The 5881EH is an enhanced version of 5881H. See bulleted
paragraph in INTRODUCTION section.
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
via the remote keypad connection points .
The receiver recog nizes 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 con trol can provide redundant coverage or
extend coverage in large areas.
Multiple receivers do not
increase the number of transmitters that the system can
support. See the QED control's instructions for specific
information regarding the number and type of receivers that
can be supported.
These receivers feature a Spatial Diversity System which
virtually elimi nates the possibility of "Nulls" and "Dead Spots"
within the coverage area.
• The 4281/4281CN family of receivers are used in
conjunction with 5700 series transmitters.
• The 5881/5882 family of receivers are used in conjunction
with QED 5800 series transmitters.
• The 5881EH is an enhanced version of the 5881H using
Ademco’s new SignalSentry™ technology, and is intended
for use in commercial fire installations. To comply with
commercial fire applications, the 5881EH can only be used
with control panels that are approved for use in commercial
fire installations.
Note:
You will find identification of the receiver model on the
unit’s PC board (see Diagram 2 for location).
Each receiver supports the number of zones shown below.
4281L/4281CN-L
Up to 4 zones
4281M/4281CN-M
Up to 8 zones
4281H/4281CN-H
*See below
5881L/5882L
Up to 8 zones
5881M/5882M
Up to 16 zones
5881H/5881EH/5882H
*See below
*
The number of zones that the 4281H,
5881H/5881EH or 5882H receiver can support
depends on the QED control with which it is used.
See the QED control panel’s instructions for
specific details.
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
short (black) mounting clips (provided with the
receiver) on the raised cabinet tabs in the cabinet, as
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
long (red) clips at the
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 terminal of one of the antenna blocks (at the
upper edge of the receiver's circuit board). Secure it to
the cabinet with one of the two screws provided. See
Detail D.
