【Electronic Lock with Lever】There are two parts: the black-painted "fixed" part and the metal hook. You have to slam the door to close it and apply 12V to the wires to unlock it. The electromagnetic lock is mainly made of carbon steel; the locking hook can withstand a pull of 150kg. Electromagnetic lock 【Open via Intercom】The lock can be opened via intercom with a little DIY. You just need to send a 12V 2A pulse, so you'll need a small relay in case of insufficient power, along with a 12V 3A power supply. To secure the cupboards, so that children cannot access them. 【Precautions when Connecting】Electromagnet. The lock should not be powered for more than 3 seconds and the voltage should be 12V 2A. If you are using a relay with a keypad, everything will turn off when you unlock it. Because the power supply is not powerful enough, you must power the lock separately or use a dedicated power supply for the lock. 【Energy Saving and Long Lifespan】Shockproof, puncture-proof, and anti-theft protection.
