Connecting a Nurse Call System or Remote
Alarm
The remote alarm port is behind a protective rubber ap on
the back of V*Home. This port may be used to connect a
remote alarm, a nurse call system, or other alarm systems that
sense contact closure through a 1/4” phono jack. Only use
the remote alarm port with Ventec Nurse Call cables or other
cables approved by Ventec Life Systems. Follow all setup
instructions provided by the remote alarm or nurse call system
manufacturer.
If used with a remote alarm, position the remote alarm so that it
can be heard by the clinician or caregiver at all times.
Always test the alarm immediately after installation, and
periodically during use to ensure it is functioning as intended.
NOTE: Normally open nurse call systems may not cause an
alarm condition when disconnected from V*Home. Follow all
instructions provided with the nurse call system to ensure safe
operation.
WARNING: To reduce the risk of electrical shock, ensure the Nurse Call System connected to V*Home meets the Safety
Extra Low Voltage (SELV) requirements as described in IEC 60601-1 (1988).
Safety Extra-Low Voltage (SELV): Voltage which does not exceed nominal values of 25 VAC or 60 V DC at rated
supply voltage on transformer or convert, between conductors in the earth-free circuit which is isolated from the supply
mains by a safety extra low voltage transformer, or by a device with equivalent separation.
Safety Extra-Low Voltage Transformer: Transformer with an output-winding which is electrically separated from earth
and the body of the transformer by at least basic insulation and which is electrically separated from the input winding
by an insulation at least equivalent to double insulation or reinforced insulation and which is designed to supply Safety
Extra-Low Voltage circuits.
WARNING: To reduce the risk of electrical shock in the event of a failure of Nurse Call System’s electrical separation
from supply mains, operator should not simultaneously touch the patient and any exposed metal on the V*Home rear
housing, including: the DC power connector shell, either high or low pressure oxygen connectors, and/or the exposed
metal screw above the Nurse Call/USB port.
