This makes the system far more secure than fixed-code alternatives — ideal for gates, industrial machinery, and sensitive installations.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How many remote controls can I pair with this wireless relay kit?\u003c\/h4\u003e\n\u003cp\u003eA: The receiver can store up to 30 individually coded remote controllers in memory, all operating the same 12 channels.
