The 4-20mA output will then ramp up from 4 to 16 mA over the next 130 seconds of the test, so if the circuit is 
wired in the normal manner, the control panel or building automation system should respond. 

e.

 

At the end of the test cycle, the fan & alarm relay will be in standby mode and the 4-20 mA output will

Manual Operation Test 

This option gives the user the opportunity to manually initiate an individual test for each relay, the analog output and the sensor 
response to gas.  

From normal operation mode press the 

42T

Next

42T

 button 2 times to get to the Test Mode (tSt).  

Press the

 button once to get into the Test Menu.  

Press the

 to initiate the selected test.  

Note that if the relay or 4

Calibration and Test Kits 

 

   

WARNING

 

The following steps must be performed when conducting a calibration or calibration verification 
test (bump test) to ensure proper performance of the monitor. Failure to do so may adversely 
affect product performance.  

 

When  performing  a  calibration  or  calibration  verification  test  (bump  test),  only  use 
certified calibration gas at the required concentration level. 

 

Do not test with expired calibration gas. 

 

Do not cover or obstruct display or visual alarm cover. 

 

Ensure sensor inlets are unobstructed and are free of debris 

Failure to follow instructions outlined in this user manual can result in sickness or death.
