UNPACKING After opening the package and removing the equipment and components, make sure that you have all the items described on the order form or packing slip. DESCRIPTION The VA201 System sets new standards in gas detection and in the measurement of environmental parameters. The VA201C System is a complete control system composed of a VA201C network controller and any of the following units: a VA201T, VA301D 2, 90DM 3 R gas analyser/transmitter, VA201R relay module(s), VASQNA annunciator panel, VA420I converter, and/or the VASQN8X multi-point sample draw gas monitor. INSTALLATION GUIDELINES Make sure to locate the monitor and sensing assemblies in an area easily accessible to a technician. Avoid any location where the monitor could be subject to vibrations. Avoid any location close to equipment emitting electromagnetic interference. Avoid any location where temperature changes occur rapidly. Verify all the requirements and existing regulations which may affect the choice of location. Select a location at the perimeter of the chiller, boiler, cooler or any other equipment that may leak. Airflow patterns must also be considered. Conduit installation must conform to local fire, building and electrical codes. For the DT Duct-Type housing, installation is recommended on a straight duct at least 3 feet (1 m) away from any curve. A cable with more than 1 pair of wires is unacceptable for communication use.

DETERMINATION OF THE NUMBER OF TRANSMITTERS The number of transmitters is determined by a unit s radius of surveillance. Using Table 1 below, the number of units can be easily evaluated.

The calibration frequency will be a function of the operating conditions, including operating under extreme temperatures, exposure to contaminants or gas concentrations greater than the lower explosive limits. A calibration inspection must be included as part of a routine maintenance to ensure proper operation of the gas detection unit. If unit span or zero cannot be adjusted, the sensor may be approaching its end-of-life or has been contaminated and must be replaced. DR0009 February 2004 6 Vulcain Alarm Inc. All rights reserved
