NOTES
1 Module Address Dip switch setting for each sensor module
2 Location Describe the physical location of the module
3 Sentry Channel Log the channel number to which the module is wired
4 Gas Log the name of the gas which is to be detected
5 Low Alarm Enter the value for the low alarm
Default values are: H2S: 10 PPM, Combustible 20% LEL, Oxygen 19.5%, Toxic 10 PPM
6 High Alarm Enter the value for the high alarm
Default values are: H2S: 20 PPM, Combustible 60% LEL, Oxygen 16.5%, Toxic 20 PPM
Note: Combustible Alarms cannot be set greater than 60% LEL.
7. Latch L?/H? Determine if any module will require a latching alarm and write "Y" in the appropriate
position (e.g.: N/Y indicates a non-latching low alarm and latching high alarm, Y/Y
indicates both relays will be latching). The system "defaults are N/Y.
Note: Combustible High Alarms are Latching Only
8 Factors For H2S (5100-01): Record the three (three digit) numbers which are written on the sensor
connector on each sensor.
For Combustibles: If the gas to be detected and the gas to be used for calibration are the
same write "100".
If the calibration gas is methane and a different gas is to be detected select the correct factor
from XXXXX.
Note: Combustible Gas Scaling Factors are not FMRC approved.
No factors are required for Oxygen or Toxic sensors.
9 Sensor Serial Number Record the serial number from the label on the connector of each sensor
