CROUSE-HINDS SERIES FHF communication Ex Howl-Call Telephones Battery and network-independent telephone system for applications under rough conditions, even in potentially explosive or firedamp-endangered areas Overview If you want or need to use a telephone where this is normally not possible, you need a telephone system that works according to the dynamic principle. Without any external power supply or complex equipment. In blast furnace areas, in tunnel building or mining areas, offshore, on an oil rig or a deep-sea vessel – in any place that is not (yet) connected to any energy source, the dynamic telephony represents an ideal opportunity for connection. To the switchboard, to the base station, to the bridge or colleagues above ground or wherever. This surprisingly easy but efficient method is already being used in many industrial areas to order material or report malfunctions and, not least, in many cases of work accidents it has already been useful to quickly call for help. The howl call telephone is a battery-free and networkindependent telephone with highly efficient dynamic trans mitter and receiver capsules offering remote communication without power supply. The call signal is generated by turning the rotary knob containing an audio frequency dynamo. All telephones have a sturdy, impact-resistant and weather proof housing. For years they have proven to be a reliable choice for the mining and tunnel building sectors, at construction sites and for industrial applications. The range is about 10 km.

Or, even easier, just prick into our flat-band cable, and the line is established. Our handsets and telephone systems are explosion-proof and equipped with a high-volume howl capsule, so that they even meet the require ments for the rough and noisy conditions in underground applications. Intrinsically safe telephony by FHF – for more independence and safety. To establish a dynamic telephone system, only two capsules are necessary. A supply with electric voltage is not required. The two capsules must be connected via a two-wire cable. Used as a microphone, the dynamic capsule generates a relatively high voltage from a low sound pressure. It is high enough to also generate a sufficient sound pressure for the other capsule used as receiver. The two capsules are interchangeable and can both be used as microphone or receiver. These are the main advantages: • simple design • quick Installation for frequently changing application sites • lightweight mobile devices • independent from network and battery • constantly ready for operation • reduced work load on existing branch exchanges • cost-effective Different versions: The right type for every purpose Type 5077 Prick pincer Type 5220 Intrinsically safe wall-mounted telephone with howl call generator Type 5069 Telephone with howl call generator Type 5564 Wall socket A manually operated electromagnetic call generator generates a wobble current with a frequency of approximately 2000 Hz, which is directly transmitted to the receiver capsule via a two-wire cable. The current has the effect that an acoustic wobble call is transmitted through the transmitter capsule‘s membrane. Application examples of howl call telephones 1.
