Rescom Modular is a high-performance, hard-lined system that meets all Occupational Safety and Health Administration confined space entry standards. This intrinsically safe, hard-lined system was designed to provide clear, reliable communications, as you are directly connected to those you are communicating with. Full duplex transmission allows clear, effective and continuous communication, ensuring no messages are missed. Rescom headsets can be worn under helmets and come in a variety of styles. The system operates on two AA batteries and can support between two and ten workers up to 300 hours. Setting us apart from other hard-lined systems on the market is our 10,000-pound test strength NFPA rated Rescom Communication Rope- rescue rope with communication wires built into its core. The durable polyester rope protects the communication cables from damage. For identification purposes during multiple entrants’ rescues, the rope is available in five colors, and lengths up to 1,500 feet. For more information, click here.
