Call attempt error
▸ The relay is activated if the current relay is in standby mode.
▸ The relay is deactivated if triggering an alarm fails. If a fallback alarm is active, both switching
paths are down. If the rescue is successful (emergency call end), the relay closes.
Automatic test of the emergency call button
▸ To test the emergency call button, the relay is activated once a day.
▸ The relay is deactivated if the input signal at the emergency call button changes or if a DB collec-
tive fault message is programmed at an output.
14. FALLBACK FUNCTION
With the fallback function (parameter *93*),
both the landline (PSTN) and the radio network
(GSM or LTE) can be used for emergency calls.
If you set one network as default, the other will
act as a fallback network in case the default network is not available (both the telephone
line and the SIM card must be enabled for the
function). Incoming calls are handled by both
ports, but they are not used simultaneously.
