"Door holder mode" refers to when the load is normally energised with the relay itself de-
energised, e.g., for door holders. The normal state is for the door to be held open by
energised magnets (i.e., the load is energised) and the relay itself is de-energised. To close
the door the relay energises and disconnects power to the load. "Load mode" is the
opposite of door holder mode, whereby the load is de-energised when the relay is de-
energised.

ANCILLARY RELAY PROGRAMMING OPTIONS
To program ancillary relay options, select option 4:System config from the base
programming menu, then option 3:outputs, then option 1:Ancillary relay options.
Ancillary Relay Options
The options which may be entered for ANC 1, 2, and 3 are:
Supervision enabled (E) or disabled (D).
Supervision latching (L) or non-latching (N) (applies to faults).
Fault and isolate mapped (M) or not mapped (N) to the MAF.
Supervision is load (L) or door holder (D) mode (not for Anc 3)
Isolatable (yes/no)
Testable (yes/no)
Supervise Activated State (yes/no)
The default setup (by database re-initialise) is.
ANC 1: supervision enabled, non-latching, mapped to MAF, Door holder, isolatable,
testable, supervise activated state.
ANC 2: supervision enabled, non-latching, mapped to MAF, Load mode, non-isolatable,
non-testable, supervise activated state.
ANC 3: supervision enabled, non-latching, mapped to MAF, non-isolatable, non-testable,
supervise activated state.
7.4.3
WARNING SYSTEM/ EXTERNAL BELL MAP TO MAF
The mapping of Warning System and External Bell to the MAF can be enabled or disabled.
If enabled, isolate conditions signal Brigade fault and Brigade isolate respectively.
To program these options, select option 4:System config from the base programming menu,
then option 3:Outputs, then option 2:Warning system/ External bell. This produces the
following menu
1:Warning system maps to MAF 2:External bell maps to MAF
