The HGW signalling hooter is a signalling device for warning and calling which, thanks to its sturdy housing, can be used indoor in both dry and damp rooms as well as outside. The seawater-proof aluminium housing makes the device also suitable for use on ships as well.

The driver system consists of a strong, non-polarised electromagnet. The housing is made of seawater-proof aluminium. The signalling hooter is available for all usual supply voltages. The version HGWR 11 for 230 VAC is equipped with an additional telephone call relay. Cable entry is effected via an M 20 gland. The hooter with call relay has two cable glands.
