Exit Button
The exit button input is for a normally open contact button. When pressed the Lock output
will activate and the tone will sound for the Lock Time as set on the switches, see BSX2
Controller Settings on Page 14. If the exit input is triggered for longer than the lock time
then the lock output will continue to operate until the input is removed. The tone will
however stop after the lock time.
‘Exit +’ is the input and ‘Exit –’ is internally connected to 0V.
The ‘Exit +’ input
can also be used to allow other equipment to release the door.
Examples are shown on Pages 29 and 30.
If the exit button has a normally closed contact, then this can be wired in series with the
release or maglock and break glass. This will allow the door to be opened manually, even
if the equipment has failed, without having to break the glass.
Tone Output
Tone output is provided direct to the speech unit. The 801 and BS-LX phones generate
their own ringing tone which is not adjustable.
Busy tone and Lock operation tone is generated in the controller and is adjustable using a
volume control on the controller PCB (Page 27).
