INTRODUCTION
The 4281/4281CN and 5881/5882 family of RF receivers are
designed for use with QED control panels that support an RF
receiver connection
The receiver recognizes alarm, status and keypad control
messages from wireless transmitters operating at 345MHz (in
Canada, 315MHz for 4281CN series).
For brevity, the various versions of these receivers are referred
to herein as "receiver" unless otherwise noted.
One or two individually identified receivers can be employed,
depending on the control used. Connection of multiple
receivers to a QED control can provide redundant coverage or
extend coverage in large areas.

These receivers feature a Spatial Diversity System which

If a receiver is connected to a system in which more than the
permitted number of wireless zones have been programmed, a
"SET UP ERROR" message (Alpha keypads) or an "E4 or
“E8”" message (fixed-word keypads) will be displayed on the
system's keypad, and none of the zones will be protected.
The instruction manual that accompanies the QED control
includes recommendations regarding receiver and transmitter
locations, the types of wireless zones that can be programmed
(e.g. ENTRY/EXIT, PERIMETER, INTERIOR, etc.) and the
procedure for programming the receivers.
These receivers should not be installed in an area subject to
environmental extremes of below freezing (such as an
unheated warehouse) or extremely high temperatures (such as
an attic).
.
INSTALLATION
With some QED controls, a receiver may be mounted directly
inside the control's cabinet (receiver circuit board only, without
its plastic housing) instead of remotely (in its own housing). In
both cases, avoid mounting the receiver antennas against a
metal surface.
Using The 5881EH In Commercial Fire Applications
The 5881EH must be mounted in a separate cabinet for
commercial fire applications. Refer to step 4.
1. Remove the receiver's cover by inserting and twisting a
screwdriver blade in the slot at the center of the cover's
lower edge.
2. If the receiver is to be mounted within the control's
cabinet (refer to Diagram 1):
a. Remove the receiver's circuit board from its base by
bending back the two flexible plastic tabs that hold the
board's lower edge.
b. In the control's cabinet, unfasten and move the control
circuit board downward (if already installed).
c. Hang two

shown in Detail B of Diagram 1.
d. Insert the top of the receiver board into the supporting
slots provided at the top of the cabinet, as shown in
Detail A. Swing the bottom of the receiver board into
the two short (black) mounting clips installed in step c,
and secure it to the cabinet with the accompanying
screws. See Detail B.
e. Insert the top of the control’s board into the slot in the
black clips holding the lower edge of the receiver board
(see Detail B), and position two
lower edge of the board (see Detail C).
f. Swing the lower edge of the control board into place,
and secure with two additional screws.
g. Insert one of the two grounding lugs (provided with the
receiver) through the top of the cabinet and into the
left-hand
upper edge of the receiver's circuit board). Secure it to
the cabinet with one of the two screws provided. See

h. Do the same with the other ground lug and antenna
block.
i. Insert the receiver’s two antennas through the two
openings in the top of the cabinet, one into each block’s
right-hand terminal, and tighten the screws to secure
them.
j. Affix the receiver's Summary of Connections label to the
inside of the control's cabinet door.
k. Discard the receiver's unused plastic cover and base.
3. If the receiver is to be located remotely from the
control in its own plastic enclosure (not in a cabinet):
The circuit board mounting clips, grounding lugs and screws
included with the receiver will not be needed.
a. If concealed wiring is to be used, route it through the
rectangular opening at the rear of the base before
mounting. For surface wiring entry, a thin breakaway
area is provided along the base's right edge.
b. Mount the receiver in the selected location. For greatest
security, use all four mounting holes (two keyslot holes
and two round holes) provided in the plastic base.
c Affix the receiver's Summary of Connections label to the
inside of the housing cover.
4. Mounting the 5881EH in a Separate Cabinet For
Commercial Fire Applications.
For commercial fire applications, the 5881EH must be
mounted in a separate cabinet,

farther than 20 feet from the alarm control cabinet., with no
intervening walls or barriers):
a. Remove the receiver's cover by inserting and twisting a
screwdriver blade in the slot at the center of the cover's
lower edge.
b. Remove the receiver's circuit board from its base by
bending back the two flexible plastic tabs that hold the
board's lower edge.
c. Mount the receiver board in the cabinet as follows:
Insert the top of the receiver board into the supporting
slots provided at the top of the cabinet (see Diagram 1
and Detail A which show how the top of the receiver
board is secured).
Secure the bottom of the receiver board with 2 screws
(not supplied) using
head of each mounting screw and the PC board.
d. Affix the receiver's Summary of Connections label to the
inside of the cabinet door.
e. Discard the receiver's unused plastic cover and base.

For commercial fire applications, DIP switch #5 MUST be
in the ON position.
Note: All other system components, including the
control, must be approved for use in commercial
fire applications.
When the 5881EH is not used in a commercial fire
application, switch #5 should be placed in the OFF
position.
6. Insert the wiring plug (with 4 flying leads) into the
mating socket on the receiver (see Diagram 2 for socket
location). Connect the 4 wires to the control's corresponding
remote keypad connection points (see “Interface Wiring” in

7. Install the antennas in the
terminal blocks at the upper edge of the circuit board, one
into each block’s right-hand terminal, and tighten the screws
to secure them.
If the receiver is mounted in a cabinet, insert the antennas
through the holes in the cabinet's top first, and then into the
terminal blocks.

8. Replace the receiver's cover if the receiver is not mounted
within a cabinet.
9. Proceed with any programming of the control that may
be necessary for RF operation, and the installation of
the system's wire less transmitters, as described in the
QED control's installation instructions.

TO THE INSTALLER
Regular maintenance and inspection (at least annually) by the installer and frequent testing
by the user are vital to continuous satisfactory operation of 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 parts. Recommendations must be
included for a specific program of frequent testing (at least weekly) to insure the system's
operation at all times.

which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or
more of the following measures:
• If using an indoor antenna, have a quality outdoor antenna installed.
• Reorient the receiving antenna until interference is reduced or eliminated.
• Move the radio or television receiver away from the 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 are on different branch circuits.
If necessary, the user should consult the dealer or an experienced radio/television technician for additional suggestions. The user
or installer may find the following booklet prepared by the Federal Communications Commission helpful:
