The Firecom UH-51S wired headset delivers all the benefits of hands-free, full-duplex communication with your crew. Operating with a stand-alone intercom system or integrated with a mobile radio, the flexible design brings all crew members into constant communication. Behind-the-head band configuration with adjustable over-head strap easily accommodates use with helmets. Waterresistant and comfortable ear seal, extended operating temperature, and robust design make this headset ready for action in virtually any fireground environment. The single slotted dome does not provide hearing protection.
