GDC-3 is a wireless Garage Door Control designed to remotely operate garage doors and provide real-time status monitoring. It enables users to open or close the garage door while enhancing operational safety and security. By integrating with a Garage Door Tilt Sensor (GDTS-S) installed on the surface of the garage door, GDC-3 is capable of detecting door position, including fully open, closed, or partially open states. Upon garage door movement, the device provides visual indication and emits audible alert beeps through its built-in siren to warn users nearby and help prevent accidental incidents during operation.

GDC-3 transmits wireless signals to the Control Panel for remote monitoring and system integration, allowing users to manage garage access conveniently. It is suitable for residential and light commercial applications, providing reliable wireless control as part of a security system.
