STS Sprenger Outdoor alarm clock WK 973 ASR integrated

Specifically designed for use with small PBX systems or DSL routers with analog telephone connections, where the previous WK978 does not ring loudly enough. The AC outdoor bell WK 973 is an additional weatherproof electromechanical signaling device. It is intended for supplementary signaling in both private and industrial settings. Due to its low switching threshold and the low power consumption of the integrated relay, the WK 973 is well-suited for operation with small PBX systems or DSL routers with analog telephone connections.

The WK 973 can also be operated in parallel with already connected devices and has minimal impact on the a/b port. However, an additional power connection for the bell is required, making this additional bell several decibels louder compared to the WK978.
