BSX Isolated Audio Entry System
PD-142 Issue 1 Installation and Operating Manual Page 9 of 32
Exit (Egress) Button
An exit button is used to unlock the door for the pre-set lock operating time. The input on
the controller is designed only for use with a normally open push button.
DDA Panels
The BSX system can meet the requirements of the Disability Discrimination Act (DDA).
Several options are available if required.
In the flat the availability of extension sounder and strobe accessories is the main
provision. Connection to other more specialist third party devices is also possible because
the ring signal is presented as an intermittent 12V output. Bell System will provide
technical information as required to those third parties, though this manual should be
sufficient.
At the door panel reassurance tones are standard, however DDA panels with visual
indication of Ringing, Speaking and Lock release via three LED’s are available on request.
Either high visibility halo buttons or illuminated tactile buttons are available for the call
buttons. The tactile buttons have raised illuminated numerals for the flat number; however
there is a limited range of numbers available. (Contact sales for further information).
Cable Requirements
Use 0.5mm solid-core twisted-pair phone cable (BT specification CW1308, Cat5 or
equivalent) for all phone and door panel connections; this is essential for correct operation
of the system and for compliance with European EMC Directive 89/336/EEC. Avoid
running any cables alongside mains or other data transmission wiring.
