Sentry Industries 5000 User Manual

 

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:  H

2

S: 10 PPM, Combustible 20% LEL, Oxygen 19.5%, Toxic 10 PPM 

6 

High Alarm 

Enter the value for the high alarm 
Default values are:  H

2

S: 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
