Typical battery life expectancy for DMP Model 1141 wireless 

transmitters is 4 years. DMP wireless equipment uses two-way 

communication to extend battery life.
The following situations can reduce battery life expectancy:

• If a receiver is unplugged, or not installed. 

Note: Transmitters continue to send supervision messages until a 

receiver returns an acknowledgement. 

After an hour the transmitter only attempts a supervision 

message every 60 minutes.

• When installed in extreme hot or cold environments.

The following situation can extend battery life expectancy:

• Extend transmitter supervision time in panel programming.
