ADEMCO 4297
V-Plex
®
Loop Extender Module
For Use With Control/Communicators Supporting V-Plex
®
Loop Devices

INSTALLATION AND SETUP GUIDE
GENERAL INFORMATION
The ADEMCO 4297 V-Plex
®
loop extender module is an
accessory for use with Ademco control panels that support
V-Plex (polling loop) devices. The 4297 module receives
signals from the control panel via its "input" loop, and then
re-transmits boosted copies of these signals via its
"extension" loop.


The 4297 draws power for its internal circuitry and its
extension loop from a supplementary power supply such as
the control panel’s auxiliary power output.
Also, the 4297 isolates open and short circuit faults
occurring on its extension loop from its input
loop. These characteristics allow the 4297 module to be
used to extend the control panel's polling loop, to provide
additional polling loop current, and to provide

electrically
isolated branch loops.


The 4297 module is fully supervised and causes the control
panel to trigger supervision fault indications for devices
wired to the extension loop when operating power to the
module fails, or when an open or short circuit occurs on the
extension loop. Refer to the control panel's installation
instructions for the type of supervision fault indication
provided.

Important Notes:
*
The 4297
cannot
be used to increase the number of
polling loop zones supported by the control panel.
*
The 4297 is
not
designed to be used in a Class A
wiring configuration.
MOUNTING
For UL burglary and all fire installations:
Mount the 4297 module inside a UL Listed enclosure such as
the control panel's enclosure. Note that the enclosure must
be UL Listed for the desired application; i.e., use an attack-
resistant enclosure with a tamper switch for commercial
burglary applications.
For non-UL certified installations:
Mount the 4297 module directly on a surface using the
slotted holes located on the back of its housing (mounting
screws provided). Feed the wires through the slot on the side
or through the breakout located on the back of the housing.
Affix the connections label provided to the inside of the 4297
module's cover or in the control panel cabinet, if used.
WIRING CONNECTIONS
The 4297 module provides a 9-position terminal block for
making power, earth ground and polling loop connections.
The screw terminal assignments on this terminal block are
described in Figure
1
.
UL NOTE:
Use only 14-22 gauge wire.

ULC

For ULC fire installations, the 4297 can be used to
connect the fire alarm control panel to the Vista fire
transmitter. It is not to be used to connect fire alarm
detectors to the ADEMCO (Vista) fire transmitter.

Figure 1. 4297 Wiring Connections

Power Supply Connections
The 4297 module can draw power for its internal circuitry
and its extension loop from a supplementary power supply
such as the control panel's auxiliary power output. See
Figure 2.

U
L

All power-limited wiring must be separated from non-power
limited and high-voltage wiring by 1/4" (6.4 mm).

Refer to the control panel installation instructions for
programming / installation requirements.


When Using One 4297
Use one 4297 to extend the polling loop, to provide additional
polling loop current, or to provide an extension loop which is
electrically isolated from the input loop.
Make the connections shown in Figure 3 when only one 4297
module is used. Make sure that the wire run length limits
indicated in Table
1
are not exceeded.

When Using Multiple 4297s
Use multiple 4297s to provide up to eight extension loops
which are electrically isolated from each other, or to provide
more current than one 4297 can supply.
Make the connections shown in Figure 4 when multiple 4297
modules are used. Do not wire 4297 modules in series (i.e.,
do not wire one module’s extension loop to another module’s
input loop). Do not use more than eight 4297 modules in
parallel unless otherwise stated in the control panel's
installation instructions. Make sure that the wire run length
limits indicated are not exceeded.
Important Notes:
* Twisted pair is recommended for all polling loop wire runs.
* If an intercom system is being used, keep the polling loop
wiring as far from the intercom wiring as possible
(minimum 6 inches). If this spacing cannot be achieved, use
shielded wire. Note that use of shielded wire reduces the
maximum permissible polling loop wire run length, as
indicated in Table
1
on page 2
.
