7.9 SYSTEM PROGRAMMING -   OTHER CODES 
 
 
“3132” Toggle Relays: 

This code allows the user to toggle the system relays to 

confirm activation of controlled devices without having to apply test gas on the     
sensors to achieve the same. This is a locked function. To achieve this, first input 
the software unlock code, then, input code “3132”. The display will indicate that the 
relay is “off” and all the relay coil amber LEDs will be go out.  Depress push-button 
“2” to toggle relay-1. This can be confirmed by the audible “click” from the relay as 
well as the amber relay coil LED going on and off as you depress “2”. Next, depress 
“3” to scroll to the next relay and repeat the last step. Continue on to the last two 
relays by repeating the last two steps or hold down “3” to scroll to the end. 

 

 
Selection: “On or Off” 
 
 

 
“1323” Unlock Code: This code is provided as a safe guard to help ensure that 
the user reads this manual before proceeding with the modification of certain 
key functions. The code functions that are locked, are so indicated in the    
explanation under each code description. Simply enter “1323” then the code 
for the function that is to be changed. The display will indicate “Unlocked”. 
 
 
“3123” Reset System Defaults: 

This  code  allows  the  user  to  reset  all  the           

programmed functions to the factory default settings. This can help if the user finds 
themselves in a position where they may have “messed up” the programming and 
cannot figure out how to get everything working properly again. To achieve this, first 
input the software unlock code, then input code “3123”. Depress push-button “2 and 
the display will indicate “finished” and the system will now be reset to factory       
settings. Factory default settings are for a basic system with Carbon Monoxide sen-
sors.
