The signalling bell dGW21 was designed to warn, call and signal in areas with explosive atmospheres in group II and rough ambient conditions.

The protection type II 2G Ex de IIC T6 allows the signalling bell to be used without restriction in all ex-areas classified 1 and 2.

The signalling bell produces a sound volume of approx. 105dB(A) at 1m distance.

The emphasis of the ringing lies at approx. 1000 Hz, as a result of which the signal stands out clearly against lower-frequency ambient noises.

The bell is available for all usual supply voltages.

The version dRGW 21 emits the signals in time with the connected telephone call.

Can be used in:
II 2G Ex de IIC T6 Gb
Zones 1, 2.
