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.
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 short (black) mounting clips (provided with
the receiver) on the raised cabinet tabs in the cabinet,
as shown in Detail B of Figure 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.
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.
