The EEx Sounder dEV 21 is a signalling device that generates various signalling tones and signalling tone sequences and emits them at a high sound pressure level. The user may choose between 31 preset signalling tone groups and one programmable one. Every signalling tone group contains 4 different signalling tones. Wire the control inputs with floating contacts or jumpers in order to chose any one of these 4 signalling tones. The sounder has 8 volume levels. All outer fastening parts are made of non-corrosive materials. The stable, all-plastic housing conforms to protection degree IP 66, which means the sounder can be installed both indoors and outdoors. Explosion category II 2 G EEx dem IIC T6 allows the sounder to be operated in hazardous areas of zones 1 and 2.

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.

Design experts honour Flash Multi-tone Sounder with red dot award
In one of the most fiercely contested international design competitions, the red dot design award, WERMA Signaltechnik’s Flash Multi-tone Sounder 444 was selected for an “honourable mention”. The award winning signal device clearly stood out from the mass of 3,200 products from over 49 countries submitted to the competition.
Attractive Flash Multi-tone Sounder 444
With its honourable mention, the distinguished jury panel honours products that excel thanks to their highly successful design solutions. The award winning flash multi-tone sounder 444 is user friendly and visually appealing.
Diagonal lines and round forms conjure a slim appearance which harmoniously blends into the environment. It is equipped with a horn that merges seamlessly into the light window, enabling the LED double flash to propagate to the maximum. At the same time the siren generates a formidable sound output for its size of 114 dB.
Robust material, energy-saving LEDs and optimised production techniques make the flash multi-tone sounder a maintenance-free and environmentally friendly product. Thanks to its signal strength, it is especially suited for use on machines, buildings or fire alarm systems.

The DB5 intrinsically safe multitone sounder is ideally suited for use in areas of high ambient noise. Additionally, for extreme noise levels, they can be linked with the DA134 Xenon Beacons to combine audible and visual warnings. They are designed with a re-entrant configuration to combine compactness with maximum efficiency.
One of 26 tones can be selected using a 5-way DIL switch and by switching the incoming negative supply to a third terminal a second tone is sounded. The sounders have suitable low frequencies to conform to BS 5839: Part 1: 1988, making them ideal for fire alarm systems and other annunciator applications.
The IP65 enclosure enables the DB5 sounder to cope with the harsh environmental conditions found offshore as well as those of the onshore oil, gas and chemical industries. The tough construction enhances the reliability of the solid-state piezoelectric sounder.
