The alarm system can be put in a testing mode. This will cause the alarm to beep three times when receiving a signal from a sensor which is triggered, instead of ringing the siren.
The test mode can be started by sending “100” to the SIM card phone number which is inserted in the control panel. After 10 minutes the system will automatically stop the test mode.
It is also possible to stop the test mode by pressing the [SOS] button on the control panel.
