Advanced communications system for potentially explosive areas

01 March 2008

Improved communications technology improves worker safety; there are fewer accidents caused by a lack of or poor communications. The work process is accelerated through better co-ordination and consultation. Fewer accidents and blunders reduce the costs of repairing and maintaining expensive machines and systems.

The headset has been constructed to prevent unacceptable electrostatic charge

The world’s first ATEX explosion-proof digital wireless device integrated into a heavy-duty headset is now available from CeoTronics. It enables full-duplex digital communications for up to five mobile subscribers in potentially explosive environments and has a range of up to 150m, depending on local conditions. Channel selection is done automatically via the headsets. DECT technology guarantees secure, interference-free communications. Maximum transmit power is a safe level of 500 mW.

Duplex communications are possible for up to five mobile subscribers per group in an ATEX environment with the CT-DECT headsets – without the need for PTT. Both hands are always free to perform the actual
task. All co-workers are accessible at all times and can call for help or pass on important information when it’s needed, not just when the transmitter channel is unoccupied – when it could be too late. Target groups for the intrinsically safe CTDECT Headset/Ex are the chemical and petrochemical industries, power plants, oil platforms and production facilities, pipeline inspection teams, crews on oil and gas transportation ships, and plant fire fighting teams.

The headset provides protection from harmful noise in the surroundings while enabling communications in noisy environments. It can be ordered in behind-the-neck/over-the head variants and versions with helmet adapters. The headset is equipped with either a noise-cancelling boom microphone with windscreen or a
throat microphone.

Integration of digital noise reduction allows for communications even in extremely noisy areas. The CT-DECT Headset/Ex is designed for ATEX as an intrinsically safe device in accordance with European standards EN 60079 and corresponds to protection class II 2 G Ex ib IIB T4.

The headset is largely made of nonconductive plastic. It has been constructed to prevent unacceptable
electrostatic charging when used as intended (gas group IIB). Easily replaceable rechargeable battery in ear cup for 10 hours of continuous operation. Power is supplied via a lithium-polymer rechargeable battery
permanently mounted in the right ear cup and enabling around 10 hours of continuous operation. The cup battery can be replaced via the plug connector, cutting downtime to a minimum.
