For Control Of LED Lighting, Air Conditioners and Intruder Alarms
The LD2100 is a battery-free, wireless, stand-alone door switch, designed for the control of LED lighting, air-conditioning or alarm systems without any wiring between the switch and the controller. Powered entirely by kinetic energy, it generates its own power each time the button is pressed or released, transmitting a signal to a paired wireless receiver.
In joinery applications, the door switch is simply fixed to the inside of the carcass, transmitting a signal to the receiver to control LED lighting as cabinet doors are opened and closed. When used with the LD2120 LED lighting receiver, the system includes fade-in/fade-out adding a level of sophistication.
For air-conditioning control, the switch can be used with the LD2125 receiver, to turn units off automatically when an external door or window is opened. Depending on the selected receiver, this can occur immediately or after a 60-second delay.
In alarm or monitoring systems, the LD2100 door switch can be attached to any door or window and paired with the LD2125 receiver for a wireless connection.
The LD2100 door switch supports one-to-one, one-to-many, and up to ten-to-one configurations, allowing multiple transmitters and receivers within a single setup. The unit has a lifespan in excess of 100,000 operations and provides a set-and-forget solution with reliable wireless performance.
