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 “Ext WD
F
ault” alert.
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 “HUD Fault” alert. If a user tries to set the system when this zone is
active, the control unit displays the fault. 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 49). 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 34), and activates any
output of type Zones Shunted (see page 46).
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.
If a shunted detector is active at the time a user restores the Shunt Key Latching
zone, the control unit ignores the state of the Shunt Key Latching zone. When all
active shunted zones are restored, the control unit will recognise the Shunt Key
Latching zone and un-shunt zones when the key is restored.
