If a non-latching switch is used, set the Non Latching zone attribute (page 30) 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 83).
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 29) set to YES.
Perimeter
When an event triggers a perimeter zone, the control unit immediately activates all
outputs with the “perimeter” type (see page 56). A perimeter zone is set when its
associated ward(s) is set, and ignored when its associated ward(s) is unset. A perimeter
type zone does NOT cause outputs that follow the Alarm event (pages 44, 54 and 58) to
activate.
Triggering a Perimeter zone is not counted when the panel determines whether there is a
confirmed alarm (page 89). 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 77), and a Final Exit zone must be in the same ward as the Lock Set zone.
The zone should be connected to a lock switch.
To set the system, the user first enters his/her user code at a keypad or operates a
keyswitch connected to a Keyswitch zone. The control unit starts the exit tone (the exit
time is infinite for this mode). The user then operates the Final Exit zone and turns the key
in the lock switch to “locked”. The system sets seven seconds after the lock switch contacts
open.
While the lock switch is locked, the final exit zone operates as a Normal Alm zone.
To unset the system the user turns the lock switch to “unlocked” (closing the lock switch
contacts). The keypads start a continuous tone. At this point the user can lock the
lockswitch again without causing any alarm. When the user triggers the Final Exit zone, the
control unit starts the Entry Delay timer (page 61). The user completes entry by unsetting
the system in the normal way.
Note that when the user unlocks the lockswitch, the control unit cannot generate
confirmed alarms (page 89), since an authorised presence in the building is assumed. The
control unit can generate confirmed alarms if the user locks the lockswitch without
starting the Entry Delay timer.

Note: Use only one Lock Set zone per ward.
