OPERATION
The Call Stacker features 5 Input Station (recording) channels, a single Page Output channel and
3 minutes of recording time.
Up to 5 announcements can be recorded simultaneously, virtually elimi nating frustrating delays
encountered when accessing the paging system. The recorded announcements are queued in order so
the first complete announcement recorded, plays first, followed by the second announcement, etc.
The Call Stacker allows users to verify their announcements before they play to the paging system. If a
user is not content with their recorded announcement, they can re-record it repeatedly until they are
satisfied.
The Call Stacker's Page Output channel interfaces to the paging system's control unit. Once an
announcement is recorded, the Call Stacker plays the announcement over the Page Output channel to
the paging system. While the recorded announcement is playing, the Page Output channel provides a
contact closure to the pagi ng system.
Once the complete recorded announcement plays to the pagi ng system, it is erased from the Call
Stacker, freeing up the recording time for new announcements.
The Call Stacker can be configured to record and play back paging zone selection signals. Between 2
and 4 DTMF digits can be ent ered prior to recording an announcement which, upon output, precede the
recorded announcement and select the paging system's paging zone.

NOTE: When switch #7 is “OFF”, there will be no delay in time from when the paging system zone is
accessed until the time when the message is sent. When switch #7 is “ON”, ther e will be a 2 second
delay from when the paging system/zone is accessed until the time when the message is sent. The
delay is installed in order for a Confirmation/Pre-announcement tone (if available or optioned) to be
played over the system before the message is sent.

on the telephone system through FCC/DOC approved modular jacks. Connect the Cal l Stacker's
Page Output channel to the paging system as shown in Figures 4 and 5 through an FCC/DOC
