Supervising the Alarm Output
To wire the alarm output using the supervision feature, perform the following steps:
Step Action
1 Wire polarized fire-indicating devices to the alarm output as shown in Figure 3-6.
2 Wire nonpolarized burglary indicating devices to the alarm output using a polarizing diode (two 2A diodes
supplied), as shown in Figure 3-7.
3 Program Zone 970 with a response type of 05 (trouble by day/alarm by night).
NOTE: When supervising the bell output (zone 970), only one device can be connected to the alarm output
