External Speaker Unit (HESB) Options

Strata CTX systems provide three options utilizing an HESB:

•Telephone External Ringer

•Amplified Page Speaker

•Talkback Amplified Page Speaker with talkback

System hardware requirements vary depending on the HESB option selected. See the following installation procedures for the hardware requirements for each option.

Telephone External Ringer

The loud ringing bell option enables the voice first or ringing signal tone to be amplified without the use of other manufacturers’ equipment. The voice first and signal tone can be amplified on all electronic and digital telephones equipped with HHEU PCBs and HESB. (See Chapter 7 – Station Apparatus.)

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.
