Installing V-Plex Devices - Honeywell VISTA-128BPEN Installation And Setup Manual

Installing V-PLEX Devices

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.

U L
• The 4208 must be mounted either inside the control panel's cabinet or in a separate enclosure that has a tamper-
supervised cover.
• The 4190WH right loop must not be used, and the left loop must be EOLR-supervised.
• The 4278 right loop cannot be used.
• 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.
