If your Data Aire Security System panel isn't powering on, try these steps: First, ensure the disconnect switch is turned to the ON position. Next, check that the hard power ON/OFF switch is also set to ON. After that, inspect the remote shutdown contact and verify the P5 connections on the DAP-III Control Module. Also, check and reset the circuit breaker on the transformer. Finally, replace the fuse with a 2 amp fuse if necessary.
