Digital System Driver
The Digital System Driver provides the Control signals for the ScanALERT Digital System. Only one driver is required for each individual system. It is housed in a plastic enclosure and is installed with the Power Supply in a location with easy access for servicing.
Operation of this equipment is fully automatic. The System Driver generates a repeating buzzer signal to sound the buzzers in the Display Panels whenever a call is active on the system.
The System Driver includes a feature whereby a Call Point can be programmed to act as a priority call.
When this function is activated the system automatically gives priority to the special call, and will ignore any other calls until the priority call is reset.
A cut-off switch is provided on the System Driver to switch off the repeating buzzer signal. The unit is fitted with status indicator LEDs that show system operation and assist in diagnosing any problems.
The indications include Power Supply, Data Signal, Response from Call Points and Priority activation.
