Specifically designed and manufactured to provide CRYSTAL CLEAR communications to help create a safer work environment, which increases PRODUCTIVITY and lowers the risk of LIABILITY.
Mainly used on construction and temporary Hoists/Elevators, it is recommended by OSHA, and also considered the industry standard. Communications 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.
Also acts as a general intercom system, allowing supervisors and workers to locate and communicate with each other, reducing down time tremendously and adding to project profit.

✔Signal transmission via protection loop line; stable and reliable without special communication cables.
✔No connection with high voltage, ensuring system safety.
✔No electromagnetic wave pollution; no need for radio frequency applications.
✔Electronic volume control and squelch function.
✔Three frequencies available for clear and natural voice.
Floor Installation: Connect the intercom with the accessory power cable. A dedicated power supply device can drive fewer than twenty units. The protective ground wire must pass through the coupler hole to the ground. Note: Do not ground the wire in the middle.
Lifting Cage Installation: Connect the intercom, power supply, and coupler in the lift cage. The protective ground wire must pass through the coupler hole and be connected with the ground.
Frequently Asked Questions
● What should I do if there is a communication failure?
Check if the protective ground wire of the coupler is grounded in the middle. Ensure the protective earth wire and the ground wire in the basket are properly connected.
● What causes poor communication quality?
Poor communication is often caused by high resistance in the ground wiring or loose connections. Ensure all wiring is secure and resistance is low.
● How to handle interference from electric motors?
Motor interference typically indicates that the cables require better shielding. Ensure you are using high-quality shielded cables.
● Does the system require a radio frequency permit?
No, the system uses protection loop lines for transmission and does not produce electromagnetic wave pollution, so no radio frequency application is required.
● Can this system operate in outdoor environments?
Yes, the system is enclosed in a heavy-duty composite Nylon Plastic housing and is designed to operate in extreme weather conditions.
● What is the maximum range of the intercom?
The effective communication range is more than 300 meters, provided the conductor loop resistance remains below 600 ohms.
