9) Set the PIOU or PEPU SW4 switch to the SPO
position.
10) Connect the HACU-120's +12V lead to Termi-
nal 1 of the HESB TB2 terminal block, and
connect the 0V lead to Terminal 2.
11) Plug the provided power cord into the power
supply and to a 117VAC, 60Hz power source.
5.26 Talkback Amplified Speaker Test. Test the
Talkback Amplified Speaker installation in accor-
dance with the following steps:
1) Make an external page.
•
Page will be heard over the HESB.
2) Verify that someone speaking into the door
phone can be heard at the paging station.
(With this application, pressing the door phone
button is not required to talk back through the
door phone.)
5.27 HESB Wall Mounting. Some applications
may require that the HESB is mounted on a wall or
other vertical surface. Mount the HESB in accor-
dance with the following steps (Figure 8-16):
1) Find a suitable location on the mounting sur-
face for the HESB.
2) Screw a 1.25-inch panhead wood screw into
the mounting surface.
3) Hang the HESB from the screw.
6 EXTERNAL PAGE OPTIONS

6.00 System Hardware Requirements

6.01 STRATA DK systems offer a variety of exter-
nal page options. Additionally, a Background Music
(BGM) option is available with each external page
option. DK systems support:
•
Paging with BGM (same amplifier)
•
Zone Paging with BGM (separate amplifiers)
•
Zone Paging with BGM (multiple amplifiers)
NOTE:
The PIOU PCB only is equipped with Zone
INSTALLATION-PERIPHERALS
Paging.
6.02 Either a PIOU, PIOUS, or PEPU PCB is
required to support the external paging/BGM op-
tions. The PIOU will support any of the paging/BGM
options. The PEPU and PIOUS will support only the
paging with BGM (same amplifier) option.

6.10 External Page Option Installation

6.11 All paging connections are made via the
PIOU or PEPU amphenol connectors or the PIOUS
TB1 terminal to the Main Distribution Frame (MDF).
6.12 Page (single zone) with BGM (same ampli-
fier). In this configuration, paging and BGM are
amplified by a common customer-supplied paging
amplifier. When the external page access code is
dialed, the external page control relay is activated,
which applies a short (or open) to the amplifier mute
control to mute the music. Install this option in
accordance with the following steps: (Refer to
Figure 8-17.)
1) Connect Input 1 from the paging amplifier to
Pins 13 (SPR) and 38 (SPT) of the PIOU or
PEPU; or connect to SPT and SPR of the
PIOUS.
2) Connect the paging amplifier mute terminal to
Pins 7 and 32 of the PIOU or PEPU; or connect
to DET and DER of the PIOUS.
3) Connect the music source to the Input 2 of the
paging amplifier.
4) Connect the speaker to the paging amplifier
output.
5) Verify that the PIOU or PEPU P10 jumper plug
is in the MAKE position or that the PIOUS W1
jumper wire is in the MAKE position.
6.13 Zone Page with BGM (separate amplifi-
ers). This configuration provides multiple-zone
paging capability. The output of the paging ampli-
fier is routed back to the PIOU, where it is switched
to one of four sets of speakers by PIOU Relays K1
through K4. The relay selected is determined by
the access code dialed by the station user. Default
access codes are:
