CAUTION

When replacing a failed zone sensor, remember to 

set the new zone sensor to the same address as 

the one being replaced. Also, If an existing zone 

sensor has failed and being replaced by a zone 

sensor relocated from another zone in the home, 

remember to set relocated zone sensor’s address 

to match the one that has failed. Not doing so 

could contribute to incorrect zone operations and 

possible equipment damage
