NOTE: If using the new 5193SD/SDT V-Plex smoke detectors (or older 5192SD/SDT with the maintenance DIP sw enabled)
the "Smart" option must be selected in zone programming or when they enroll unpredictable results may occur if the smoke
goes into a High Sen or Low Sens condition.
To install polling loop devices, perform the following steps:
Step Action
1 Select devices from the list of compatible devices shown previously.
2 Set the DIP switches in the device (if required). Refer to the device’s instructions for the DIP Switch Tables.
3 Mount each device in the desired location. Refer to the device’s instructions.
Run wires from the control panel to each device on the polling loop (see Figure 3-15). No individual wire run
may exceed the lengths shown in the following table.
Maximum Polling Loop Wire Runs
Wire Gauge Max. Length
#22 gauge 650 feet
#20 gauge 950 feet
#18 gauge 1500 feet
#16 gauge 2400 feet

5 Wire each device to the polling loop, making sure of the correct polarity (refer to the device’s instructions).

Polling Loop Supervision
A short on the polling loop is indicated by a trouble on zone 997 and reports as a trouble condition only.
If a device on the polling loop fails (the panel cannot "see" that device), the system displays a trouble condition for all
zones on that device. If the panel is armed when a device fails, and the zone is a burglary zone, the will go into alarm.
A trouble on zone 997 prevents a partition from being armed, unless all polling loop zones on that partition are
bypassed.
