Overview
The Model 262 is
designed to provide a voice paging connection between a telephone system
and one zone of a voice paging/background music system. The unit is
compatible with virtually every telephone system, inter-facing with a
PBX system via a loop start or ground start trunk port, or with a key
system via a central office lineposition.
The audio output
directly connects to most audio amplifiers and/or amplified speakers. A
normally open (not shorted) relay contact is provided for
installer-selected applications. The relay contact closes (shorts)
whenever a page is taking place. The relay is typically used to provide
the paging equipment with a “page enable” signal.
The Model 262 contains
a special circuit that eliminates the extraneous clicks and pops
commonly associated when accessing a paging system from a telephone
system. The Model 262 provides a quiet beginning to all pages. A “pop”
or “thump” may still be heard at the end of a page. This is a technical
limitation that is common to most page adapter products.
Installing the Model
262 is fast and simple, with only one configuration switch to set. Two
LED indicator lights are provided to display power and off-hook status.
