Trouble/Time Limited Warning of Stand-by Batteries:
Time Limited Warning circuit must be connected for local or remote annunciation with an Amber or Red LED to
indicate DC Trouble (low battery, loss of battery or when 95% of the stand-by battery has been depleted). Connect
the circuit to the Batt Fail relay contacts to an appropriate input of a Burglar Alarm or Access Control Panel. The
following figure shows the circuitry needed for local annunciation.
