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. See Zone 4 Bell Cadence
Information in the Appendix for cadence timing. To enable alarm detection operation, Zone 4 Bell Connection
must be programmed as Zone Type (A2) in Zone Information programming. The type of Cadence sent to the
CellComSL Communicator, the Zone Number, and type of message sent to the SCS-1R or SCS-VR receiver are
listed below:

Note: Zone 5 and 6 are automatically generated by the CellComSL Series, using Zone 4’s Zone name to send to
the Central Station. Zones 5 and 6 cannot be preprogrammed in Zone Information.
