SECTION 7 EXTERNAL RECORDING SYSTEM / EXTERNAL RINGER
7.1 External Recording System or External Ringer
The IP1WW-2PGDAD allows the connection of an external recording system or
external ringer. With a customer-provided tape recorder, when an extension user
dials the ACI analog port extension number, they can automatically start the
recorder and activate the record function. When the user hangs up, the recording
stops and the tape recorder turn off. For tape recording, connect the tape recorder
AUX input jack to the IP1WW-2PGDAD jack. Connect the recorder control leads (if
available) to the CTL (control relay) jack. By using Department Calling, you can
arrange multiple tape recorders into a pool. When an extension user dials the
Department Group pilot number, they reach the first available tape recorder in the
pool.
The relays in the IP1WW-2PGDAD can optionally control customer-provided
external ringers (loud bells) and buzzers. When an extension user dials the ACI
analog port extension number, the associated IP1WW-2PGDAD relay closes and
activates the ringer. You could use this ability to control an emergency buzzer for a
noisy machine shop floor, for example. In addition, if programmed for ringing, an
incoming trunk call can activate the ringer/buzzer.
