Failsafe; If a fault occurs i.e. losing mains power, damage to the Panachrome+ Controller, extension cables or detectors, the doors will remain open in a safe position without trapping passenger.
The Panachrome+ Controller will require the correct signal from the door operator either Normally Open (N/O) or Normally Closed (N/C) contacts to allow lift doors to return to an open state.
To check failsafe; disconnect working detectors from the Panachrome+ Controller, the doors will remain open, if doors close then the Panachrome+ is not failsafe.
