Emergency Retract works for approximately 30 minutes depending on the size of the curtain.
* Emergency Retract buttons are not supplied as standard. Please ensure you check with the appropriate authority if emergency retract is required.
Message 1 – Curtain descending
Message 2 – Curtain obstruction
Red Light – Flashing (not strobe) to indicate that the unit is operating.
A pressure sensitive strip on the bottom bar senses the obstruction, causing the curtain to retract, pause, play the obstruction message, then descend again. This sequence is repeated three times in a row before finally descending regardless of obstruction.
The Light Curtain detects any obstruction within the whole opening. The Beam is a single horizontal beam, fitted at low level.
After 10 seconds of either being obstructed, the Voice Warning or Audio / Visual Beacon activates. This is a warning device only. The curtain will descend in the event of activation.
The system is activated from main system or heat, smoke or thermal fuse alarm inputs. Detectors can be wired in series to extend cover.
