Safety First: Mainly used on construction and temporary Hoists/Elevators, it is recommended by OSHA and considered the industry standard in the USA, Canada, and Australia.

Communication is critical to provide workers a way to contact the elevator operator in case of an emergency. When a worker is hurt, seconds count to get medical attention. As a general intercom system, it allows supervisors and workers to locate and communicate with each other, reducing downtime tremendously.

Key Features

  • All units interchangeable; no antenna wire required.
  • Two-way communications with volume-controlled Car Units.
  • Powered by safe 24 volts DC with multiple frequency channels.
  • Emergency alarm switches on all units.
  • Operates in extreme weather conditions.
  • Backup battery power supply for Car unit.
  • Heavy duty composite Nylon Plastic enclosure.
  • Up to 3 Multiple Frequency channels selection.
  • Microphone gain adjustment for feedback control.
  • Mute function to limit broadcast units.

Functional Performance

Stable Signal: Transmission is carried out using the protection loop line. The signal is stable and reliable, requiring no special communication cables.

Safe Operation: Signal and power lines are not connected with high voltage. No electromagnetic wave pollution; no need to apply for radio frequency, preventing interference in intensive construction areas.

User Friendly: Electronic volume control, alarm button for emergencies, and three available frequencies (250KHz, 741KHz, or 800KHz) for clear voice quality.

Frequently Asked Questions

Where is this intercom system typically used?
It is primarily used in industrial elevators of buildings and construction hoists to provide emergency communication between floors and the elevator driver.
Does the system require special radio frequency permits?
No, the system does not produce electromagnetic wave pollution and does not require a radio frequency application, making it ideal for intensive construction areas.
What should I do if there is a communication failure?
Check if the protective ground wire of the coupler is grounded in the middle, and ensure the protective earth wire and ground wire in the hanging basket are properly connected.
How far is the effective communication range?
The system supports an effective range of more than 300 meters, provided the conductor loop resistance is less than 600 ohms.
What power supply is required for installation?
The system operates on 220V AC or 110V AC supply voltage, while the units themselves are powered by a safe 24V DC.
How can I reduce interference from electric motors?
If interference occurs, ensure that the cables used have better shielding to protect the signal integrity.
