3.0  INSTALLATION 

 
 
Four removable mounting feet are supplied in a plastic bag inside the enclosure c/w 
mounting bolts. These should be secured to the rear, outside corners of the         
enclosure base. The mounting feet can be loosened off and rotated to two different 
mounting positions, straight up vertically from the enclosure base or at a 45 degree 
angle from the corner of the enclosure base. 
 
For security, the PAC-44 controller should be installed inside a locked electrical,  
mechanical or instrumentation room.

7.7 SYSTEM PROGRAMMING -  RELAY OUTPUT CODES, CONT’D….. 
 

 

“2321” Setting Relay Coil State: 

This code allows the user to select the normal 

state  of  the  relay  in  non-alarm  condition  (normally  energized  or  normally                
de-energized). To achieve this,  input code “2321”, then depress push-button “3” to 
increment or “1” to decrement through the choices. Depress push-button “2” to scroll 
to the next channel. Once this function is finished, continue to depress push-button 
“2” until you reach the last channel and the system will automatically start to scroll 
through all “active” channels.  

 
 
Selection: “Fail Safe-Yes or No” 
 
 

Note: The definition of “Fail-Safe”, for the purposes of this manual, means to keep 
the relay coil in a normally energized state in non-alarm condition. 
 
 

“2313” Setting Relay Latching State: 

This code allows the user to select if one or 

more of the system relays should “latch” when activated by a gas alarm or fault 
alarm condition. Latching means that when the relay state changes because it was 
activated by an alarm condition, it is held in this changed state. To achieve this,   
input code “2313”, then depress push-button “3” to increment or “1” to decrement 
through the choices. Depress push-button “2” to scroll to the next channel. Once this 
function is finished, continue to depress push-button “2” until you reach the last 
channel and the system will automatically start to scroll through all “active” channels. 
 
Note:  The  user  must  depress  and  hold  the  acknowledge  push-button  for              
approximately 10 seconds to release the  latched relays. 
 

 
Selection: “No or Yes” 
 
 

 

“2333” Strobe Light Activation: 

The system circuit provides 24 VDC voltage    

output to power a strobe light (see photo on page-9). This code allows the user to 
select which alarm level activates the strobe light. The alarm level selected is     
common to all channels. To achieve this, input code “2333”, then depress push-
button “3” to advance through the choices. Once this function is finished, depress 
push-button “2” and the system will automatically start to scroll through all “active” 
channels.  
 
Note: Strobe always activates with all fault alarms.
