In the following example the 24 VDC magnetic door holders drop when any
alarm is initiated or when primary AC power is lost. This prevents excessive
current drain on the system batteries when AC is lost.
Add the following SMPL equation (see the To Start SMPL Programming section
of this publication).

Note: Using TRACK causes the relay (20-01) to reenergize when AC
power is restored.
In the following example the 24 VDC magnetic door holders drop when on
alarm or 30 seconds after a power failure. If the power is interrupted for a time
less than thirty seconds, the doors will not drop.
1. Change the Door Holder circuits point types to Relay (see the Edit Points,
Edit Point Type section of this publication).
2. Add the following SMPL equation (see the To Start SMPL Programming
section of this publication).
