USER GUIDE
Operating description
The WDD is a wireless sensing edge system. The sensing edge is conformed of, a conductive rubber section, sealed
wireless transmitter, and end cap. The sensing edge is installed the full width of the door in the doors soft bottom bag.
wireless transmitter, and end cap. The sensing edge is installed the full width of the door in the doors soft bottom bag.
Obstacles/obstructions in the door opening will be sensed by the edge when the door comes down and makes contact
with it. The conductive rubber triggers the transmitter to send a signal to the controller to reopen the door. A very short
and rapid transmission happens only when the sensing edge makes contact with an obstacle/obstruction and will not
trigger again until that sensing edge returns back to the open state.

The system operates according to the open loop principle. The open loop operation offers a longer life for the
transmitters lithium battery, because energy is consumed only when the sensing edge makes contact with a obstacle/
obstruction, otherwise it is inactive.

Technical description of the Sensing egde
Material:
EPDM 65 degrees shore A
Operating temperature:
-20°C to + 80°C
Protection index:
IP 67 with two sealed ends
Operating Mode:
The rubber section consists of two conductive rubber sections that each envelop a copper
wire, and an outer insulating section of non conductive rubber. Pressure lower than 10N on the
bottom of the section creates a short-circuit between the internal conductive parts and transmits
a closed contact to the extremities through the copper wires.
