NOTE: If using the 5193SD/SDT V-Plex smoke detectors the "Smart" option must be selected in zone programming or when
they enroll unpredictable results may occur if the smoke goes into a High Sens or Low Sens condition.
To install polling loop devices, perform the following steps:
Step Action
Select devices from the list of compatible devices shown previously.
Set the DIP switches in the device (if required). Refer to the device’s instructions for the DIP Switch Tables.
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 3-14
). 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
Wire each device to the polling loop, making sure of the correct polarity (refer to the device’s instructions).
NOTE: If you are using serial number devices, and intend to enroll each device through the keypad
automatically, wire no more than 25 of these devices to the control at a time. Then power up and
program them before connecting the next 25. Leave previously enrolled devices connected.
If you intend to manually enter the serial numbers through the keypad or through Compass downloading
software, all the devices may be connected before powering up to program.
