Intrinsically Safe Remote Speaker Microphone

High-output 2.0W intrinsically safe speaker mic for hazardous workplaces.

The Icom HM169 IS (also designated as HM-169 IS) is a genuine OEM intrinsically safe remote speaker microphone engineered specifically for volatile, hazardous work environments. Designed for use in chemical plants, fuel refineries, and combustible dust facilities, the Icom HM169 IS prevents internal electrical or thermal sparks that could ignite surrounding atmospheric gases or vapors.

Delivering a commanding 2.0 watts of typical audio power output from a large-diameter internal speaker element, the Icom HM169 IS ensures clear, intelligible voice reception over sirens and heavy machinery noise. A heavy-duty 9-pin spring-type connector clamps securely into the host radio chassis, eliminating intermittent signal dropouts during active movement. For complete hands-free operation, the Icom HM169 IS features a 360-degree high-tensile rotary clip that anchors firmly to work gear or turn-out coats.
