800Hz Construction Elevator Intercom Multiple Frequency Selection

Intercom System for Building Hoist with Multiple Frequency Selection and Compatible with Your Old Hoistcoms

The intercom system is mainly designed for the building hoist and industrial elevator, which provides a communication line between the building floors and building hoist operator,and it could also be used as general communication method in other industries.

Because the radio frequency does not need to apply from local authority, the intercom system can be used in the sites of many building hoists, which will not affect each other. With reliable communication, the working efficiency of the building sites can be greatly increased and chance of accidents can be reduced.

Features:

1. The signal transmission is through the earthing line of the building hoist’s power system, which ensures a stable & reliable signal transmission and saves the needs of special communication cable.

2. There is no high voltage connection between the signal line and the power line, which is safe from electrical hazards

3. There is no electromagnetic wave pollution with this system, so no need to apply for radio frequency control, and even

being used in the building hoists intensive areas, it will not affect each other’s performance.

4. The intercom system is easy to use, by pressing the “SPEAK” button, workers at different floors can directly talk to the

operator of the building hoist. And it has the functions to show the line is busy and lower the noise from the surroundings.

ensure a clear communication.

The cover adopts imported high strength nylon materials, which is fatigue resistant, anti-conrrosive and nonflamable.

The chip is of Philips brand, with strong & high penetrating signals.

The speaker adopts voice compresion-expandor technology, which can minimize the ambient noises and ensure a smooth & clear communcation at the construction site.
