Strata CTX I&M September 2002
External Speaker Unit (HESB) Options
Strata CTX systems provide three options utilising 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 digital
telephones equipped with HHEU PCBs and HESB. (See
.)
The HESB automatically turns Off once the ringing call or voice first has been manually answered
from the digital telephone. This turn-off feature prevents audio feedback problems.
Important!
For UK & European markets a 240VAC to 12VDC plug to power supply must be
provided by the dealer.
