Trouble/Time Limited Warning of Stand-by Batteries:
The 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.
