Beeper
The beeper on an ICT reader can be controlled internally by the reader itself or externally by grounding the
beeper wire.
Beep generated internally. Data sent to expander for processing.
The first beep that is emitted when a card is read is generated internally by the reader to acknowledge that the
card has been read.
The second beep (or beeps) are generated by the access control system to advise whether access has been
granted or denied.
Beeps generated by Reader Expander supplying 12VDC to the beeper wire.
This is achieved by the reader expander grounding the beeper via the BZ output.
