The door code lock of the brand Eff Eff Fritz Fuss, type 495118----93B87, is an integrated, battery-operated access control system for interior doors. It enables electronic access control while fully preserving the mechanical function of the door. From the inside, the door can be operated as usual using the door push plate. From the outside, the door push plate is electrically activated as soon as the correct code sequence is entered on the integrated keypad. Version B is specifically designed for inward-opening DIN left-hand doors or outward-opening DIN right-hand doors. The device is designed for doors with a door leaf thickness between 50 and 70 mm.

Applications

The code lock is suitable for use in residential and commercial rooms where simple but secure electronic access control is required. It is particularly suitable for interior doors where mechanical operation from the inside must remain intact, while access from the outside is controlled via an electronic code. The IP40 protection rating makes the device suitable for indoor use, where it is protected against dust and splashing water.

Functions and equipment in detail

The system features an integrated keypad on the outside, allowing up to three different, freely programmable codes to be set. Access authorization is achieved by activating the external door push plate once the correct code has been entered. The external door push plate is free-running in the locked state, preventing mechanical operation from the outside. The inside is equipped with a door push plate that can be operated independently of the electronic system. The device colour is grey-white, corresponding to RAL 9002. The door plates are prepared for interchangeable mounting elements, enabling flexible installation.

Technology explained simply

Power supply is provided by an integrated battery located inside the door plate. The electronic control is managed by an internal module that detects the code digit input via the keypad and electrically activates the external door push plate. The IP40 protection rating ensures the device is protected against dust and splashing water, which is sufficient for indoor use.

Compatibility and accessories

The code lock is designed for doors with a door leaf thickness of 50 to 70 mm. Installation is carried out using slots for drill holes of 8, 8.5 and 9 mm. The door plates are prepared for interchangeable mounting elements, enabling adaptation to various door constructions. The IP40 protection rating restricts use to indoor environments.

Installation and mounting

Installation is performed by fitting the door plates into the door leaf opening. The provided slots for drill holes of 8, 8.5 and 9 mm allow for adaptable mounting. The electronic control requires no wiring, as the device operates on battery power. Mounting is carried out without additional electrical connections, enabling simple and quick installation. The door plates are prepared for interchangeable mounting elements, allowing flexible installation on various door types.

Advantages in operation

The code lock offers simple and secure access control without impairing the mechanical function of the door. The ability to program up to three different codes enables flexible use, e.g. for different users or temporary access. Battery power ensures independent power supply, eliminating the need for additional wiring. The IP40 protection rating provides sufficient protection for indoor use. Installation is simple and does not require special tools or electrical connections.
