Setting the GSM Gateway to generate the Dial tone battery alarm, indicating a battery failure. When a
battery failure occurs the Gateway will send a congested tone instead of the normal continuous dial
tone. The Dial tone battery alarm is 1000ms ON / 250ms OFF / 250ms ON / 250ms OFF. To configure
this setting set:
“Dial/Congestion tone, battery fault” to “Dial tone battery alarm”.
This setting is default active.
The emergency alarm must be programmed accordingly in order to detect the battery fault alarm
signal from the Gateway; please see the manual for the emergency alarm if that setting is available.
