When option RINGON is used preconfigured number (by ALARM command) is
called within 30 seconds. No new alert is generated within 60 seconds after
alarm was detected. This option is ideal for PIR sensors which cause change of

which stay in switched logical 1 value. In this case alarm event is repeated until
ALARMOFF command is sent.
