VISTA-50P/VISTA-50PUL Installation and Setup Guide

Installing RPM Devices

The polling loop provides both power and data to the
RPM 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 64mA (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 4208 must be mounted either inside the
U L
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 4194 is not UL Listed.
• The 4297 must be powered from the control
panel's Auxiliary Power Output or from a UL
Listed supplementary power supply.
• The 7500 and 9500 detectors are not UL Listed.

•
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 six
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.
• When a star configuration is used, the total
length of all wire runs combined cannot exceed
4000 ft (2000 ft. if you are using unshielded wire
in conduit or shielded wire).
IMPORTANT NOTE: If the installation exceeds or deviates
from these parameters, refer to the application note on the
Honeywell website for additional information. To access
the application note:
1. Go to the honeywell.com/security website
2. Click the Honeywell Security & Custom Electronics link.
3. Click the Commercial link.
4. Click the Documentation link.
5. Click the V-Plex Application Note.
To install polling loop devices, perform the following steps:
Step Action
Select devices from the list of compatible
1
devices shown previously.
Set the DIP switches in the device (if
2
required). Refer to the device's instructions
for the DIP Switch Tables.
Mount each device in the desired location.
3
Refer to the device's instructions.
Run wires from the control panel to each
4
device on the polling loop (see Figure 3-16).
No individual wire run may exceed the
lengths shown in the following table.
