Signal Strength Test

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” in Hub settings).

👉🏻 Devices → [DEVICE] → Settings (⚙️) → Signal Strength Test

The test allows determining signal strength and stability in the supposed installation place.

In the test mode, the device exchanges data with the hub in real time, reflecting the current signal strength in the Ajax application and simultaneously by means of the LED on the body. Device test time at the installation place: minimum 1 min.

It is not mandatory to perform the test until the end. The test is needed to determine the optimal installation place with stable and high signal strength. 

Communication Level

Device Indication

3 signal bars — (Excellent)
Lights up almost continuously with a short interruption once in 1.5 s.
2 signal bars — (Satisfactory)
Blinks 5 times per second (blinks quickly)
1 signal bar — (Poor)        
Blinks 2 times per second (blinks slowly)
0 signal bars — (No connection)          
Quick flashes once in 1.5 s.


It is recommended to install the device in a location with 2–3 signal bars.

⚠️ With one bar of signal strength, we cannot guarantee stable operation of the security system. Take the necessary measures to improve the signal quality! At the very least, move the device — relocation even by 20 cm might significantly improve the reception quality.
