Operating Instructions - Relay/Output Functions
Page 8-2 29 July 2002 Issue 2.04
8.1 INTRODUCTION
There are three types of output in the panel whose status may be viewed on the display -
module relays, ancillary/bell relays and open collector outputs.
The status of MAF relays (Alarm, Fault, Isolate and Standby) cannot be viewed on the
display and cannot be tested (except Brigade Test tests Alarm).
The functions which can be applied to module relays and ancillary/bell relays are :
isolate/de-isolate, reset and test.
Open collector outputs are available on zone modules and cannot be isolated or reset,
but they may be tested.
For network systems: local outputs may be accessed as described in this section; relays
and open collector outputs on remote panels may be accessed as zones with zone
commands as described in Section 11.10.
8.1.1 MODULE RELAYS
Module relays are controlled by output logic that has been specifically programmed.
They may also be activated for 5 seconds during a relay test.
8.1.2 ANCILLARY RELAYS
Ancillary 1, 2 and Ancillary 3/Bell relays may be controlled either by output logic or by a
non-isolated zone alarm on any local zone which is programmed (mapped) to operate
that particular ancillary relay.
I.e. each zone may be programmed (mapped) to operate each of
Ancillary 1, Ancillary 2 or Ancillary 3/Bells when a zone alarm occurs. If a zone is
isolated it will not operate any mapped outputs when an alarm occurs.
If the Ancillary 1 or Ancillary 2 relays are controlled by output logic then the default
activation by zone alarm is inhibited, even if zones are still mapped to operate those
relays.
Operation of Ancillary 3/Bells
By default the Ancillary 3/Bells relay is a "Bells" relay if no output logic has been entered
for it. However, if an output logic equation is entered for Ancillary 3/Bells then this
overrides the "Bells" function.
