LED’s

There are two LED’s on the front panel of the FM-1/FM-1R.		Red “Power” LED
a) The red LED signals “power” (the unit is plugged	FM-1 SYSTEM COOLING MODULE

into a wall receptacle and receiving power from		Green “Fan	on” LED

the 120V outlet).

Out of the Box Operation

When the FM-1/FM-1R is plugged into a 120V power Home Theater Receiver outlet and no cable is plugged into the Trigger

Input jack, both LED’s will light and the fans will begin to move air.

Utilizing the REMOTE ON/OFF Feature

Figure 4

The FM-1/FM-1R contains a REMOTE ON/OFF feature that enables the fans to begin air movement only when your system’s audio equipment“tells” it to do so. The fans will begin blowing and the green LED will light when the FM-1/FM-1R receives a 12V trigger from another source. At the rear of the FM-1/FM-1R are the “Trigger” input and control output jacks. Both jacks accept an 1/8” male “mini” plug.

Dual Male ‘Mini’

plug cable

The FM-1/FM-1R “Trigger” input jack accepts 3 to

24V (DC or AC) from either another audio component that transmits this type of trigger voltage or a standard 12V (DC or AC) power transformer plugged into the switched outlet of an audio source (remember, the FM-1/FM-1R only accepts a 1/8” inch mini plug––no cannon plugs!) The “Control” output passes 11VDC, 20mA (max) power along to the next component.

See Figures 4 and 5 on this page and Figure 2 on the previous page for some applications where the FM-1/FM-1R is utilized to cool a source and/or power amplification component.

Temperature Sensing

The FM-1/FM-1R’s temperature-sensing variable speed fans detect the amount of heat being generated by the components in its proximity and adjust the fan speeds accordingly––slowing them down when the system is first turned on or if listening at low levels where the system’s amplifiers are not producing as much heat, or speeding them up in order to quickly dissipate more heat.
