Value Type Description
11/12 Keyswitch There are two Keyswitch zone types: Momentary and Fixed.
Use these for zones that connect to an access control keypad,
electronic key or other hardwired device used to set or unset the
system:
11 Momentary Keyswitch (KM)
12 Fixed (or latched) Keyswitch (KF)
The keyswitch or similar device can be used to set and unset
the level or partition to which the zone is assigned. It cannot be
used to reset the system.
In a single system, do not assign a Keyswitch zone to levels B,
C or D if you have assigned one to Level A (full system). In a
partitioned system, do not assign more than one Fixed
Keyswitch zone to a partition.
Note: In a partitioned system with a keyswitch for each partition,
operating a second keyswitch whilst the first partition is starting
to set will prevent the second partition from setting.
13 Anti-Mask
Zone (AM)
Use this zone type for the anti-mask outputs of detectors with
this facility. Connect the detector's alarm and contact wiring to
one zone (for example, Zone 07) and its anti-mask outputs to
the zone above (for example, Zone 08). Assign the Anti-Mask
type to the higher zone; that is, the one connected to the anti-
mask outputs (Zone 08 in the example).
If an Anti-Mask zone is violated, the control unit starts a Tamper
Alarm and shows the message "AM Tamper" on the keypad
display. It logs the event to the zone connected to the detector's
alarm and contact wiring (Zone 07 in the example). Command
136 defines whether an Anti-Mask zone can be reset by a user
or only by the installer.
To use two-zone anti-masking, Command 88 must be set to 0
(Mask only).
14 Forbikobler
(FB)
This zone type is a Scandinavian type of Entry/Exit zone (the
word "forbikobler" means "bypass" in Danish). Use this type for
zones connected to standalone external keypads or access
controllers. If the zone is triggered by the external keypad during
the exit time, the control unit stops the exit time and sets the
system. If the zone is triggered while the system is set, the
control unit starts the entry time. Use zone attribute X7 to select
an entry timer for the zone (page 12) and Commands 201–4
(page 66) to set up the entry timers.
15 AC Fail (AC) This zone type is triggered by a failure in the AC input to an
external power supply. Command 134 defines whether a zone of
this type can be reset by a user or only by the installer.
Command 137 defines whether the user can override the fault to
set the system. In a partitioned system, AC zones are always
allocated to Partition A.
16 Low Battery
(LB)
This zone type is triggered by a low voltage in the battery in the
external power supply. In a partitioned system, LB zones are
always allocated to Partition A.
