Trouble/Time Limited Warning of Stand-by Batteries:
For compliance with ULC S318-96, 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 UL Listed Burglar Alarm
or Access Control Panel. The following figure shows the circuitry needed for local annunciation.
