ADEMCO 5881EN Series

RF Receiver

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 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 
installations. 

 

• 

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). 

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. 

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. 

j.  Insert the receiver’s antennas through the top of the cabinet, 

into the blocks’ right-hand terminals, and tighten the 
screws. 

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.
