Zone 4 Bell Connection - DMP Electronics iComSL Series Programming And Installation Manual

Zone 4 Bell Connection
Zone 4 (Z4+ and Z4‑) can be connected to the control panel bell output. This zone detects an alarm condition on the
control panel by monitoring the voltage and cadence timing of the bell output. The communicator evaluates the first
3.5 seconds of bell cadence timing to detect the type of alarm sent. See Figure 6.

To enable alarm detection operation, Zone 4 Bell Connection must be programmed as Zone Type (A2) in Zone
Information programming. See Table 2 for bell cadence type, zone number, and type of message sent to the receiver.
The communicator generates zones 5 and 6 using the zone name of zone 4 to send to the central station. Zones 5
and 6 cannot be preprogrammed in Zone Information. CID Dialer Connection cannot be used when using Zone 4 Bell
Connection. See Figure 7.
