摘要:
A system, kit and/or device is provided for replacing mechanical actuators with touch-less actuators in a 2-wire automatic door system. The system, kit and/or device includes a sensor module connectable to power and the motor and control for the door, and one or more touch-less switches each configured for electrical connection with the sensor module via two wires. The sensor module is operable to sense change in current by the touch-less switches, caused by actuation thereof to send a signal to the door motor and control for opening the door. The module conditions the voltage to give +12 volts to each of two touch-less switches. Current in each touch-less switch is one current for idle or another current when activated. This difference in current is sensed at the sensor module through the two wires. When the extra current is sensed a control signal to open the door is sent to the door motor control.
摘要:
The invention relates to a flooring panel having opposed pairs of substantially parallel side edges, a tongue connector member, and a groove connector member. In one aspect, the tongue connector member extends along one side edge and the groove connector member extends along the opposed side edge. The tongue connector member and the groove connector member are configured to cooperatively couple with each other such that portions of the coupled flooring panels are positioned in abutting relationship.
