Electronic lock CH4 encryption

Key Features

1. Multifunctional access control - PIN codes, 125 kHz proximity cards, as well as operation mode as a controller or Wiegand reader.

2. Supports up to 10,000 users - Perfect for home and corporate facilities.

3. High resistance and durability (IP66) - Waterproof and durable housing allows installation outdoors - in rain, frost and heat, without the risk of damage.

4. Touch-sensitive, backlit keyboard - Comfortable code entry in the dark thanks to the backlight that automatically activates when touched.

5. Advanced security - Possibility to mask the PIN up to 10 digits, alarm after incorrect attempts and anti-sabotage protection.

6. Flexible relay configuration - Select pulse (e.g. 5 s) or toggle (ON/OFF) mode, matching the operation to the given electric lock.

7. Possibility of connecting an exit button (REX) - Easy exit from the room from the inside without using a PIN or card.

8. LED and buzzer indication - A colored LED and sounds inform about each status of the device - opening, error, alarm or programming.

9. Quick Card Add Mode - When this feature is enabled, each card presented automatically opens the door and registers as a user - ideal for mass card issuance.

Access control system connection description

The diagram shows the connection of the 12V power supply, electric lock, exit button, bell and Wiegand inputs.

1. Power supply

• DC+ (red) – +12V
• GND (black) – ground Powers the controller and lock.

2. Electric lock

The controller provides a relay output:

• NC (orange) – for fail-safe locks (e.g. magnetic, opens after a power failure)
• NO (blue) – for fail-secure locks (electric strikes that open when powered). The lock uses the same 12V power supply. A 1N4004 diode is recommended.

3. Exit button

• OPEN (yellow) – button signal
• COM (purple) – ground Allows the door to be opened from the inside.

4. Bell

• Doorbell+ (gray)
• Doorbell – (Brown) When connected, allows you to trigger a sound upon entry.

5. Wiegand input

• D0 (green)
• D1 (white) For connecting an external card reader or keyboard.

6. Other uses

The relay output (NC/NO/COM) can also control a gate, automatic door, solenoid valve or other device requiring an impulse.
