Gate Status Indication (optional feature)
The controller can provide visual indication inside the house of the position of the gate and the condition of the
battery and power supply. A LED is typically mounted on the intercom inside the house. The different signals of
the LED are described below:
Battery Low Protection
The controller has circuitry that monitors the state of the battery. During a power failure energy is drawn from the battery, but
not replaced. To protect the battery from being quickly damaged, the protection circuitry prevents the motors from being run
off the battery when the battery voltage drops below 10.6 volts.

Status LED location on the CP75 Controller Card
Indication that the battery low protection has been triggered is provided by the small gate status LED mounted on the
intercom inside the house, which will flash three times every two seconds . The gate system is shut off for at least one minute.
After this time the gate system can be reactivated but will shut off immediately again if a battery low condition persists.
CONTACT YOUR LOCAL GATE AUTOMATION SPECIALIST OR CENTURION SYSTEMS IF YOU DISCOVER
THAT THE BATT LOW SIGNAL GIVEN BY THE LED INSIDE THE HOUSE CONTINUES TO RE-OCCUR.
