Indicators
Two LED’s are located on the front of the SPS325.
The ON LED indicates the presence of 24vdc power.
The SIGNAL LED indicates the presence of audio.
Installation
Power and signal are connected through an RJ14
modular jack on the back of the SPS325. A modular
cord, power cord, jack block, and power supply are
included with the SPS325. Refer to the wiring illus-
