22. GSM CONNECTION AND ANTENNA STATUS MONITORING
22.1. GSM Connection Status Monitoring
The system supervises the GSM connection every 10 minutes. When the GSM connection loss is detected, the system indicator NETW will
light OFF and the system will attempt to restore the GSM connection. In case the system fails to restore the GSM connection within a 3-min-
ute period (by default), the keypad will indicate the system fault condition (see 29. INDICATION OF SYSTEM FAULTS) and the system will
continue the attempt to restore the GSM connection. In addition, the system may turn ON a determined PGM output to indicate the GSM
connection loss fault (by default - disabled).
Once the GSM signal restores, the system may notify the listed user by SMS text message (by default - disabled), the keypad will no longer
indicate system fault and the determined PGM output will turn OFF (if set up).
By default, the notications by SMS text message regarding GSM signal loss is disabled. To enable/disable this notication, please refer to
the following conguration methods.
