Capable of switching 15 amps of 120-volt AC power

The FSR SPC-15X is the expansion unit to the SPC-15 that provides sequential switching of one load (amplifiers, etc.). It is controlled by the SPC-15. An unlimited number of SPC-15X’s can be used in an installation. Each SPC-15X can switch 15 amps of 120-volt AC power.

The SPC-15X expansion unit has a 3-year warranty included.

Initiating power-up sequence

To initiate a power-up sequence, push the system power button. The system LED will start to blink to confirm system turn on and indicate that circuit 1 has been activated. The time between each circuit power-up is set by the initial delay adjust. When the final circuit is powered, the system LED will stay on and the power-up is complete.

Initiating power-down sequence

To initiate a power-down sequence, push the system power switch again. The system LED will start to blink to confirm a power-down. At this time, the external circuits will begin to power down starting with the furthest stage. All delays are the same as the power-up. A trip input from the fire alarm or other emergency signal will override all other inputs and cause the system to sequence down. The trip LED will illuminate in response to a trip. In order to extinguish the trip lamp, the trip input must be cleared, and then the momentary system power switch must be pressed.
