CHEMICAL AGENT DETECTION AND ALARM SYSTEM
M43 CHEMICAL AGENT DETECTOR - senses the presence of very low concentrations of
chemical agents and breathable aerosols. Contaminants are sensed by the detector and
an electrical signal is sent to the chemical agent alarm. The detector unit maybe operated
using power from the vehicles electrical system; it also may be battery operated.
M42 CHEMICAL AGENT ALARM-signals to crew members that chemical agents have
been sensed by the M43 detector. The alarm may provide an audible and visual signal or a
visual signal only, depending on setting.
