Result: If fire is detected and the signals are bypassed, release doors and sound
signals.

Result: Whenever doors and signals are bypassed, a system trouble is generated.
In the following example any smoke detector alarm (automatic device) causes
a Slow March Time on signal circuit 1. Any manual device (manual station)
causes evacuation signals (Temporal Code) to sound over signal circuits 2 and 4
until silenced.
1. Create a user list that includes all zones for pre-signal operation (see the
Lists, Add Points to a List section of this publication).
2. Label the user list "Pre-Signal Alarm Zones” (see the Edit Points, Edit
Point Label section of this publication).
3. Add the following SMPL equations (see the To Start SMPL Programming
section of this publication).
