Perform a Battery Test 
 
The backup battery is located on the rear of the ZeroWire behind a cover. It provides 
temporary power to the ZeroWire when mains power is not available. This may occur 
during a power outage or an intruder cutting power to a property.  
The ZeroWire will automatically test the battery each day. If the battery fails then your 
system can no longer protect your property in a power outage. This is why replacing it 
when needed is very important.  
The battery is a consumable part of the system and should be replaced every 3 years or 
when the battery test fails (whichever is sooner). Contact your service provider for 
replacement parts. 
A low battery or mains fail status message may take up to 5 minutes to clear after a mains 
power fail event.

Perform a Communicator Test 
 
The communicator is a part of the ZeroWire responsible for sending alarm messages. The 
communicator test is only available if your security system has been set up to report to a 
central monitoring station. Proper operation of this is very important for alarm reporting. 
When testing your communicator, no sirens will sound and a test message will be sent to 
the central monitoring station.
