The 5881EN Series of RF receivers is designed for use with control
panels that support an RF receiver connection via the keypad
terminals. The receiver recognizes alarm, status, and keypad
control messages from wireless transmitters operating at 345MHz.
One or two individually identified receivers can be employed,
depending on the control used. Connection of multiple receivers to a
control can provide redundant coverage or extend coverage in large
These receivers feature a Spatial Diversity System that virtually
eliminates the possibility of "nulls" and "dead spots" within the
coverage area. The 5881EN series of receivers use ADEMCO's High
Security technology, and can be used in commercial fire
installations. Additionally, the 5881ENHC receiver contains front
and back tamper that permits its use in commercial burglary and
For 5881ENHC Receivers:
In commercial fire applications, the receiver can only be
used with control panels that are approved for use in
Commercial Fire Installations. When the 5881ENHC is
used in commercial fire applications, DIP switch 5 must
be in the ON position.
In commercial burglary applications, the 5881ENHC can
only be used with control panels that are approved for
use in Commercial Burglary Installations.
In commercial fire applications, a keypad must be
connected to Keypad Port 2 in the control. The keypad
must be mounted on the control or within 3 feet of the
control with the wiring encased in conduit.
• All power-limited wiring must be separated from non-
power limited and high-voltage wiring by ¼" (6.4mm).
Each receiver supports the number of zones shown below.
* The number of zones that the 5881ENH receiver can support
depends on the control with which it is used. See the 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 (on alpha keypads) or an "E4 or "E8""
message (on 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 control includes
recommendations regarding receiver and transmitter locations, the
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).
With some 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.

NOTE: You may only mount the 5881ENHC its own plastic
housing. If you attempt to mount the 5881ENHC in the control's
cabinet, the receiver constantly reports a tamper condition.
1. Remove the receiver's cover by inserting 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 Figure 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
b. In the control's cabinet, unfasten and move the control
circuit board downward (if already installed).
c. Hang two mounting clips (provided with the receiver) on the
raised cabinet tabs, as shown in Detail B of Figure 1.
d. Insert the top of the receiver board between the rows of slots
at the top of the cabinet, as shown in Detail A.
e. Position the base of the receiver board onto the mounting
clips and secure to the cabinet with the supplied screws. See
f. Hang two mounting clips (supplied with the control board),
on the raised cabinet tabs as shown in Detail C in Figure 1.
g. Insert the top of the control board into the slots of the
mounting clips secured in step e above.
h. Position the lower end of the control board into place on the
mounting clips and secure both to the cabinet with the two
i. Insert both grounding lugs (supplied with the receiver)
through the top of the cabinet into the left-hand terminals of
the antenna blocks (located on the upper edge of the receiver
board), and secure them to the cabinet with the screws
provided, as shown in Detail D.
j. Insert the receiver's antennas through the top of the cabinet,
into the blocks' right-hand terminals, and tighten the
k. Affix the receiver's Summary of Connections label to the
inside of the control's cabinet door.
l. 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):
You will not need the circuit board mounting clips, grounding
lugs and screws included with the receiver.
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 key slot holes and
two round holes) provided in the plastic base.
c. If installing a 5881ENHC, install a flat-head screw
(supplied) in the case tamper tab as shown in Figure 2.
When the receiver is pried from the wall, the tamper tab will
break off and remain on the wall. This will activate a tamper
switch in the receiver and cause generation of a tamper
signal. Note that this signal will also be generated when the
receiver's front cover is removed.
d. Affix the receiver's Summary of Connections label to the
inside of the housing cover.
