Connecting the smoke sensor Smoke Sensor Operation NOTE: The smoke sensor is for use only with the CMC and is not suitable for connection to building fire alarm systems. Smoke passing by the sampling tube will be drawn into the optical smoke sensor by the fan. The smoke sensor can take up to 20 seconds to trigger an alarm to the CMC. The sampling tube must be placed in the path of the exhaust air from the rack equipment. If smoke is detected, the sensor fan will automatically shut off. After the smoke has cleared, the sensor can be reset by pressing the RESET button for three seconds. The sensor will not detect smoke if the fan stops running or runs too slowly. A fan fault like this will also trigger a smoke alarm. A smoke alarm should be investigated to determine whether smoke is present or a fan fault occurred.

Smoke Sensor Operation
NOTE:
The smoke sensor is for use only with the CMC and is not suitable for connection
to building fire alarm systems.
Smoke passing by the sampling tube will be drawn into the optical smoke
sensor by the fan. The smoke sensor can take up to 20 seconds to trigger an
alarm to the CMC. The sampling tube must be placed in the path of the
exhaust air from the rack equipment.
If smoke is detected, the sensor fan will automatically shut off. After the
smoke has cleared, the sensor can be reset by pressing the RESET button for
three seconds.
The sensor will not detect smoke if the fan stops running or runs too slowly. A
fan fault like this will also trigger a smoke alarm. A smoke alarm should be
investigated to determine whether smoke is present or a fan fault occurred.
