INTROdUCTION
The FM-1/FM-1R was developed to address the growing need for cabinet and rack system cooling,
and it does so in a quiet, low profile and unobstrusive fashion.
This single-rack fan design will draw up to 150 cubic feet of air per minute. Dual 12VDC brushless
motors maintain whisper quiet operation without noise feeding back into the 120V circuits.
Temperature-sensitive speed control provides just the right amount of cooling at just the right
times, thus minimizing background fan noise. The remote trigger input turns the fan on and off
when needed. The trigger loop output can be daisy chained to additional triggerable devices or
FM-1s, and the two-minute turn off delay circuit prevents heat build up in the rack once the
equipment has been turned off.
