RJ45 Connection
Low Voltage Input (Blue Wire for BZ-50, RJ-45 cable for BZ-50RC, Yellow Wire for BZ-50RC with FS-C2):
The low voltage input wire carries the +12-24VDC maintained input Control ON signal to the BZ-50. Applying 12-24VDC to this input
closes the BZ-50 load relay. Removing the voltage returns the relay to its normal state. This input is intended for sensor or control device
input.

Over Current Protection:

The BZ-50 contains built-in short circuit and thermal protection circuitry that shuts down the +24VDC output (red wire to sensors) to
prevent permanent damage to the power pack. Removing the excess load from the output restores the BZ-50 to proper operation. The
excess load can be connected to another power pack.

LED Indicator:

The LED indicates the following conditions on the BZ-50:
• LED OFF: no power to the BZ-50, or the +24VDC output is shorted.
• LED ON, blinks once every 5 seconds: the relay is closed (load ON).
• LED ON continuously: the relay is open (load OFF).
• LED blinking continuously: current output limit is exceeded (too many sensors are connected to the power pack); +24VDC output
shut down.
