If any motion is detected, the detector activates the LED for 1 second and transmits an alarm
signal to the hub and then to the user and central monitoring station (if it is connected).

Detector Testing
The Ajax security system allows conducting tests for checking the functionality of connected
devices.
The tests do not start straight away but within a period of 36 seconds when using the standard
settings. The test time start depends on the settings of the detector scanning period (the
paragraph on “Jeweller” settings in Hub settings).
Signal Strength Test
Detection Zone Test
Attenuation test
Selection of the Detector Location
The area of the controlled territory and, consequently, the efficiency of the security system
depends on the location of the detector.
Location of the Ajax MotionProtect detector determines its remoteness from the hub and
presence of any obstacles between the devices hindering the radio signal transmission: walls,
inserted floors, large-size objects located within the room.
⚠️Check the signal level at the installation location
If the signal level is one division, we cannot guarantee stable operation of the security system.
Take possible measures to improve the quality of the signal! As a minimum, move the device -
even 20 cm shift can significantly improve the quality of reception.
