The working principle of the electric bolt lock determines the installation of the electric bolt lock, during the development of the access control system, the electric lock becomes the executive device, in order to be suitable for doors in more occasions, such as electric control locks, electric bolt locks, and magnetic locks have appeared, access control device such as, cathode locks, etc., have attracted the attention of users, among them, electric bolt locks are even known as the perfect match for glass doors. Let’s get to know it today.

What is the working principle of electric bolt lock?

The principle of the four-wire electric bolt lock: It consists of two wires, two wires, usually red and black, the red can be connected to the power supply +12VDC, and the black is connected to GND. There are also two white wires, which are the door sensor signal wires. The electric bolt lock also feeds back the signal to the access controller according to the current door switch state. For example, the unclosed state of the glass door for a long time is based on these signals to convey information. The four-wire electric bolt lock is controlled by a single-chip microcomputer, which can ensure a good heating state, and the products with delay control and signal feedback are widely used.

The principle of the five-wire electric bolt lock: The principle is the same as that of the four-wire electric bolt lock, except that a pair of opposite signals of the door sensor is added, it is used in some special occasions for price comparison, because there are more wire groups, it is necessary for engineers which pair should be used for testing. Generally, NO and NC form two pairs of lines with opposite signals to COM, and there are two power lines, red and black. After the door is opened, the closing signal becomes an open signal, and a group of opening and closing signals becomes a closing signal.

How to install the electric bolt lock?

1.Close the door first, and then use the electric bolt lock sticker delivered in the product box to stick it on the upper door frame. Or use a pencil to roughly draw the size to be installed.

2.Use a cutting machine to cut according to the hole position diagram of the sticker. Use an electric drill to perforate the wood in the door frame, and pay attention to the installation hole operation according to the size of the electric bolt lock.

3. Connect the wire of the electric bolt lock, then put the lock body of the electric bolt lock into the punched hole and fix it, and tighten the screw!

4. Align the glass door clip with the stainless steel bolt of the electric bolt lock and fix it.
