433MHz Remote Control for Electronic Door Lock LED Dry Contact Switch Module Wireless Access Control DC 5-24V 10A Relay Breaker

What's Dry Contact Module?The dry contact module is a versatile electrical switch that responds to external signals, controlling other electrical equipment. With no need to worry about directions or polarity during installation, simply ensure the correct signal current and voltage levels are maintained.Tips:1. The input voltage is DC5-24V. The load works both low-voltage and high-voltage according to your different needs.If the load works with high-voltage AC, the power supply of the load is also AC, and neutral wire is required (Wiring method 2).If the load works with the same voltage as the dry contact switch, they can share the same power supply (Wiring method 1). If the load works with a different voltage from the dry contact switch, please use another supply (Wiring method 2).2. If you control electrical locks by this RF switch and remote control, please choose the correct wiring method according to the working principle of the lock (Wiring method 3-6).3.If the remote control voltage is low, please replace the batteries immediately. (Low voltage in the remote control generally reduces the remote control range.)When using wireless electronic products, avoid metal covers, electronic devices, and strong electromagnetic fields. This can reduce the remote control's range or cause the malfunction.Operation method:

1. Clear code Press and hold the learning button on the receiver for 10 seconds. After clearing, the previously paired remote control will no longer be controlled.
2. Learn to match codes (pair with the remote control) (1) Jog learning method: Press the learning button on the receiver once, and the LED indicator light flashes once. Press the key on the remote once, the controller indicator light flashes, indicating successful code pairing. (2) Self-locking learning method: Press the learning button on the receiver twice, and the LED indicator light flashes twice. Press the key on the remote once, the controller indicator light flashes, the controller indicator light flashes, indicating successful code pairing. (3) Interlock learning method: Press the learning button on the receiver twice, and the LED indicator light flashes twice. Press the "ON" button on the remote once, the controller indicator light flashes, and then press the "OFF" button B on the remote control, the controller indicator light flashes again, indicating successful code pairing. (4) Time-delay off-mode learning method: Delay 5/10/15/20 seconds to close: Press the learning button on the receiver 4/5/6/7 times, the LED indicator light flashes once and then stays on, indicating that it has entered the learning mode. Press the key on the remote once, and the LED indicator on the receiver will flash three times and then turn off, indicating successful code pairing.
