Installing V-Plex ® Devices; Compatible Polling Loop Devices - Honeywell VISTA-128BPT Installation And Setup Manual

VISTA-128BPT/128BPT-SIA/250BPT INSTALLATION AND SETUP GUIDE
Installing V-PLEX
The polling loop provides both power and data to the V-PLEX devices, and is constantly monitoring the status of all
zones enabled on the loop. The maximum current draw of all devices on the polling loop cannot total more than 128mA
(unless the system uses a 4297 Polling Loop Extender Module).
Devices that can be programmed via either DIP switches or the built-in unique serial number must be set for
the serial number mode operation.
All devices on the polling loop must be wired in parallel to the [+] and [-] polling loop terminals of the control panel (24
and 25). You can wire from device to device, or have multiple branches connected directly to the control panel in a star
configuration.

The 4297 must be powered from the control panel's Auxiliary Power Output or from a UL Listed
supplementary power supply.
•
For new polling loop installations, always use twisted pair wiring. In many cases, existing non-twisted pair
wiring may be used, but it is more susceptible to interference from other sources, and may be problematic
in installations with long wire runs or in high noise environments.
•
Always locate polling loop wiring at least 6 inches (15cm) of AC power, telephone, or intercom wiring. The
polling loop carries data between the control panel and the devices; interference on this loop can cause
an interruption of communication. The polling loop can also cause outgoing interference on the
intercom or phone lines. If this spacing cannot be achieved, shielded wire must be used. (Note that the
maximum total wire length supported is cut in half when shielded wire is used.)
No more than 64mA may be drawn on any individual wire run.
