Mounted internally this module has 4 heavy duty
relays each with a single changeover contact
(rated 5A @ 30Vd.c.). The relays are normally
energised from the individual zone outputs of the
zone module.

1700 Relay PCB
This module allows up to 4 groups of sounders to
be activated in a pre-programmed response from
up to 10 zones of detection. Each group can be
programmed to respond in either pulsing or
continuous output. Each output is fused at 1A
@24Vd.c.

1700 Sector Sounder PCB
This module allows for extra power to be supplied
to a sounder circuit. It is normally used when
large numbers of sounders are required in one
circuit or where long distances create volt-drop
problems. Additional current is 1.5A.

This module provides the power to each
detection zone which respond to four conditions,
open-circuit fault, quiescent, alarm or short-circuit
fault. Individual indication is given for either Alarm
or Fault. Each zone has a corresponding output
which is energised in an alarm condition and is
suitable for driving zonal relays and/or auxiliary
modules i.e. multiplexed repeater.
