10 EXTERNAL PAGE INTERFACE UNIT
(PEPU)
10.00 General
10.01 The External Page Interface Unit (PEPU)
provides a circuit interface with the system periph-
eral options. The PEPU is similar to the PIOU, but
supports fewer peripherals. In general, PEPU-sup-
ported peripherals are related to paging and relay
control functions.
NOTE:
If a PIOU or PIOUS is installed, then a PEPU
cannot be installed.
10.02 PEPU controls, indicators, and interface
connectors are shown in Figure 6-l 3 and described
in Table 6-l.
10.10 PEPU Hardware Options
10.11 The PEPU supports the following hardware
options:
External Options
l
Built-in Paging Amplifier
l
Door Lock Control or External Amplifier Control
l
External Paging 6OOQ (duplex) Interface (one
zone)
l
Music-on-Hold Control or Night Relay Control
NOTE:
Refer to Peripheral Equipment Installation,
Section 200-096-208; and Wiring Diagrams,
Section 200-096-209, for installation of exter-
nal options.
