How it works
DrainAlarm FIRST − mains-dependent alarm signal
A fill level is recorded via a float switch at the alarm input. If the fill level is reached, an acoustic alarm signal is triggered via the integrated buzzer. Further signalling can also take place via the two alarm outputs:
- Alarm output, not potential-free: Normally open contact
- To connect an alarm horn or light directly.
- Alarm output, potential-free: Changeover contact
- To connect external alarm signals or existing controls.
Alarms can be acknowledged directly via the buttons on the switchgear. Alternatively, you can also use an external button to acknowledge alarms.

- The alarm output is operated via the battery. If the mains connection fails, the alarm signal is maintained for approx. 60 minutes.
- Alarm output, potential-free: Changeover contact
- To connect external alarm signals or existing controls.
Alarms can be acknowledged directly via the buttons on the switchgear. Alternatively, you can also use an external button to acknowledge alarms.
Furthermore, the mains connection is monitored. If the mains connection fails, this is signalled visually (LEDs) and an acoustic alarm signal is triggered via the integrated buzzer.
