Keyswitch
A Keyswitch zone is normally connected to a shunt-lock or keyswitch, which can be used
to set or unset assigned wards.
Assuming the zone's Inverted attribute is set to the default of NO (page 32), if a ward is
currently unset, opening the zone contacts starts the process of setting the ward.
If a latching switch is used, the zone contacts must remain open until the ward is set,
otherwise the setting procedure is cancelled. Once set, the ward can be unset in the
normal manner from a keypad or by closing the zone contacts.
If a non-latching switch is used, set the Non Latching zone attribute (page 32) to YES. The
first operation of the switch sets the ward, and the next unsets the ward.
Shunt Key
A Shunt Key zone is normally connected to a shunt-lock or keyswitch that is monitored at
all times. While the zone contacts are in the triggered position (i.e. by default open), the
panel shunts (i.e. isolates) all zones that have the Shuntable attribute (page 32) set to YES
and belong to a ward assigned to the Shunt Key zone. Any type of zone can be shunted.
If you do not assign any wards to the Shunt Key zone, opening the zone contacts shunts
all zones that have the Shuntable attribute set to YES and are directly connected to the
same device as the Shunt Key. For example, if the shunt key is connected to an XNode,
the system shunts all shuntable zones connected to the same XNode. Similarly, if the
shunt key is connected directly to the panel, the system shunts all shuntable zones
directly connected to the panel. Note: A Shunt Key zone cannot itself be set with the
Shuntable attribute.
If a non-latching switch is used, set the Non Latching zone attribute (page 32) to YES. The
first operation of the switch shunts the zones, and the next removes the shunt.
Tamper
A Tamper zone is monitored at all times and is used to monitor the tamper status of
external equipment. When triggered in the set condition, a full alarm is generated, unless
overridden by option 1-8-4 (page 72).
This zone type can be used for a negative tamper return for monitoring SABs, etc. When
using type of monitoring, the zone input is a normally-negative signal (rather than a
normally-closed contact across the zone terminals), and therefore the zone MUST have
the Inverted attribute (page 32) set to YES.
Perimeter
This is similar to the Normal Alm zone type, but does not cause outputs that follow the
Alarm event (pages 43, 51 and 55) to activate. However, outputs that follow a Perimeter
event (page 54) are activated immediately.
Triggering a Perimeter zone is not counted when the panel determines whether there is a
confirmed alarm (page 77). Perimeter zones are usually connected to outside detectors,
which have a higher probability of being accidentally triggered.
Lock Set
Use this zone type if you want a ward's Final Exit zone to be considered as a Normal Alm
zone while the exit door is locked. To use this zone type, the Setting Mode must be set to
Lock Set (page 66), and a Final Exit zone must be in the same partition as the Lock Set
zone. The zone should be connected to a lock switch.
