Discover a solid and convenient way to effectively secure and easily control access to your door. The Spreest electronic lock combines high-quality workmanship (metal, waterproof IP66 housing) with modern RFID identification technology (EM 125 kHz cards) . Thanks to the autonomous operation and operation of the Master card , configuration and permission management are intuitive and simple in everyday use. This compact controller fits perfectly on the door frame, allowing safe entry into both your home and your business, warehouse or other facility. Key Features 1. Standalone access control: No additional control units required – all settings and data are stored in the device itself. 2. Waterproof, metal housing (IP66): Perfect for outdoor use, guaranteeing resistance to rain, moisture, and various weather conditions. 3. Supports 3000 cards: Large user capacity – ideal for companies, warehouses or facilities with many employees or guests. 4. Included administration card (Master Card): Allows you to quickly and intuitively add or remove access authorizations, without complicated programming. 5. Latch mode: Allows you to keep the door constantly open (e.g. when bringing in goods or during maintenance work). 6. Tri-color LED indicator: Quickly informs you about the current status of the device (red/yellow/green), so you know whether the lock is locked, in programming mode or unlocked. 7. Wide connection possibilities: The device can work with various types of power supplies (9–24V DC), electric strikes (NO/NC), and also cooperate with exit button (REX) – this guarantees flexibility of installation in various facilities. 8. Safety of use: The lock has built-in safeguards (including a 1N4004 diode) protecting against surges . You can safely use the device in professional access control systems. IP66 Waterproof The IP66 waterproof housing provides reliable protection against rain , moisture and dust , making it an excellent choice for mounting on external door frames. Thanks to the solid metal construction and special seals, the device remains fully functional regardless of the prevailing weather, guaranteeing safety and continuous operation. Wiring Diagram The device supports many functions thanks to its simple and flexible connection options. Below is a description of each wire, its symbol, and its application — for both standard and specialized power supplies (access control power supply). Lock wire description: Yellow — OPEN — Request to Exit button input (REX) — Allows the door to be opened from the inside. Red — 12V — Device power supply 9-24V DC (typically 12V DC) Black — GND — Ground / Common to power and relay. White — NO — Normally Open relay contact — Used e.g. for NO type electric strikes Brown — COM — Common relay line — Necessary when connecting devices to NO or NC Green — NC — Normally Closed relay contact — Used e.g. for NC type electric strikes Example of use The device allows you to control various access control elements: Exit button (REX): When pressed, opens the door from the inside – convenient in offices, warehouses, etc. → Connected to the OPEN (yellow) connector. Power supply: Can be connected to a standard 12V DC power supply or a special access control power supply (DC 12V/3A). → 12V (red) and GND (black) connectors. Electric Strike: The device opens the lock after reading a valid card or fingerprint. → Connection via NO (white) and COM (brown). Electric Lock / Electric Latch (Electric Bolt): Used for glass or metal doors – works in closed mode. → Connection via NC (green) and COM (brown). Important *If you connect a standard power supply to the , it is mandatory to install a 1N4004 protection diode (included in the package). This protects the device from damage. *When using the specialized access control power supply , the diode is not necessary and the connection is made directly to the appropriate power supply terminals (NC, NO, COM, PUSH etc.). Thanks to this universal scheme, the device can be used both in simple home installations and in professional access control systems in companies , warehouses , schools and other facilities .
