Installation guide

Three Output Types
The PagePac Plus Control Unit has three audio outputs, with the level
controlled by an automatic gain control (AGC) to ensure excellent voice
clarity. The first is the audio output signal to the PagePac Plus
Amplicenter, in a Constant-Voltage Distribution System (see "Hardware
Configuration," below.)
The second audio output is intended to drive (for example) an additional
PagePac Plus Control Unit. Only one external device may be connected
to this output if talk-back is required.
The third output is intended to drive up to 56 remote amplifiers, via Zone
Expansion Units.
See the Installation Guide for details of connections.
Talk-Back Amplifier
The talk-back amplifier has automatic gain control to ensure excellent
voice clarity from audio received from paging zone speakers.
Tone Generator
The PagePac Plus Controller has the ability to generate several distinctive
tones such as siren, chime, dial tone, beeps, and night bell. These tones
may be sent to either the paging amplifier or to the telephone interface,
depending on the situation. For a description of the tones, see "Tone
Selection" in section 2, under Telephone Keypad Programming.
Programming Memory
The PagePac Plus Control Unit has the ability to retain all programming
options in non-volatile (EEPROM) memory.
Hardware Configuration
The PagePac Plus system can be configured to operate in several
different ways, as a constant-voltage distribution system, a controller
system, or a hybrid system. In any of the configurations, a PagePac Plus
Amplicenter is required and the interconnection between the Control Unit
and the Amplicenter must be made.
