + and RX-.

CHAPTER 3

INSTALLATION AND COMMISSIONING 3.1 GENERAL

The installation of the extinguishant system control panel will vary depending upon whichsystem configuration has been chosen. In all cases, the guide lines given in this chapterMUST be adhered to as a minimum.

3.1.1 Standards

Make sure that the fire detection and extinguishant system complies with the current editionsof the :

1. IEE Wiring Regulations.

2. The British Standard for fire detection and alarm systems for buildings.

3. Hong Kong Fire Services Department.

3.1.2 Static Sensitive Devices

A static sensitive device is any transistor or integrated circuit which may be permanentlydamaged due to electrostatic potentials and is generally encountered during routine handling,repair and transportation.

Static electricity is produced almost every time plastics or textiles are stroked or separated.

Static charges are collected on adjacent conductors and are delivered in the form of sparkspassing between conductors through insulating space or material. The sweat layer on thehuman skin is of a sufficient medium to store induced static charges and deliver them to anyreceptive conductor such as a component or pcb.

Static discharges can be reduced by adhering to the following guide lines:

1. Always use conductive or anti-static containers for transportation or storage.

2. Wear an earth wrist strap when handling static sensitive devices, make sure that agood earth connection is maintained.

3. Never subject static sensitive devices to a sliding movement over any surface andavoid any direct contact with the pins.


4. Avoid placing static sensitive devices on plastic or vinyl surfaces.

5. Minimise the handling of static sensitive devices and pcbs.

All static sensitive devices are marked accordingly, but it is good engineering practice to treatall components and pcbs with the same degree of protection.

3.2 INSTALLATION

See Figures 3.2.1, 3.2.2 and 3.2.3.

IT IS RECOMMENDED: to remove the chassis, doors and back plates from the fire controlpanel to avoid damage during installation.

All external cables are to be securely glanded via the 20 mm preformed knock out located in thetop of the control panel enclosure.

When the cables have been installed, clean the interior of the control panel enclosure making surethat all masonry, debris and drilling swarf has been removed.

3.2.1 Conventional Control Panel Interface

The Sirius range of control panels have been enhanced to provide an effective interface with theERM. The Sirius provides local output controls for silence alarms, reset and evacuate with aninput for the fault monitoring from the ERM.

The interconnection between a 2-zone Sirius and 1 ERM is detailed in Table 3.1.

3.2.2 Addressable Control Panel Interface

The Antares and Procyon range of control panels utilise the special 489/490 outputs pcb toprovide the interface with the ERM. The special 489/490 output pcb provides the interface forup to nine ERMs to one addressable control panel.

The interconnection between an addressable control panel and one ERM is detailed in Table 3.2.

3.2.2.1 Detection - Inside the Protected Area

This is a very basic method of co-incidence detection using default outputs to achieve co-incidence from any of the detectors in the protected area. Upon the first detector operating thealarm repeat output terminal will drive low (0 V) into Zone 1 of the ERM and using the specialoutput on the 489/490 pcb "more than 1 detector operated" driving into Zone 2 of the ERM. Therefore the co-incidence detection is achieved without any programming of the control panel.


3.2.2.2 Multiple ERMs and/or Detection - Peripheral Areas

The special output pcb set 489/490 located in the addressable control panel can provide sixteensets of double-knock outputs. Input devices are assigned to a set of outputs via the programmingof the control panel.

A typical example of how the co-incidence is achieved is given below:

1st set of outputs All the input devices assigned to the single-knock outputterminal x single-knock will be assigned to the associated double-knock output.terminal x double-knock In the event of an input device operating, the single-knock output

will drive low (0 V). Upon a second device assigned to the outputset operating the double-knock output will drive low (0 V).

The above example will provide co-incidence detection from any two devices within theprotected area and will have the capability to accommodate detection in peripheral areas whichwill not vote towards the discharge of the extinguishant.

3.2.3 Addressable Loop Interface

Using the addressable input and output modules, an extinguishant interface can be configuredremote from the control panel. This configuration utilises the programmable loop output toachieve the co-incidence. A typical example of the interface is shown in Figure 3.2.3.1.

All equipment should be installed in the same enclosure, which should have the door fabricatedto accept the ERM display, complete with manual release break glass and auto/manual keyswitchif required, and an enable keyswitch which will give access to the momentary switches forsilence alarms reset.

The addressable interface will vary dependent upon which protocol is used, but the basicrequirements are:-

1. Addressable output - for 1st knock.

2. Addressable output - for 2nd knock.

3. Addressable input - discharged (alarm signal at main control panel).

4. Addressable input - fault (fault signal at main control panel).

The co-incidence is achieved as follows: Half of the detection devices located in the protectedarea will be assigned to the 1st knock output device and the other half assigned to the 2nd knockoutput device. The ERM will require local controls via an enable keyswitch to enable silencealarms and reset of the system. A local 24 V d.c power supply is required for the ERM and mayneed to power the addressable input and output devices.

IT IS RECOMMENDED: that a local LED indicator is used and a remote indicator located on


the main control panel fascia.

3.3 COMMISSIONING

(a) Check that all external wiring is correctly identified and using a multimeter check thatthe cables are free from fault condition, i.e earth, open-and short-circuits.

(b) Re-install the inner chassis into the control panel enclosure.

(c) Connect the external wiring into their respective terminals and if applicable replacingany end-of-line resistors to the last device on the circuit.

