EnOcean wireless wall transmitter 1-channel in matte black (painted) for System 55. This wireless transmitter sends switch, dimming, or blind commands to EnOcean radio system receivers. It is a battery-free device that does not require an external power supply. The transmission energy is generated from mechanical energy when the switch is pressed. Both encrypted and unencrypted radio transmissions are possible. Installation can be done on a device box or on smooth, flat surfaces using screws or adhesive. This product is not suitable for eNet. Gira EnOcean transmitters are compatible with third-party actuators. The package includes the wireless wall transmitter, a mounting plate, adhesive film (privacy protection for glass surfaces), and adhesive dots for installation on smooth, flat surfaces.
