INTRODUCTION 
 
The Motion Detector is designed with two detecting 
sensors, Passive Infra-Red (PIR) sensor and light sensor, 
to detect movement within a protected area, operating at 
868.30/923 MHz only.   
 
The detector can be used as a security device or home 
automation device.    When the detector is cooperated with 
security appliances, the detector is acting as a security 
device by detecting changes in infra-red radiation levels.  
If a person moves within or across the devices field of 
vision, a trigger radio signal will be transmitted to cause full 
alarm condition in order to frighten intruders away. 
Alternatively, when the detector is worked with Everspring 
USB Dongle (SA804), the detector can be set to perform 
the role of home automation device by detecting both 
changes in infra-red radiation levels and percentage of lux 
levels.  Once night falls, the percentage of ambient 
illumination is lower than preset value.    If a person moves 
within or across the devices field of vision, a trigger radio 
signal will be transmitted so as to turn connected lightings 
for better illumination. 
   
Two mounting methods are provided for varying detection 
range.    The detector can be mounted on a wall for farther 
detecting distance but narrower coverage; while for ceiling 
mounting, shorter detecting distance can be made but 
desired coverage can be expected at user’s disposal. 
 
The Motion Detector is powered by 3 x AA 1.5V alkaline 
battery.  When battery level drops below unacceptable 
level, the red LED will flash once every 30 seconds and 
transmit radio signal to the control panel.  When this 
occurs, replace the batteries as soon as possible. 
 
CHOOSING A MOUNTING LOCATION 
 
The Motion Detector can be mounted either on a wall or 
under a ceiling.    Before selecting a position for a Motion 
Detector the following points should be noted:
 
 
 
1. 
Do not position the detector facing a 
window/fan/air-conditioner or direct sunlight.  Motion 
Detectors are not suitable for use in conservatories or 
draughty areas.   
 
2.  Do not position the detector directly above or facing 
any source of heat, e.g. fires, radiators, boiler etc. 
 
3.  Where possible, mount the detector so that the logical 
path of an intruder would cut across the fan pattern 
rather than directly towards the detector (FIGURE 1).

4.  For best results, position the detector directly facing 
entrance. 
 
5.  Ensure that the position selected for the Motion 
Detector is within effective range of the system (refer 
to System Installation and Operating Manual).   
 
INSTALLING THE MOTION DETECTOR 
 
The unit can apply two ways of installations.  Select a 
location for the unit based on the coverage angles shown 
in FIGURE 4b and FIGURE 5b. To install a detector: 
 
1.  Undo and remove the screw from the bottom edge of 
the detector to detach the rear cover (FIGURE 2).
