The Simplest and most workable way to attach an access
control system with a Door is using a Limit Switch, which will make an
Air Curtain operational as soon as the Door opens.
Various kind of options is available for various Doors as
stated in the PIC attached. Best Suited is the Magnetic proximity Switches,
they work on magnetic inductions. The effective range is within 10 mm. It
consists of 2 Magnets one gets installed on the Door (which moves along with
the Door) and one on the frame (Fixed One).
The Air Curtain already has a Loop with the Lead, you attach
the Limit Switch wires along with it as per the Drawing, and the Terminals are
attached to the Switch. So that whenever the Magnets are away from the Air
Curtain starts (as shown in PIC 3)
