The red LED will light up to indicate that ‘Learn 

Mode’ has been selected. 

Please note that when the alarms are placed 

in ‘Learn Mode’ they can’t be inserted into the 

mounting base. 

Do not take out the battery during ‘Learn Mode’ as 

this will interrupt the learn process. 

Press and hold the test button at one alarm only, 

until it beeps and the LED flashes. This alarm will 

become the master and will start sending out a 

specific house code to the other alarms. 

As  the  other  alarms  receive  the  specific  house 

code, they will also flash the LED light.

When all alarms flash the red LED, they are 

connected and can be switched out of ‘Learn 

Mode’ and installed.
