- during the first installation 
- during a cell or sensor replacement  

 

2.6.

 

Code (access) menu  

This  menu  changes  the  access  code  for  various  menus  (1000  in  standard  upon  shipment  of 
equipment): 
 

-

 

display the CODE menu (+ and – key) 

-

 

validate it (enter) 

-

 

display current code 

-

 

indicate the new code using the + and – keys

-

 

finally confirm (yes/no/enter) 

 

2.8.

 

TEST menu (TST) 

Disables the relays embedded to MX15 upon voluntary activation of alarms through injection of a 
standard gas on the sensor to test the alarms or to calibrate: 
 

-

 

display the TST menu (+ and – keys) 

-
