AMC-SIR Refrigerant Gas Sensor/Transmitter 3 PRODUCT DESCRIPTION The AMC-SIR Refrigerant Gas sensor/transmitter unit is designed to provide continuous, reliable surveillance of surrounding air for the target gas listed in the Factory Calibration (Section 2.3). Based on the physical measurement method of infrared absorption, it provides the best technique for reliable, precise measurements and selectivity. -
Page 8: Installation And Operation
4.1 LOCATION AND MOUNTING Mount the AMC-SIR Refrigerant Gas sensor/transmitter on a solid, non-vibrating surface or structure in an area where the ambient concentration of gas is not directly affected by the presence of clean air supply, ventilation systems, or blockage by surrounding articles and sources of interference gas or contaminants. -
Page 9: Wiring
AMC-SIR Refrigerant Gas Sensor/Transmitter 4.2 WIRING The AMC-SIR Refrigerant Gas sensor/transmitter was designed to operate with a power supply voltage range of 14V to 28VDC. It can be interconnected to a suitable Armstrong monitor panel or be powered from a stable 14-28VDC power source, with its 4-20mA signal interconnected to a suitable measuring device. -
Page 10: Transmitter To Monitor Wiring
Figure 4-3 Jumper (JP3) installed 4.2.1.2 TRANSMITTER TO MONITOR WIRING When connecting to an AMC Monitor, the AMC-SIR Refrigerant Gas sensor/transmitter is wired with a 3-conductor shielded cable. Fig. 4-4 shows the connection between the AMC-SIR Refrigerant Gas sensor/transmitter and an AMC Monitor. In this configuration, power is provided via the Monitor. -
Page 11: Transmitter Current Output
To accomplish this, a high-precision resistor must be connected to the current input of the non AMC monitor as a shunt. See Fig. 4-6. The resultant voltage drop across the resistor then linearly reflects the concentration value of the measured gas. - Page 12 TRANSMITTER HOUSING REMOVED FOR CLARITY TRANSMITTER TO MONITOR SHIELD NON-AMC SigV MONITOR LED1 POWER CHASSIS GND NOTE: ALL WIRING MUST PASS THROUGH CONDUIT OPENING LOCATED AT THE BOTTOM OF ENCLOSURE.

2 minutes, in a gas-free environment. The sensor signal can fluctuate during the warm-up period. When the boot phase is finished, and when all test routines have properly finished, the AMC- SIR Refrigerant Gas sensor/transmitter automatically switches to normal operating mode and provides a signal output proportional to the gas concentration. -

AMC-SIR Refrigerant Gas Sensor/Transmitter 4.3 CABLE SELECTION The following section details the cable selection needed to ensure proper operation of the AMC- SIR Refrigerant Gas sensor/transmitter. The figure below is an aid for cable selection. A 3-conductor shielded cable is employed for interconnection. -

Page 16: Zero Verification
The zero point should be checked with zero gas. Gas should be applied at 0.5lpm using the AMC-FL1 calibration adapter, as shown in Figure 5-1.Once the sensor has been completely purged, the output measured at the cal jack should be between 3.9 - 4.1mA. If the measured value is: ... -
Page 17: Zero Recalibration Procedure
1. Disconnect power at the plug-in TB-2 terminal. Ensure both JP2 and JP3 jumpers are not installed, then re-connect power to AMC-SIR. Wait for Sensor to finish boot up stage (3 minutes after power up) before applying the zero gas as above and make sure that the sensor has been completely purged. -
Page 18: Maintenance
6 MAINTENANCE 6.1 GENERAL The AMC-SIR Refrigerant Gas sensor/transmitter unit should be brushed or wiped as required, depending on the rate of accumulation of any dust or dirt. To avoid sensor damage, the unit MUST NOT be submerged in any liquids.
