CHEMICAL AGENT DETECTION AND ALARM SYSTEM - Continued
When used with the M992, the following instructions also apply.
When vehicle is parked, connect detector unit (1) to vehicle hook-ups (2) via
telephone cable (3). Detector must then be operated by its own power supply (4).
Detector may also be used inside cargo compartment during transit, although ef-
fectiveness may be greatly reduced. For unit to operate in this situation, vehicle
MASTER switch must be ON; detector and alarm system will then operate using
vehicle electrical power.
During periods of continuous operation, detector units
fluid reservoir and air filter must be changed every 12
hours. When operating less than 12 hours per day, reser-
voir and filter must be changed daily. See TM 3-6665-225-12
for complete instructions. Failure to observe this warning
will greatly reduce the effectiveness of the system.
