The DUO signals incoming calls both audibly and optically. The flash frequency and the signal tone can be set individually. The extensive settings can be configured via web-interface. The DUO / SIP is intended for wall mounting and is controlled by the integrated SIP telephone connecting relay. Power supply is via PoE or extern with 48V.

The DUO signals incoming calls both audibly and optically. The flash frequency and the signal tone can be set individually. Breaks in the ringing current are bridgeable. The DUO/LED is intended for wall mounting and is controlled by the integrated telephone connecting relay. Other connecting types are possible, such as via a doorbell.

The line powered high output unit has been designed for installation in large offices or factory areas with high ambient noise levels, and replaces the traditional mains voltage bell. The unit is rated to IP66 and is therefore capable of operating in adverse conditions. The Bedlam Loud Tone Caller is designed to replace the traditional mains powered bell and is powered by the PABX and PSTN line voltage (60-100 volts AC). A variable output (85-105dBA) is possible by means of a potentiometer located within the unit.

The Bedlam Loud Tone Caller – for interior and exterior use, up to 105dBA output, requires cabling to PST system. Measures approx. 120mm x 92mm x 114mm (including cable entry gland), weight 420 grams. Requires 4 No. 10 round-head, rust-resistant screws. Cable entry gland may be removed to provide 20mm conduit entry.

The volume control of the Bedlam Loud Tone Caller is normally supplied set to maximum (clockwise) and may be adjusted on installation if customer or situation require otherwise. If the volume control of the Bedlam Loud Tone Caller is left set to maximum volume it must not be mounted within 3 Meters of persons using the area. Access to the volume adjuster is via the four body fixing screws. The adjuster is in the base of the warbler unit.

The Bedlam Loud Tone Caller emits a loud piercing tone and must be fitted where it cannot cause acoustic shock. Cabling should be disconnected at distant end before approaching a Mayhem  tone caller on installation or maintenance visits.

The explosion-proof secondary telephone bell is designed for indoor and outdoor applications in potentially explosive industrial areas, e.g in the petrochemical industry.
The high-quality materials have priorily been tested in our laboratory and allow for uses in extreme application areas of the Ex II industry.
The user may choose between single tone, 2-tone, 3-tone or warble-tone using the available DIP switches. Moreover, the tone sequence frequency can be set in four steps between 5 and 20Hz

The phone signal Ex-Duo signalizes incoming calls from stationary telephones as a secondary ringing device. The signaling is ensued by a 5 joules flash and by a 110 dB(A) sounder. Once an incoming call is signalized, the flash and the sounder will be activated. Between the ringing signals the flash is bridged for continuous flashing. Different sounds can be set individually.

The TW2 is built into a shock-proof plastic casing based on protection standard IP 66. The intermittent alarm has a maximum volume of 93 dB (A)/1 m. Because this is significantly different from running machines and motors, it can be perceived even in a loud environment.

The iHS headset will keep you in safe contact even in potentially explosive environments. Thanks to the headset’s excellent insulation efficiency, you can conduct smooth conversations even in environments with very high noise levels of up to 115 dB (A). The dynamic microphone perfectly compensates for disruptive external noises. The iHS perfectly complements the dA24 industrial telephone and is suitable for use on offshore platforms and other explosive environments. With the connection Relay you can switch different appliances in modern SIP- and IP- networks.

Even in the midst of high noise levels of up to 115 dB, the WHA allows you to conduct comprehensible conversations, since the dynamic microphone compensates for external static noise. Given its robust construction, the WHA is particularly well suited for industrial use. It is designed for extreme conditions in terms of heat, cold and moisture – such as within a deep-freeze facility or ship machine rooms.

The intrinsically safe Ex Secondary Receiver Set is used for connection to the explosion-proof telephones ExResistTel and ExResistTel MB.
The receiver enables a third person to take part in the telephone conversation. Moreover, it can be used to reduce disturbing environmental noises during a telephone call.
The Headset may be connected to all explosion-proof telephones from the ExResistTel line to improve communication in noisy environments, protect the user from harmful environmental noise and enable telephone calls while carrying out tasks that require the use of both hands.
The Ex Headset and Ex Secondary Receiver Set both include mounting brackets as well as the required screws and cable glands for an installation at the telephone.

The TA3 and dTA3 telephone connection relay can be used to switch up to two external devices separately with ring tone signals – such as a siren and a flashing light.
The bridging of the calling pause can be set for each of the attached devices. Both the TA3 and the dTA3 are designed for permanent use and are suitable in their weatherproof forms for temperatures between -20 ˚C and + 60 ˚C; in the Ex variation between -20 ˚C and + 40 ˚C.

With the connection Relay you can switch different appliances in modern SIP- and IP- networks. Especially user-optimized is the set up with the web interface. Power is supplied via PoE or externally with 48V. Moreover the IP-version combined with our VoIP-telephone can be operated without an extra SIP-account. There are 3 options for comfortable controlling of the IP-version. It can be easily controlled via the web browser, a windows program or automated via a windows command line batch.
