Eight Zone Expander



Installation and Setup Guide
GENERAL INFORMATION
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 a
ux. power
supply to reduce the amount of current draw from th
e polling
loop.
NOTE:
The 4208U cannot be used with an external
power supply for commercial fire applications.
•

Uniquely identifies 8 EOLR supervised zones (all z
ones use
10k resistors, supplied).
•

DIP Switches can be used to set zone numbers or se
rial
numbers.
•

When used in the serial number mode, each serial n
umber in
the selected group can be assigned to any zone numb
er.
•

Loops A & B can be programmed for fast (10msec) re
sponse.
•

Tamper protected.
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 require
d. Holes on
the back of the module’s housing permit it to be mo
unted
horizontally or vertically. Wires can exit from th
e side or the
breakout on the back of the housing. To enable tam
per protection,
set DIP Switch 8 to OFF and attach the tamper magne
t (provided)
(Figure 1) to the module inside cover. Be sure to
enable the
expansion zone tamper option at the control (progra
m field
\
24 =
0). If the module’s cover is removed, the magnet a
ttached 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, t
he 4208U
should be mounted horizontally and does not need ta
mper
protection, provided the cabinet is supervised. In
sert 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.
WIRING
C
E

For CE installations ADEMCO N6361 EMI suppression
bead is required. Refer to the N6361 Installation
Instructions for wire routing instructions.

Polling loop and protection loop wires can be broug
ht in either
through the back or front of the unit by removing t
he knockouts.
Use 22 gauge twisted pair wire for polling loop con
nections. All
protection loops use 10k EOL resistors (included).
A maximum
resistance of 300 ohms is allowed on protection loo
ps (excluding
EOLR). See Figure 2 for all connections.
Keep in mind that connections to the polling loop a
re always
required, while power supply connections are option
al.


1. INSERT BOTTOM TABS FIRST.
2. ENGAGE TOP WITH CLIP.

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 z
one numbers of
the control) and you do not lose zone numbers if yo
u 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 th
e 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.

Set the DIP switches on the 4208U as instructed bel
ow (see
Figure 3):
1. Select fast/slow response for loops A and B usin
g DIP Switch
1: Fast = OFF (10msec) Slow = ON (400msec).
2. Select mode of operation (serial number or zone
assignment
mode) using DIP Switch 6: Serial Number mode = ON;
Zone
Assignment mode = OFF.
3. Select the group setting using DIP Switches 2, 3
, 4, and 5.
See Table 1 for zone assignments or Table 2 for ser
ial
number assignments. If using more than one 4208U,
be sure
to set each one to a different group setting.
4. DIP Switch 7: Set DIP Switch 7 to “OFF”.
5. Select the 4208U Tamper Protection setting using
DIP Switch
8: Tamper Disabled = ON Tamper Enabled = OFF. Tam
per
will report for every active zone on the 4208U modu
le.
PROGRAMMING
When setting the 4208U to a group of zone numbers,
each zone
must be programmed as follows:
•

On ADEMCO 4140XMP and earlier controls, these zone
s
must be programmed as Left Loop Polling Loop Zones.

•

On ADEMCO VISTA-40 and later controls, these zones
must
be programmed in the #93 Menu Mode Zone Programming
as
INPUT TYPE “7” -- DIP Switch type polling dev
ice (DP).
When setting the 4208U to a group of serial numbers
, each zone
must be programmed as INPUT TYPE “6” --SL (Serial N
umber
Polling Loop Device). Loops can be learned in any
order and
assigned to any legitimate zone number.
When prompted to learn the serial number for a part
icular zone,
you may either enter it manually through the keypad
, through
COMPASS Downloader, or “learn” it by momentarily fa
ulting
(shorting) the terminals of that zone as required b
y the control. If
entering a serial number manually through the keypa
d, enter it and
press “
\
” to advance to the next prompt, which will ask you
for the
loop number. Entering a “1” for each serial number
entered.
If learning or entering a serial number, “Duplicate
of Zone XX”
Duplicate of Zone XX” is displayed; another device
with that same
serial number is already in the system. In that ca
se, use a
different serial number group setting on the 4208U.


!

If learning a serial number by faulting its
associated loop, make sure that other V-Plex
devices are no
t activated, as they may interfere
with the device being learned.

VERIFICATION OF PROGRAMMING
To verify proper programming, the following test sh
ould be
performed:
1. Be sure to enable expansion zone tamper protecti
on at the
control (program field
\
24 = 0).
2. Set DIP Switch 8 to OFF (tamper enabled).
3. Replace the 4208U cover and clear the keypad of
any faulted
zones.
4. Remove the 4208U’s cover and verify (on the keyp
ad) that
only the zones you designated for this 4208U are in
dicating a
check (or trouble) condition.

TO THE INSTALLER
Regular maintenance and inspection (at least annual
ly) by the installer and frequent testing by the us
er are vital to continuous satisfactory operation o
f
any alarm system. The installer should assume the
responsibility of developing and offering a regular
maintenance program to the user, as well as
acquainting the user with the proper operation and
limitations of the alarm system and its component p
arts. Recommendations must be included for a
specific program of frequent testing (at least week
ly) to insure the system’s operation at all times.

FEDERAL COMMUNICATIONS COMMISSION STATEMENTS
The user shall not make any changes or modification
s to the equipment unless authorized by the Install
ation Instructions or User's
Manual. Unauthorized changes or modifications could
void the user's authority to operate the equipment
.
FCC CLASS B STATEMENT
This equipment has been tested to FCC requirements
and has been found acceptable for use. The FCC requ
ires the following
statement for your information:
This equipment generates and uses radio frequency e
nergy and if not installed and used properly, that
is, in strict accordance with the
manufacturer's instructions, may cause interference
to radio and television reception. It has been typ
e tested and found to comply with
the limits for a Class B computing device in accord
ance with the specifications in Part 15 of FCC Rule
s, which are designed to provide
reasonable protection against such interference in
a residential installation. However, there is no gu
arantee that interference will not
occur in a particular installation. If this equipme
nt does cause interference to radio or television r
eception, which can be determined by
turning the equipment off and on, the user is encou
raged to try to correct the interference by one or
more of the following measures:
• If using an indoor antenna, have a quality outdoo
r antenna installed.
• Reorient the receiving antenna until interference
is reduced or eliminated.
• Move the radio or television receiver away from t
he receiver/control.
• Move the antenna leads away from any wire runs to
the receiver/control.
• Plug the receiver/control into a different outlet
so that it and the radio or television receiver ar
e on different branch circuits.
• Consult the dealer or an experienced radio/TV tec
hnician for help.
