Chapter 9 Page 9 - 5
OPERATION:
a) Normal operation
The first zone to alarm will
cause an ‘intruder’ signal to be
sent to the ARC, which should
be interpreted as ‘unconfirmed
alarm.’
A second zone going into alarm
prior to the end of
‘confirmation time’ will be
signalled as ‘confirmed’ for
notification to the police.
A repeat trigger of the first
zone will be ignored.
If the ‘confirmed’ signal has
NOT been generated by the
end of ‘confirmation time’ the
system will reset and (subject
to setting of ‘rearm count’ in
programmable options – timers
section) rearm (re-instate). The
‘intruder’ signal WILL restore
(along with 'tamper' or 'entry
deviation' outputs if these have
been triggered).
In the event of a further
trigger before the system is
unset, a fresh 'intruder' alarm
will be generated. Subsequent
triggering of an additional zone
(within the new ‘confirmation
time’) will result in the
‘confirmation’ signal being
sent.
b) Entry Route Operation:
Applicable only if the means of
entry selected permits
sequential confirmation to
remain available (page 9-8):
If entry time has started before
an alarm occurs, no
confirmation will be signalled
until TWO zones off the entry
route have been triggered
AFTER expiration of entry time
(including pre-alarm time).
If entry through the entry
route follows an 'intruder'
alarm being generated, entry
time will commence, and only
one zone will need to be
triggered after expiration of
the timer.
If a ‘final exit’ zone remains
open when the ‘confirmation
time’ expires and the system
resets, it will automatically be
omitted. All ‘entry route’ zones
(including ER/FX and FX/ER)
sharing exactly the same area
configuration as the FX zone
will be treated as FX zones and
will start entry time, not
generate an alarm.
At rearm, any zone in fault will
be omitted, and a 'zone
isolated at rearm' signal
generated. The zone will be
reintroduced should it
subsequently close, unless ‘Re-
arm Isolates’ (in ‘SITE OPTIONS’)
is selected, in which case the
zone will remain isolated until
manually reset (unless it is a
‘Final Exit’ zone).
