INSTALLER LEVEL PROGRAMMING
Note 9: Bypassable Zones - Fire Trouble
Condition
All zones may be programmed as Bypassable. If a
Fire, Verified Fire, or Fire Supervisory zone is
bypassable and is bypassed, a Fire Trouble condi-
tion occurs and is reported. The condition remains
until the zone is unbypassed.
Note 10: Secure Watch
The Secure Watch attribute may only be used with
Burglar, Critical Condition Monitor, Non-Alarm, Uni-
versal, and Universal Logged zones. It is ignored for
all other zone types.
If a Burglar zone has Secure Watch enabled, then
the Secure Watch only applies when the zone is dis-
armed and not bypassed. Whenever the zone is vio-
lated, disarmed or unbypassed, the zone’s Secure
Watch timer is reset to the programmed time. If
that timer expires and the zone is disarmed and not
bypassed, then a Secure Watch Trouble event is
posted for the zone to be reported. The trouble
condition is not displayed on the keypad and it does
not prevent the area from being armed. A Secure
Watch Trouble Restore event is posted for the zone
to be reported if the zone is then either violated,
armed, or bypassed.
If a Critical Condition Monitor, Non-Alarm, Univer-
sal, or Universal Logged zone has Secure Watch en-
abled, then the Secure Watch only applies when the
zone is not bypassed. When the zone is violated or
unbypassed, the zone’s Secure Watch timer is reset
to the programmed time. If that timer expires and
the zone is not bypassed, then a Secure Watch
Trouble event is posted for the zone to be reported.
The trouble condition is not displayed on the key-
pad. A Secure Watch Trouble restore event is posted
for the zone to be reported if the zone is either vio-
lated or bypassed.
While a zone has a Secure Watch Trouble condition,
its corresponding Secure Watch signaling device
(programmable output) will stay ON steady.
Note 11: The Listen-In Module
The Listen-In Module must be wired to the telephone
lines in series with and behind the control panel.
The Listen-In Module must be connected to the panel
as follows. A Line-Seized indicator line must be con-
nected from the ACTIVE output on the Listen-In
Module to an assigned Listen-In Module zone on
the panel. A Listen-In output line must be connected
from an assigned output on the panel to the ACTI-
VATE input on the Listen-In Module.
The zone programmed as the Listen-In Module zone
is area independent and is used by the panel to de-
termine whether or not the Listen-In Module has
seized the telephone line and has the microphone(s)
active. The output programmed as the Listen-In
Output may be assigned to any combination of ar-
eas. It is used by the panel to signal the Listen-In
Module for activation.
The Listen-In Module may be configured in one of
two modes, Instant Seize mode or Answer mode.
If the Listen-In Module is configured in Instant Seize
mode, then when it is first signaled from the panel,
it instantly seizes the phone line and signals the panel
through the Listen-In Module zone but does not turn
on the microphones. When the panel releases the
connection to the Central Station and deactivates
the Listen-In Output, the Listen-In Module already
has the line seized and assumes the connection.
If the Listen-In Module is configured in Answer mode,
then after the panel has signaled it by activating and
later deactivating the Listen-In Output, the Listen-In
Module starts its incoming call timer. The incoming
call timer starts when the Listen-In Output is deacti-
vated and runs for five minutes. If a call comes in
while the timer is running, then the Listen-In Mod-
ule answers the call on the first ring. At that time, it
signals the panel through the Listen-In Module zone
that it has seized the line.
When the control panel detects the Line-Seized sig-
nal from the Listen-In Module zone, it temporarily
silences all alarm tones at the Control Stations and
the Bell Outputs, although the alarm output timers
continue. When the Listen-In Module releases the
phone line, it removes the Line-Seized signal to the
panel. When the control panel detects the Line-
Seized signal has been removed, it no longer silences
alarm tones at the Control Stations and Bell Out-
puts. The Bell Outputs are reactivated if they have
not timed-out.
Also, when the panel detects the Line-Seized signal
from the Listen-In Module zone and gets an event
(any event) to report to the Central Station, the panel
