Polling Loop Supervision

A short on the polling loop is indicated by a trouble condition on its supervisory zone (zone
997). This reports as a trouble condition only. As such, a polling loop should be assigned
either zone type 05 or type 19, if annunciation as a trouble condition is desired.
If a device on the polling loop fails (the panel cannot see that device), the partition or
partitions that use the device will display a trouble condition for all zones associated with the
device. If the panel is armed when a device fails, the zones associated with that device will
cause an alarm on the corresponding partition(s) except for zone types 05, 06, 07, 08, and 09.
Zone types 05, 06, 07, 08, and 09 are reported as check/trouble if the device fails while the
system is armed.
A trouble on zone 997 will not prevent a partition from being armed, as long as all polling loop
zones on that partition are bypassed.

Programming Polling Loop Zones

Each polling loop zone must be programmed into the system, which assigns characteristics
that define the way the system responds to faults on that zone. Refer to #93 Menu Mode in
the Quick Start Guide for instructions on programming polling loop zones.

Checkout Procedure for Polling Loop Zones

After installation of all polling loop zones is complete, power has been applied to the system,
and the zones have been programmed, each partition of the security system should be
checked as follows:
1. Be sure that all devices and sensors connected to the polling loop are not in a faulted
state. Doors and windows with contacts should be closed, PIRs should be covered (use a
cloth to mask them temporarily, if necessary).
2. With all hardwired and polling loop zones intact, the alpha keypads connected to the
system should display:
3. If the keypad(s) begins beeping and displays the word CHECK or TRBL along with a
zone or zone numbers, the system either does not see the displayed zone(s) or the
tamper switches are tripped. Please check the DIP switch settings for the zone(s), the
connections, and/or that the covers for the units with tamper switches are in place. Once
the situation has been corrected, enter the [User Code] + [OFF] sequence twice to clear
the trouble.
4. If the following is displayed, press the [ ] key to display the faulted zone(s):
5. Restore any faulted zone(s) as necessary. When the DISARMED...READY TO ARM
message is displayed, you can proceed to the next step.
6. Fault and then restore every contact or sensor on each zone individually to ensure that it
is being monitored by the system. Each time a zone is faulted, the keypads in the
partition to which the zone is assigned should display the number of the faulted zone.
Tripping fire and panic zones will cause external sounders to sound and may
