🛡️ Product Description
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.
Safety First
Mainly used on construction and temporary Hoists/Elevators, this system is 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 and adding to project profit.

❓ FAQ
Q1: What are the main benefits of using this intercom system?
A: It provides crystal clear communication for safer work environments, increases productivity by allowing staff to locate each other quickly, and reduces liability risks in emergencies.
Q2: Does the system require a radio frequency license?
A: No, the system does not produce electromagnetic wave pollution and does not require a radio frequency application, making it ideal for intensive construction areas.
Q3: What should I do if the communication fails?
A: Check if the protective ground wire is improperly grounded in the middle, or ensure the protective earth wire and ground wire in the hanging basket are correctly connected.
Q4: Can this system withstand harsh outdoor environments?
A: Yes, it is designed with a heavy-duty composite Nylon Plastic enclosure and is built to operate in extreme weather conditions.
Q5: What is the maximum effective range of the intercom?
A: The system supports an effective range of more than 300 meters, provided the conductor loop resistance is less than 600 ohms.
Q6: What causes poor communication or interference?
A: Poor communication is often caused by high resistance due to bad wiring connections. Interference from electric motors usually suggests that the cables require better shielding.
