4EXTERNAL SPEAKER UNIT (HESB) OPTIONS

4.00STRATA DK8 and DK16 systems provide three options utilizing an HESB:

4.01DK8 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 1000-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.

4.02Amplified 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.

4.03Talkback 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 microphone 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.

4.10System Hardware Requirements
