PEPU2 – External Page Interface Unit
System:
DK40i Expansion KSU, DK424, DK424i
Circuits per PCB:
see interfaces)
Interfaces with:
built-in paging amplifier or page speaker
door lock control
external amplifier control
external paging 600 ohm (duplex) interface (one zone)
MOH control
night relay control
Older Version(s):
none
The PEPU is similar to the PIOU2 and PIOUS2, but supports fewer peripherals than both PCBs.
PEPU controls, indicators, and interface connectors are illustrated in
Table 9-4.
PEPU does not support the following PIOU2 and PIOUS2 options:
o Alarm sensor
o Four-zone page
o SMDR port
o Remote maintenance modem or ASCII terminal connector
o IMDU connection
Refer to Chapter 10 – Universal Slot PCB Wiring
Note
for installation of external options.

PEPU2 Installation

1. Make sure P15 is in the Mu Law position for U.S. and Canada.
2. Ensure the PEPU2 has been configured for the appropriate hardware options. (Refer to
Chapter 12 – Peripheral
3. Insert the PEPU2 (component side facing right) into the last slot (S16) of the Base KSU/
cabinet if the system has only a Base KSU/cabinet and no Expansion KSUs/cabinets. If there
are Expansion KSU/cabinets, install the PEPU2 in the highest slot number of the highest
numbered KSU/cabinet. Apply firm, even pressure to ensure proper mating of connectors.
4. After installing the PEPU2, gently pull the PCB outward. If the connectors are properly mated,
a slight resistance is felt.

PEPU2 Programming

Program 03: Specify Code 41 for the slot that will support a PEPU.
Program 10-2: Activates External Page with All Call Page (with access code
$OO &DOO 3DJH
button).
Program 77-1: Assigns relay control options.
Program 78: Sets Night Ringing over External Page.
