EXTERNAL SPEAKER UNIT (HESB)
OPTIONS
4.00 STRATA DK8 and DK16 systems provide
three options utilizing an HESB:
4.01 DK8 and DK16 Loud Ringing Bell Option.
The Loud Ringing Bell option allows the voice first
or ringing signal tone to be amplified without the use
of other manufacturers’ equipment. The voice first
and ringing signal tones can be amplified on all
6500-series electronic telephones and 2000- and
1 OOO-series digital telephones equipped with HHEU
PCBs (refer to Section 100-816-206). The HESB
automatically turns off once the ringing call or voice
first has been manually answered from the elec-
tronic or digital telephone. This turn-off feature
prevents audio feedback problems.
4.02 Amplified Speaker Option. The Amplified
Speaker option allows the HESB to be configured
as a paging speaker. The HESB is connected to the
600 ohm Page RCA jack on the DK8 KSU or DK16
Base Unit to provide an amplified external speaker.
4.03 Talkback Amplified Speaker Option. The
Talkback Amplified Speaker option allows a talkback
speaker to be provided in areas where a telephone
is not needed. In this configuration, the HESB is
connected to the 600 ohm Page RCA jack on the
DK8 KSU or DK16 Base Unit and is used as the
amplifier and speaker. The door phone unit (MDFB)
is connected to the HESB, and serves as a micro-
phone to provide talkback operation. (The MDFB
microphone is always on in this application so the
pushbutton is inoperative, and the unit serves only as
a microphone for talkback.)
NOTE:
The 600 ohm Page RCA jack is two-way
(duplex) and is compatible with most commer-
cially available talkback amplifiers.
4.10 System Hardware Requirements
4.11 System hardware requirements vary de-
pending on the HESB option selected. Refer to the
following installation procedures for the system
hardware requirements for each option.
