Nurse-CallPin 9 of the RS-232 serial interface connector provides an Alarm Out signal. Any time there is any alarm condition active in the monitor, and if the Nurse Call Signal option in the Setup Menu is On, pin 9 goes to plus RS-232 level voltage (> +5 VDC). The alarm delay shall be < 0.5 seconds.

If in the Setup Menu, the Nurse Call Signal option is Off, pin 9 is always at the minus RS-232 level voltage. In order to make use of the Alarm Out signal, pin 9 should be connected to a high-impedance circuit (>1000) and protected against transient voltages.
