ANCILLARY RELAYS (CONTINUED)
A: Ancillary 3 relay NOT controlled by output logic (default).
The Anc 3 Relay will be energised (if not isolated) when any unisolated zone
mapped to the bells is in alarm or if there are any entries in the FFCIF alarm list
(depending on programming of FFCIF operation). The status of the Anc 3/Bells
relay can be viewed using the "RELAY" key and selecting Ancillary relay 3 and
can then be isolated, tested or reset.
The Anc3/Bells relay can also be isolated using the dedicated "BELLS ISOL" key
and also from the global ancillary isolate display using the "ANCIL ISOL" key.
For an NDU in New Zealand mode, the Bells relay is operated when a Trial
Evacuation Keyswitch is operated. The Bells relay is inhibited when a Silence
Alarms Keyswitch is operated, unless Trial Evac is also operated.
B: Ancillary 3 relay controlled by output logic.
If the ANC 3 relay is controlled by output logic, then the status of the ANC 3 relay
can be viewed using the "RELAY" key and selecting Ancillary relay 3, and can
then be isolated, tested or reset. It can also be isolated from the global ancillary
isolate display using the "ANCIL ISOL" key, but is not affected by the "BELLS
ISOL" key.
The ANC 3 relay is not affected by alarms on unisolated zones mapped to the
bells - however these alarms still affect the state of the BEL token in output logic.
Isolating the bells is a separate function from isolating the Ancillary 3 relay. The
bells can be isolated or deisolated using the dedicated "BELLS ISOL" key. If the
bells are isolated the bells isolate LED will be on and the BLI token in output logic
will be true (and BEL token will be false).
In both cases A and B above the BEL token is true if there is an unisolated local zone
mapped to the bells in alarm and the bells are not isolated or if there are any entries in
the FFCIF alarm list (depending on programming). For network systems, the BEL token
is also true if a MAF alarm state is received from a remote panel.
In case A, if BEL is true then the Ancillary 3 relay will be energised.
In case B, the Ancillary 3 relay is not affected by the state of BEL.
8.1.3 OPEN COLLECTOR OUTPUTS
There are 8 open collector outputs on each 8 Zone Module, i.e. one open collector
output for each alarm zone circuit. Any open collector output may be controlled by
output logic.
If not controlled by output logic then the output is controlled by default logic, which is the
output will be on whenever the associated zone is in alarm and the zone is not isolated.
