Product Details

The ZPI-4 is a four-zone touch tone controlled paging system capable of switching a line level signal (600 Ohms) to amplifiers, an amplified signal to 70V speakers, or an amplified signal (200 Watts maximum) to 8 Ohm speakers.

The ZPI-4 features balanced audio circuitry throughout for low noise and compatibility with balanced paging system inputs and outputs. There are separate level controls for paging and background music, and background music can be disabled on a per-zone basis. Also provided is a night bell with adjustable volume activated by a dry contact closure or a ringing analog PABX/KSU station.

The ZPI-4 is compatible with ringing analog PABX/KSU station ports (disconnects on silence, CPC, busy, touch tone (#) or timeout) as well as unused trunk inputs, and will interface directly with standard paging ports.

Applications

Multiple zone paging for phone systems with paging ports, unused analog station ports or unused trunk inputs
Multiple department manufacturing business
