Resetting the Alarm Signal

Pressing the "ALARM RESET" button resets an alarm that occurred in the past
(flashing green LED).
If the alarm status is still active, pressing the "ALARM RESET" button resets the
acoustic alarm and the relevant relay (1 and/or 2). The sensor LEDs remain
lit/continue to flash.
If the DIP switch "Repeat alarm in 24 hours" is set to ON (see chapter 4.1), the
alarm is repeated after 24 hours.
