The EEx II signalling hooter dGH21was developed for warning, calling and indicating purposes in areas with explosive atmospheres in group II and for rough ambient conditions. Thanks to its compliance with the explosion protection class II 2G EEx de IIC T6, this signalling device can be used without restriction in all areas with explosive atmospheres in zones 1 and 2. The hooter produces a volume of appr.105dB(A) . The characteristic hooting sound can be clearly heard above any other higherfrequency sounds in the area. The dRGH21 comprises a telephone calling relay and reproduces the signals in the pulse rate of the overriding telephone call. The explosion protection is given through the flameproof chamber and the chamber “increased safety”. The flameproof chamber contains the electromagnetic drive system and, for the dRGH21, an additional telephone calling relay. The signal membrane is mounted outside of the flameproof room beneath a closing cap with the appropriate sound control. The housing is made of GRP thus guaranteeing protection against corrosion. Furthermore the construction is lowweight and highly robust. All DC versions are equipped with an electronic contact breaker which considerably increases service life compared with other commercially available devices.

The trumpet horn has been designed to provide an effective penetrating low frequency buzzer sound which is generated electronically, replacing the traditional electro-mechanical generator.
They produce an identical sound with the increased reliability of an all-electronic solution.
Features:
- Three version:
- H100T – electronic signal horn with trumpet flare – 100 dB(A) @ 1m
- H100B – electronic signal horn (without trumpet flare) – 100 dB(A) @1m
- H110T – electronic signal horn with trumpet flare – 110 dB(A) @1m
- Incorporated volume control
- IP65
- Three alarm sounds
- Also available in combination with xenon strobe, LED beacon and halogen rotating beacon (H110T only) to give visual reinforcement of the audible warning.

The HPW 11 signalling hooter is a signalling device for warning and calling which, thanks to its sturdy housing, can be used indoors in both dry and damp rooms as well as outside. The version with telephone call relay allows the device to be used as an additional, loud acoustic signalling device for a telephone. The driver system consists of a strong, non-polarised lectromagnet, whose striker hits the diaphragm between 100 and 120 times a second. The housing of the signalling hooter is made of impactresistant thermoplastic. A self-sealing grommet M20 is proveded as cable gland for cable diameters of 8 to 1 mm. The signalling hooter with telephone relay is equipped with two self-sealing grommets M20.
