Notes:
• During a fire alarm, the Fire LED is ON and the NX-1750 ProxPad buzzer sounds. Badging any
valid card silences the buzzer. To clear the Fire LED indication, badge and hold the card in
front of the reader. After the fourth beep, the Fire LED is cleared.
• When the communication with the control panel fails, the Fire LED flashes. Typically this is
caused by a fault in the databus wiring, e.g. loose databus wire.
• When service is required (e.g. a system trouble condition exists), all four top LEDs flashes
ON/OFF once every 2.5 seconds.
