4208U
Universal Eight Zone Remote
Point Module
INSTALLATION AND SETUP GUIDE
FEATURES
The ADEMCO 4208U Remote Point Module (RPM) is an 8-
zone expander that allows use of available expansion zones
provided by ADEMCO controls that support polling loop
devices. Characteristics of this device include:
•
Can be optionally powered from an external DC 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).
•
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.
MOUNTING
1. Power should be disconnected
before proceeding.
2. Be sure to mount the 4208U 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 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, then hang the 4208U using the two
slots on the back.
1. INSERT BOTTOM TABS FIRST.
2. ENGAGE TOP WITH CLIP.

WIRING
CE
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 power supply connections
are optional.
DIP SWITCH SETTINGS
Zone Assignment Mode:
In the zone assignment mode, the DIP Switches on the 4208
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.
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.
UL
For all fire (NFPA) and UL Commercial
Burglary installations, the 4208U must
be tamper protected or mounted in a
tamper-protected cabinet.
