 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) or AC ring activated
relay which provides D.P.D.T. contacts for muting background music during
paging or to provide an 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. |
