Introduction  
The Call Stacker is a microprocessor based audio  
recording and announcement system. The Call Stacker is used in conjunction  
with a paging system to provide buffered announcement play to the paging  
system.  
Figure 1-1. Call Stacker Unit  
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 eliminating  
frustrating delays encountered when accessing the paging system. The recorded  
announcements are queued in order so the first announcement recorded that has  
hung up, 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 paging system.  
Once the complete recorded announcement plays to the paging 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 entered prior to recording  
an announcement which, upon output, precede the recorded announcement and  
select the paging system's paging zone.  
NOTE: Associated  
equipment would need  
to be powered by an  
uninterrupted power  
supply.  
The Call Stacker is equipped with battery backup which allows it to operate for up to  
two hours, from a fully charged battery, if a power failure occurs.

2. Set the option switch on the Call Stacker (see Figure 3-1 on page 3-2) for the  
desired system configuration (refer to Table 2-1).  
NOTE: When the 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 the switch

3. Connect the Call Stacker to the paging system (see Figure 2-4):  
Connect the Call Stacker's Page Output to the attendant override (attendant  
access control leads) or incoming alarm signal from the paging system.  
NOTE: PBX and KTS  
stations must have the  
ability to send a  
forward disconnect to  
the Call Stacker's  
Station inputs.  
Connect one or more of the Call Stacker's Input Station channels to PBX/KTS  
analog station inputs on the telephone system through FCC/DOC approved  
modular jacks.Connect the Call Stacker's Page Output channel to the paging  
system as shown in Figures 2-4 and 2-5 through an FCC/DOC approved modular  
jack. The control contact signal is used to secure and release the paging system  
controller (see figure 2-3).
