INSTALLATION AND SETUP GUIDE
FEATURES
The ADEMCO 4208U is a V-Plex® eight-zone expander for use
with ADEMCO controls that support 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. NOTE: The 4208U cannot be used with an
external power supply for commercial fire applications.
• Uniquely identifies 8 EOLR supervised zones (all zones use
10k resistors, supplied).
• DIP Switches can be used to set zone numbers or serial
numbers.
• When used in the serial number mode, each serial number
in the selected group can be assigned to any zone number.
• Loops A & B can be programmed for fast (10msec)
response.
• Tamper protected.
1. For all fire (NFPA) and UL Commercial Burglary
installations, the 4208U must be tamper protected or
mounted in a tamper-protected cabinet.
2. Refer to the control panel installation instructions for
U
L
specific programming/installation requirements.
3. All circuits are supervised and power-limited.
4. Use only 14-22 AWG wire.
5. Close contact type initiating devices.
6. All zones are Class B, Style B.
7. Voltage rating all zones: 11VDC max., 1.5mA max.
MOUNTING
1. Power should be disconnected before proceeding.
2.
Be sure to mount the 4208U before making any wiring
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 4208U 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 4208U
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, and then hang the 4208U using the two slots on the
back.

bead is required. Refer to the N6361 Installation
E
Instructions for wire routing instructions.
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 power supply connections are optional.

DIP SWITCH SETTINGS
Serial Number Mode:
In the serial number mode, the DIP Switches on the 4208U are
used to assign the unit to a group of 8 serial numbers. You can
assign any serial number to any zone number (except hardwire
zone numbers of the control) and you do not lose zone numbers if
you don’t use all eight loops on the 4208U. Follow steps below
using Table 2 for DIP Switch settings.
Zone Assignment Mode:
In the zone assignment mode, the DIP Switches on the 4208U are
used to assign the unit to a group of 8 consecutive zones. These
zone numbers, once designated for the 4208U, cannot be used for
anything else, even if you don’t use all 8. Follow the steps below
using Table 1 for DIP Switch settings.
Note: Zone Assignment Mode should only be used on panels that
DO NOT support Serial Mode.
