5881EN Series
RF Receiver
INSTALLATION AND SETUP GUIDE
INTRODUCTION
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 areas.
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 new Signal-Sentry™ 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
installations.
UL
•
In commercial fire applications, the receiver can
only be used with control panels that are approved
for use in Commercial Fire Installations. When the
5881EN 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.
Each receiver supports the number of zones shown below.
5881ENL
Up to 8 zones
5881ENM
Up to 16 zones
5881ENH
*See below
5881ENHC
*See 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 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 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 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 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 edge.
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 Detail B.
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 supplied screws.
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.
