Digital Numeric Keypad System C-3830

A keyless system with numbers that change positions and are easy to see even at night.

■Easy Wiring Wiring from the controller to the operation unit, electric lock, and operation display is simple, requiring only two wires connected in a non-polarized manner. Additionally, the keypad, which is often installed outdoors, is designed to be JIS rainproof. ■Scramble LCD Keypad with Rotating Number Sequence The positions of the numbers change with each operation, making it difficult to detect the PIN. This scramble-type LCD keypad is self-illuminating, ensuring reliable operation even in dark environments. ■Setting and Changing the PIN via LCD Screen and Setting Button The setting and changing of the PIN is done through the LCD screen and setting button on the controller. The PIN can be registered with up to 8 different 4-digit combinations. ■Clear Icon Display for Operational Status The icon display on the controller's LCD screen and error codes allow users to check the status of the electric lock and door, as well as the type of error that occurs during a malfunction. ■Alarm Buzzer Effective Against Tampering and Unauthorized Entry If the keypad is unnecessarily pressed four times in succession, an alarm buzzer will sound, helping to prevent tampering and unauthorized entry. Additionally, the design allows for partial disarming of security devices in case of emergencies.
