the control unit activates any output of type External PSU Fault and causes an alert
that displays “External power fault” on the keypad.
If the alarm system is set, the control unit logs the event, starts any programmed
communication, but does not start an alert until the system is unset.
This zone type is not available for radio zones.
External WD Fault
– WD (15)
Use this zone type to monitor the fault output of an external warning device. If a
warning device triggers a zone with this type, the control unit generates an alert that
displays “Ext WD Fault” on the keypad.
A user can override this fault and set the system.
If the alarm system is set, the control unit logs the event, starts any programmed
communication, but does not generate an alert until the system is unset.
This zone type is not available for radio zones.
HUD Fault
– HUD (16)
Use this zone type to monitor the fault output of wired hold-up devices that are
capable or reporting faults. When a detector triggers a zone with this type, the control
unit generates
an alert that displays “HUD Fault” on the keypad. If a user tries to set
the system when this zone is active, the control unit displays the fault on the keypad.
The user can override the fault and carry on setting.
If the alarm system is set, the control unit logs the event, starts any programmed
communication, but does not generate an alert until the system is unset.
This zone type is not available for radio zones.
Log Only
– LO (17)
When a detector triggers a zone with this type, the control unit logs the event and
activates any outputs that are programmed to follow this zone. The zone is active
whether the system is set or unset. Typical uses for this zone type are for integrating
the alarm system with a CCTV system.
Note:
Zone Follow outputs will activate on both alarm and tamper of a Log Only
zone.
Log only zones can be allocated to one or more partitions, and can use the Chime
attribute.
Exit Terminate ET (18)
Use this zone type to terminate setting when the system or partition exit mode is Exit
Terminate (see page 72). This zone type is designed for a normally-open momentary
switch.
Note that this zone type is armed during the setting time, but inactive both while the
system is set, and while the system is unset. If you apply the Chime attribute to this
zone, the system will give a chime tone when the zone is activated both while the
system is unset and while the system is set.
Shunt Key Latching SKL (19)
In a part-setting system (one with no partitions):
When a user activates this type of zone,
the control unit “shunts” any zones in
which the attribute Shuntable is set to Yes (see page 50), and activates any
output of type Zones Shunted (see page 69).
While zones are shunted, the control unit ignores the alarm signal from their
detectors.
The detectors remain shunted until a user restores the Shunt Key Latching zone.