(d) Prior to the initial power up of the control panel, carry out the following preliminarychecks;

(i) Check for any visible signs of damage which may been caused duringinstallation.

(ii) verify that all installation instructions have been adhered to.

(iii) Physically check that the main pcb is secure in its mounting.

(iv) Check that the ribbon cable is secure and correctly connected.

(v) Check that all cable terminations are secured.

(e) All damage and faults must be rectified before proceeding.

(f) Prior to connecting any a.c mains supply to the power supply unit, use a multimeter tomake sure that the supply is not present and take precautionary steps to avoidaccidental application of the a.c mains supply.

(g) Connect the a.c. mains supply cables into the mains input terminals and remove thelocal on board mains fuse.

3.3.1 Preliminary Cautions

(a) Prior to the initial power up, make sure that all end-of-line monitoring resistors havebeen installed at the end of each applicable circuit and that the actuator has NOT beenconnected to the cylinders or connect dummy loads across the actuator circuits.

(b) Make sure that adequate precautions are taken when connecting the a.c mains supplyto the power supply unit.

(c) Make sure that all relevant personnel are aware of the commissioning procedures and that permission has been granted to sound the audible alarms and/or shut-down plantor electrical supplies.


3.3.2 Initial Power Up

The system specification will determine the functional operation of the installation which willbe achievable via the on-board link selects and control switches, refer to Chapter 4.

Upon initial power up of the associated control panel the ERM will display a processor faultby illuminating LED D3, located on the main pcb and will transmit a fault output to thecontrol panel. The processor fault can be reset by operating SW1, located on the main pcb.

As a built in safety feature, the ERM will always power up into the "manual only" mode.

If any faults are on the external circuits they can be easily diagnosed as they are displayed onthe amber seven segment display located on the main pcb, for additional information refer toChapters 4 and 5.2.

Once the ERM is in the quiescent mode, performance checks on the system configuration canbe made.

Table 3.4, gives a brief summary of the performance chart. The operation of the ERM isdependent upon the link selects and the input circuits which are utilised.

4.2 OPERATING INSTRUCTIONS

The controls which govern the ERM are located on the main fire panel with the exception ofthe AUTO/MANUAL keyswitch.

Main Fire Panel Control ERM Effect

SILENCE ALARMS - Will silence the sounder cct 1 only, i.e 1st stage alarmcondition.

- Silence fault buzzer generated by ERM faults.

RESET - Will reset the ERM from fault conditions.


- Will reset the ERM from 1st and 2nd stage alarmconditions.

- Will silence the sounder cct 2 when the release imminentis being terminated via a reset command.

SOUNDS ALARMS - Can generate an output to the ERM which could be usedto drive sounder cct 1 or sounder cct 2.

MAINTENANCE 5.1 ROUTINE MAINTENANCE

For routine maintenance, refer to the main fire control panel manual.

5.2 FAULT FINDING

All faults detected by the ERM will transmit 0 V signal to the fire control panel which will beindicated as a general fault condition: visually and audibly.

The ERM will give a visual indication of the fault on either the amber seven segment display orLED D3. The indications, respective designation and probable cause are given in the Table 5.1.

A-1 Extinguishing Release Module fitted to aDunford Sirius Conventional Detection Fire Control Panel


A.2 VEGA CONTROL PANEL INTERFACE TO EXTINGUISHANT RELEASE UNIT

The Vega analogue addressable control panel can be configured utilising Apollo or Hochiki ESPprotocol to enable connection to a wide range of detection devices. The panel offers the followingas a minimum standard:-

1. One detection loop with 24 zone indications. (expandable to 16 loops, 120 zones)2. Four reverse polarity monitored programmable sounder circuits.3. Four sets of volt-free change over programmable relay contacts.4. 0 volt switching inputs for external fault monitoring and remote silence \ reset functions.5. 0 volt switching outputs to silence and reset remote equipment.6. 2.5 Amp power supply unit.

The interconnection between the control panel and one ERM is detailed in table 5.2 below.

Table 5.2

The 28 Volt dc supply connection should be made direct to the integral power supply charger unitlocated within the control panel.

The Vega panels programmable relays “REL 1" and “REL 2" are used to initiate the ERM unitduring an alarm condition. These will require on site programming using the engineers softwarepackage Viper. The options available to activate a programmable panel relays are defined withinthe Viper software programme and manual.

A typical cause \ effect programme would require “REL 1" to be set to operate on a single knockcondition for the specified zone area therefore initiating 1st stage operation on the ERM. “REL2" would be programmed to operate upon the activation of two devices (double knock) withinthe same zone area initiating 2nd stage operation on the ERM unit.

The above example will provide co-incidence detection from any two devices within the sameprotected zone area. It is also possible using the Viper software to programme relays 1 and 2 toinitiate the ERM by two separate zones which may be located within the one protected area.


Figure 4-4 details the wiring diagram of a standard Vega panel connected to one ERM unit.

Figure 4-4

Multiple ERM units within one Vega control panel


To enable the Vega control panel to interface with multiple ERM units additional relay outputswill be required within the control panel enclosure. These can be supplied using the Vegamotherboard (44782-K091) installed with either the 8 way relay output card (44782-K092) or16 way open collector output card (44782-K095) The additional programmable panel outputs canthen be internally wired and configured to operate the relevant ERM unit through the panelprogramming.

A suitable power supply must also be installed within the system to accommodate the increasein current requirements. These are offered as standard on a factory prepared control panel usingmultiple ERM units.
