BLE’s electronic control systems are designed in-house to ensure compatibility with the mechanical aspects of the product. All our curtains operate on a gravity fail safe basis to ensure the highest level of safety even if the mains power supply has been compromised. Back-up batteries are supplied as standard to allow the system to operate as normal for up to 4 hours in the event of a temporary power outage.
BLE Group Control Panels (GCP) can control up-to 6 curtain motors, regulating the deployment and retraction of the curtains. In normal conditions the GCP provides a 24V power supply to the motors and the curtains are held in the retracted position in the head box.
