Once the AGMSZ has been installed, set up, and powered ON, the monitor will make measurements in the 
area being sampled for ammonia gas without further operator intervention. The results of those 

measurements are shown on the front panel display.  
 

 

 

In the example shown above, MEASURE indicates that the AGMSZ is actively monitoring for refrigerant 

gas, and that currently 45 ppm of R-717 (ammonia gas) is being detected. This display also indicates that a 

peak measurement of 485 ppm has been made.  

An operator can reset the peak value to zero by pressing the ENTER button. 
A log of up to 200 previous measurements can be viewed using the PPM LOG function (Page 15). 

If the detected gas level exceeds the preset Leak, Spill, or Evacuate alarm point, then the monitor 

responds by turning ON the front panel ALARM (red) light and energizing the corresponding alarm relay. 

If the internal audible alarm is turned ON, it too will activate (AUDALRM page 16). Optional external 
alarm devices can be connected to the alarm relays to alert personnel that a Leak, Spill, or Evacuate alarm 

condition has occurred (Page 10). Pressing the front panel SILENCE button will acknowledge an alarm 
and turn OFF all alarm indicators with the exception of the front panel ALARM light. The alarm circuit 

will reactivate, however, if the alarm condition is not cleared within the time period set by the SILENCE 
function (Page 17). The ALARM light will turn OFF after the detected gas level goes below the lowest 

alarm point and after the SILENCE button is pressed.
