Instruction 2.0 QUICK START r The Gas Sensor Module has been supplied factory calibrated and ready for immediate installation and operation. An installer familiar with installation and operation of gas detection products can use this section to begin immediate use of the monitor. 2.2 Wiring Each module requires four -conductor wiring (two wires for power and two wires for the signal). See section 6.3 and Table 2.1 for wiring instructions. 2.3 Module Installation 1. Model 20X Series The module can either be installed on the end of a 3/4" conduit, or attached to a vertical surface using the mounting flange on the enclosure. Two important warnings: The installation must meet any hazard- ous environmental codes for AC/DC Elec- trical instrumentation. The sensor module enclosure mounting must be far enough away from any ver- tical surface to allow removal and re- placement of the sensor assembly which is threaded into the second 3/4" conduit hub. 2. Model 20OX Series The Model 20OX series are designed to mount on any indoor vertical surface. Mount the moni- tor in the desired location using the adhesive backing provided with the module or with screws through the mounting flange. All units are shipped with the plug-in AC/DC power supply connected to the monitor so the operator sim- ply plugs the power supply into a nearby AC outlet. Installation must be in accordance with all local codes, and/or NEC. 2.4 Wiring Connection Terminal positions on the electronics board are as follows: Terminal Function T131-1 + VDC 9 — 24 T131-2 GND OVDC T132-1 Relay NC (Normally Closed) or Out ut to Model 2102 Safe TB2-2 Relay Common T132-3 Relay NO (Normally Open) or Output to Model 2102 Alarm Table 2.1 Refer to section 6.3 for details on wiring the gas sensor module to a power supply or alarm panel. 2.5 Start-up & Operation To begin operation of the Gas Sensor Module plug in the AC/DC power supply module (for the Model 20OX Series) or provide 9 - 24 VDC from a regu- lated power supply such as one of the Siena Moni- torAlarm Panels, 2102 -XX. Use any Listed/Certi- fied Class 2 output power source each time the sensor module is powered up it will perform a warm- up for 2 - 60 minutes. During warm-up the monitor will, first, cycle through safe/alarm/safe condition at one hertz. This will be followed by a short period of continuous alarm before warm-up is completed. (NOTE: For Models 206 and 2006 that have been off power for extended periods, the warm-up alarm may sound for several hours.) 2.6 Configuration The default configuration for each module is to operate with a buzzer and a normally operating open (NOO) relay. The user can change this con- figuration using the jumpers provided. Refer to table 6.2. Page: 3 20X/20OX Gas Sensor Modules (08/04)
