The Backup Power System uses a battery control board that monitors the charge condition of the
battery bank. This control board will command each of the gate operators connected to the system to
open sequentially thirty (30) seconds apart when the batteries reach a critical level and can no longer
maintain system operation. This assures that the vehicular gates will not remain in a closed position if
the battery power is depleted.
5.1.1 NORMAL OPERATION
The 2352 circuit board monitors AC power during normal operation and DC battery voltage during
inverter operation. When AC power fails, the system automatically switches from charger mode to
inverter mode. As the inverter draws DC power to operate the access control system, the 2352
monitors the DC battery voltage. When the battery voltage reaches a critical level and access system
operation can no longer be maintained, the 2352 board will begin to command each of the gate
operators powered by the system to open sequentially in 30-second intervals, and will hold the gate
operators in the open position.
5.1.2 QUICK OPEN OPERATION
The 2352 board can be set to immediately open the gate operators upon AC power loss if this type of
operation is desired. Simply set programming switch 1 to the ON position. (Note: Programming
switches 2-3-4 are not used and should be left in the OFF position).
When AC power is restored, the 2352 control board will release each of the hold open relays one at a
time, and will then re-activate each relay for one (1) second. This resets the gate operator control
board so that the operators will return to normal operation.
