5.4.3.7.Power Failure
It is an input to the digital video recorder typically used for wiring the output signal pin from an
uninterruptible power supply (UPS).
Physical Configuration for Power Failure Input
The power failure input and ground of TeleEye GN8 digital video recorder have to connect to a
universal power supply circuit UPS in order to detect any power failure.
The UPS circuit setup above is used as an example. Not all UPS have signal output. Some UPS
have self-testing occasionally. Their signal output may toggled during tests.
UPS provides backup
power and sends a
power failure signal
to GN8 when the
main power does
not work ordinarily.
