ADEMCO 4208SN
V-Plex Eight Zone Expander
Installation and Setup Guide
FEATURES
The ADEMCO 4208SN is a V-Plex
®
eight zone expander for use with
Resideo controls that support serial number V-Plex (polling loop)
devices. Characteristics of this device include:
• Can be optionally powered from the control panel aux. power
supply to reduce the amount of current draw from the polling loop.
• Uniquely identifies 8 EOLR supervised zones (all zones use 10k
resistors, supplied).
• Each zone is identified by a unique serial number, which is
assigned via on-board DIP Switches.
• Detects faults on all zones within 400ms of occurrence. Loops A
& B can be programmed for fast (10ms) response.
• Provides cover tamper protection, which may be enabled or
disabled via on-board DIP Switches.
MOUNTING
1. Power should be disconnected before
proceeding.
2. Be sure to mount the 4208SN before making any
wire connections.
When mounted remotely, tamper protection is required. Holes on the
back of the module’s housing permit it to be mounted horizontally or
vertically. Wires can exit from the side or the breakout on the back of
the housing. To enable tamper protection, set DIP Switch 8 to OFF
and attach the tamper magnet (provided) (Figure 1) to the module
inside cover. Be sure to enable the expansion zone tamper option at
the control (program field *24 = 0). If the module’s cover is removed,
the magnet attached to the cover (positioned near the reed switch) will
cause a tamper signal to be sent to the control for every active zone on
the 4208SN module. When the installation is complete, install the
cover and affix the Serial Number and Zone Assignment Tables to the
inside cover of the control.
When mounted inside the cabinet with the control, the 4208SN should
be mounted horizontally and does not need tamper protection,
provided the cabinet is supervised. Insert two screws into the raised
metal tabs leaving the heads app. 1/8” exposed, then hang the
4208SN using the two slots on the back.
1. INSERT BOTTOM TABS FIRST.
2. ENGAGE TOP WITH CLIP.

For CE installations, ADEMCO N6361 EMI
suppression bead is required. Refer to the N6361
installation guide for wire routing instructions.
Polling loop and protection loop wires can be brought in either through
the back or front of the unit by removing the knockouts. Use 22 gauge
twisted pair wire for polling loop connections. All protection loops use
10k EOL resistors (included). A maximum resistance of 300 ohms is
allowed on protection loops (excluding EOLR). See Figure 2 for all
connections. Keep in mind that connections to the polling loop are
always required, while aux. power connections are optional.

For UL commercial and household fire installations,
no more than one wire per terminal may be
connected.

IF USING AUXILIARY POWER ON COMMECRICAL
FIRE/BURG COMBINATION SYSTEMS
(e.g. VISTA-128FBP), DO NOT CONNECT THE
POLLING LOOP GROUND ON TERMINAL 2.
AUXILIARY POWER CAN ONLY BE USED IN
BURGLARY APPLICATIONS.

1. For dry, indoor use only.
2. Do not install in air-handling spaces.
3. All circuits are supervised and power-limited.
4. Use only 14-22 AWG wire.
5. Refer to the control panel installation
instructions for specific programming /

For all fire (NFPA) and UL Commercial Burglary
installations, the 4208SN must be tamper protected
or mounted in a tamper-protected cabinet.
