INSTALLATION AND SETUP GUIDE 

 

 

 

TYPICAL INSTALLATION  

 

GENERAL INFORMATION 

The 5818 Recessed Door Transmitter is a 
reed switch, magnetic-contact sensor that 
provides concealed protection for a door. 
It is intended for use only with alarm 
systems that support 5800 series devices. 
The transmitter is powered by long-life 
lithium battery that is easily replaceable 
when a low battery is indicated by the 
control.

 

PROGRAMMING THE ID NUMBER 

Each 5818 has its own unique 
identification code (serial number) 
permanently assigned during manu-
facture. 
You must “enroll” the transmitter’s ID 
during installation of the alarm system. 
5818 transmitters must be enrolled as  
"RF" (supervised RF) Type (

mandatory for 

UL installations

). 

PRELIMINARY CONSIDERATIONS 
Read all of this and the next section 
before installing the unit. 

1. 

Select a location for the transmitter 

on the frame of the door (never on 
the hinged 
edge) to be protected.

 

• 

Do not use on metal frame doors. 

• 

The transmitter will require a 7/8“ 

diameter hole in the edge of the 
frame, at least 5” deep and its 
magnet will need a 1/2” diameter hole 
in the edge of the door at least 1-3/4” 
deep. 

 

 

BEFORE DRILLING ANY HOLES, SEE 
STEP 2 BELOW AND READ ALL 
OFMOUNTING
.

 

• 

The preferred direction of mounting is 

vertical, although the 5818 may be 
mounted in 

any

 direction if 

satisfactory reception of its 
transmissions is obtained. 

• 

A physical barrier (e.g., a molding 
strip on the door frame) should be 
present to protect against defeat of 
the contact from outside the 
premises.

 

2. 

Before drilling any holes, 

tape the 

transmitter and magnet in their 
approximate locations (with battery 
installed and unit together as described 
under BATTERY INSTALLATION/ 
REPLACEMENT (below) and conduct 
Go/No Go tests (refer to control panel’s 
instructions) to verify adequate signal 
strength. Reorient or relocate trans-
mitter if necessary.

 

• 

Make sure that 

no more than 1/2” 

gap exists

 between the faces of the 

transmitter and magnet cases when 
they are installed and set. 

• 

When installed, an alarm signal must 

be obtained 

before a clear space of 

2” is reached 

as the door is opened. 

 

MOUNTING 

1. 

Mark the selected location for the 
transmitter

 on the frame of the door.
