Frequently Asked Questions
Q: What devices can I control with this DC 12V wireless relay switch?
A: This relay switch is compatible with a wide range of DC 12V-powered devices including garage doors, LED lighting systems, motorized curtains, door locks, and other access control or automation equipment. It's ideal for both DIY home automation and professional installation projects.
Q: How many remote controls can be paired with this receiver?
A: The receiver supports up to 16 different encoded remote controls. You can pair multiple remotes and assign them to the same channel, giving multiple users easy access to the same controlled device.
Q: What is the difference between the four working modes?
A: Jump switch toggles the relay on/off with each button press. Point action activates the relay only while the button is held. Self-locking keeps the relay latched on after one press and off after a second press. Interlocking is used with multi-channel setups to ensure only one channel is active at a time. All modes are user-selectable to suit your specific application.
Q: What is the maximum wireless range of the remote control?
A: Under typical open-air conditions, the remote control operates effectively at distances of 20–40 meters (approximately 65–131 feet). Walls, metal enclosures, and other obstructions may reduce this range.
