Combination lock with proximity reader VIDOS ZS40B — keypad and RFID access control

VIDOS ZS40B is a combination access control lock that integrates a numeric keypad with a proximity RFID reader. Designed for managing authorised entry in residential and small commercial settings, the unit accepts PIN-code entry and proximity card or tag authentication for reliable two-mode access. Its compact housing and modular interface make it suitable for mounting on doors, gates or controlled entry points where straightforward user management and secure operation are required.

Advantages

The device supports both keypad PIN entry and RFID proximity identification, enabling flexible access control workflows. A single unit replaces separate card reader and keypad installations, reducing wiring and installation complexity. The construction is intended for regular pedestrian access, providing simple user enrolment and routine operation while maintaining consistent authentication methods. The design emphasises compatibility with common access control systems and straightforward integration into existing door hardware.

Suitable for

• Residential apartment building entrances and individual flats
• Small offices and commercial premises with moderate visitor flow
• Gated entries and utility rooms requiring controlled access
• Shared facilities where PIN and RFID combination enhances convenience

Key specifications

• Access modes: numeric PIN code and 125 kHz proximity (RFID) credentials
• User interface: illuminated numeric keypad for code entry
• Mounting: surface-mount suitable for doors and gateposts
• Power and connectivity: low-voltage supply and standard access control wiring (power and signal lines)
• Operating environment: designed for indoor and sheltered outdoor installation

How to use

Install the unit on the door or gate according to the mounting instructions and connect power and signal lines to the access control panel or lock mechanism. Program user PIN codes and register proximity cards or tags through the device programming interface or the connected access control system. To open, present a registered proximity credential to the reader or enter a valid PIN on the keypad; the unit will verify the credential and trigger the lock release when authentication succeeds. Regularly test functionality after installation and after any configuration changes.

Usage recommendations

Place the unit in a sheltered location if installed outdoors to protect the keypad and reader from direct weather exposure. Maintain a log of issued proximity credentials and periodically update or remove unused PINs and cards to keep the authorised user list current. Use appropriate surge protection and ensure wiring follows local electrical and safety codes to maintain reliable operation.
