1. Introduction

The Red Shield Door/Window Sensor consists of two parts, a transmitter and a magnetic contact. Once this 

sensor is installed, with the transmitter fastened to the frame and the magnet to the door or window, the sensor 

will trigger and transmit a message to the Wire-free Protection System Smart Panel when the door or window is 

opened. 

2. Location

First determine the location of the Sensor, which should be placed:

• in the most vulnerable rooms or near key entry/exit points

• away from extreme temperature sources (radiators, ovens, stoves etc.) and large metal objects that could 

interfere with the wireless performance

• away from direct sunlight. 

• indoors only and not behind partitions

• where better RF performance can be achieved (if necessary)

3. Installation and Operation
3.1 Powering up the Door/Window Sensor

• Remove the battery cover; insert new batteries noting the polarity as 
shown in Fig.1 and replace cover. (Requires 2 x AAA batteries)
• Low battery indication: If the batteries need to be replaced, the RED LED 

on the transmitter will flash slowly.
