UNPACKINGAfter opening the package and removing the equipment and components, makesure that you have all the items described on the order form or packing slip.

DESCRIPTIONThe VA201 System sets new standards in gas detection and in the measurement ofenvironmental parameters. The VA201C System is a complete control system com-posed of a VA201C network controller and any of the following units: a VA201T,VA301D2, 90DM3R gas analyser/transmitter, VA201R relay module(s), VASQNAannunciator panel, VA420I converter, and/or the VASQN8X multi-point sampledraw gas monitor.

INSTALLATION GUIDELINESMake sure to locate the monitor and sensing assemblies in an area easilyaccessible to a technician.

Avoid any location where the monitor could be subject to vibrations.

Avoid any location close to equipment emitting electromagnetic interfer-ence.

Avoid any location where temperature changes occur rapidly.

Verify all the requirements and existing regulations which may affect thechoice of location.

Select a location at the perimeter of the chiller, boiler, cooler or any otherequipment that may leak. Airflow patterns must also be considered.

Conduit installation must conform to local fire, building and electricalcodes.

For the DT Duct-Type housing, installation is recommended on a straightduct at least 3 feet (1 m) away from any curve.

A cable with more than 1 pair of wires is unacceptable for communicationuse.

DETERMINATION OF THE NUMBER OF TRANSMITTERS

The number of transmitters is determined by a unit’s radius of surveillance. UsingTable 1 below, the number of units can be easily evaluated.

TABLE 1Radius of surveillance

PERIODIC INSPECTIONS AND CALIBRATIONThis unit requires calibration. The calibration frequency will be a function of theoperating conditions, including operating under extreme temperatures, exposureto contaminants or gas concentrations greater than the lower explosive limits. Acalibration inspection must be included as part of a routine maintenance to ensureproper operation of the gas detection unit.

If unit span or zero cannot be adjusted, the sensor may be approachingits end-of-life or has been contaminated and must be replaced.

** Local power source must be used for these applications.

WARNINGA VA201R Relay Module will increase the total number of units perchannel by 1 unit for every 2 relays. Consequently, a VA201R-8 RelayModule will increase the total number of units per channel by 4. A VA420I Module will increase the total number of units per channelby 2.

The network communication wire gauge depends on the distance between thecontroller and the last transmitter on each communication channel.

For each channel, one distinct shielded twisted pair is needed with 6 twists perfoot.

COMB Most combustibles are heavier than air, with the exception of methane, hydro-gen, ethylene and acetylene. For gases that are heavier than air, sensors shouldbe installed approximately 30 cm (1 foot) from the floor. For combustibles thatare lighter than air, sensors should be installed 30 cm (1 foot) from the ceiling,close to the potential leak source.

* May differ in certain applications. Hot NO2 from the exhaust system is lighterthan 1.58.


DETERMINATION OF NUMBER OF SYSTEMSThe number of transmitters required is determined by a unit’s operational radius of sur-veillance. Using Table 6 below, the number of units required can be easily evaluated.

PCT-1TX SINGLE-POINT SAMPLE-DRAW ALL-WEATHERHOUSING

The PCT-1TX is designed to enhance the transmitter’s use in environments need-ing Nema 4 protection or in extreme climatic conditions. The aspiration systemoffers the possibility of mainteance accessibility for a transmitter while air aspira-tion is made in out of reach areas. If a lower range of temperature operation isneeded, a heating option is available in order to stabilize the temperature insidethe unit. To assure steady aspiration flow on the pump, an optional flow surveil-lance system with strobe light is also offered.
