Phone-Com Systems

The Phone-Com intercom system provides direct, wired, point-to-point communication. Voice contact to any phone in the system is as easy as lifting the receiver and pressing the call button. Phone-Com operates on 12 VDC. They are constructed of high-impact plastic and are available in either classic white or traditional black. Wall mounting bracket is provided. Two versions are available:

PI-2: Designed for communication between only two points. A single call button sounds a buzzer and illuminates an indicator lamp on the companion phone. Available singly or as a set with 40′ of interconnect wire, fuse, terminal lugs and mounting hardware.

PI-10: For multiple station calling capability. Up to 10 phones may be interconnected, and each phone has 10 call buttons. Sold individually–see wiring requirements in the next column.
