5 EXTERNAL SPEAKER UNIT (HESB)
OPTIONS
5.00 STRATA DK systems provide three options
utilizing an HESB:
5.01 Loud Ringing Bell Option. The Loud Ring-
ing Bell option allows the voice first or ringing signal
tone to be amplified without the use of other manu-
facturers’ equipment. The voice first and signal
tone can be amplified on all electronic and digital
telephones equipped with HHEU PCBs. (Refer to
Section 400-096-207.) The HESB automatically
turns off once the ringing call or voice first has been
manually answered from the electronic or digital
telephone. This turn-off feature prevents audio
feedback problems.
5.02 Amplified Speaker Option. The Amplified
Speaker option allows the HESB to be configured
as a paging speaker. The HESB is connected to the
PIOU, PIOUS, or PEPU 600-ohm page output to
provide an amplified external speaker.
5.03 Talkback Amplified Speaker Option. The
Talkback Amplified Speaker option allows a
talkback speaker to be provided in areas where a
telephone is not needed, such as in conjunction
with a door phone. In this configuration, the HESB
is connected to the PIOU, PIOUS, or PEPU 600
Ω
(duplex) output and is used as the amplifier and
speaker. The door phone unit (MDFB) is con-
nected to the HESB, and serves as a microphone
to provide talkback operation (the MDFB push-
button is inoperative, and the unit serves only as a
microphone for talkback).
NOTE:
The PIOU, PIOUS, and PEPU 600
Ω
(duplex)
page output is compatible with most commer-
cially available talkback amplifiers.
5.10 System Hardware Requirements
5.11 System hardware requirements vary depend-
ing on the HESB option selected. Refer to the
