The Watchman Multigas Monitor has only three buttons. Its backlit liquid crystal display (LCD) continuously provides readings from all sensors. When a preset alarm condition is detected by any sensor, an internal horn activates and two bright red warning lights flash. The combustible sensor uses MSA's Lockalarm T circuit. If the combustible gas level reaches 100% of the lower explosive limit (LEL), the alarm locks and cannot be reset until the user moves to fresh air, turns the unit off and back on again.

The Watchman Multigas Monitor meets intrinsic safety testing requirements for use in Class 1 Division 1, Groups A, B, C and D; Class II Division 1, Groups E, F, G; and Class III hazardous locations.
