The MCB has 3 green lights Power Brake, status and one Red fault light.
When the curtain is retracting after an alarm, test or initial power up the
following lighting sequence should take place.

until the bottom bar hits the head box.
The mcb will detect an increase in amperage and reduce the voltage to hold
the motor to prevent it from rolling back
2) The close timer counts down and the power transfers to the brake
illuminating the brake light which then turns off the power light.
3) The status light stops flashing and the system is now armed awaiting a fire
signal in its standby mode with just the brake light illuminated.
once the panel receives a fire signal the intelligent system will release the
brake and use the energy the motor produces whilst closing to apply the
brake at intervals to close the curtain in a controlled decent
The red fault light will illuminate if there is a direct fault or short to
the board.
