The loop driven sounder beacon base series is a loop driven device designed around a fully digital protocol.

The sounder beacon base is an acoustic output device which supports up to 32 tones ranging from a slow whoop, pulsed and continuous tone with synchronisation of both the sounder and beacon.

The device has four fixed volume levels ranging from 85 dB to a maximum of 92dB making the device suitable for almost any EN markets.

The low profile sounder is designed to comply with EN54 and requires
the 20-VPU1000-ADV hand
held programmer for volume and operating mode configuration.

The sounder beacon base provides a fast and secure response, and incorporates a bidirectional short circuit isolator.
