Interface Your Paging System with
Nearly Any Phone System!
Features
Viking’s Telecom Paging Interface allows you to
provide paging from nearly any phone system
instead of from a microphone. You can also
provide background music and electronic night bell
over the audio system.
The
PI-1A
features a built-in voice activated (VOX)
relay which provides DPDT contacts for muting
background music during paging. The relay is also
activated by AC ring for providing electronic night
bell. These contacts are necessary when
interfacing with systems such as Panasonic, South
Western Bell, Intertel, etc., which do not provide a
paging contact closure.
In the event a paging port is not available, the
PI-1A
can provide talk battery to allow connection
of the public address system to an unused
line/trunk input on the phone system.
The electronic night bell feature is activated by a
standard ringing analog PABX/KSU station circuit
or by a common audible contact closure provided
by an electronic key system. The ring pitch and
volume are adjustable allowing you to differentiate
between multiple ringing lines.
