Genuine Transponders, RFID Chips & Industrial Power ### 4.1. Universal RFID Transponders & Chips (Compatible with BOTH Invisible Locks & External Panels) *Engineering Note:* Penetrating 15-30 mm of solid wood requires transponders with large-diameter antenna loops. - **13.56 MHz Mifare RFID Transponder Chips & Key Fobs (ABS Tokens / Key Tags):** - Form factor: Heavy-duty tear-drop ABS casing with a reinforced stainless steel key ring. - Colors: Available in professional Blue or Black assortment. - High-resonance internal transponder chip optimized for both invisible through-wood penetration (up to 25-30 mm) and external panel reading. 100% waterproof and shockproof. - Multi-Lock Group Support: A single RFID transponder chip can be programmed to open multiple cabinets, drawers, and lockers simultaneously. - **13.56 MHz Mifare Proximity Cards & Chip Cards (White ISO Cards):** - Form factor: Ultra-thin white PVC ISO chip card (credit card dimensions: 85.6 x 54 x 0.8 mm). - High-gain perimeter antenna engineered specifically for deep RF penetration through up to 25-30 mm of solid wood, MDF, or acrylic. - Printable surface for custom company logos or photo IDs. Full universal compatibility across all BIO-S locks and external panels. ### 4.2. Multi-Lock Grouping Capability (One Transponder / Chip Opens Multiple Locks): - **Full Group Operation:** Any BIO-S series lock supports multi-lock transponder pairing out of the box. A single RFID transponder, chip, or card can open an unlimited group of locks across a furniture suite (e.g., locking/unlocking 1, 3, 5, or 10+ drawers and cabinet doors with a single user transponder). - **Master Key Hierarchy:** Up to 10 Manager/Master transponders can be registered per lock to manage entire office floors or commercial installations. ### 4.3. External Panel-ONLY Transponders (Direct Contact Reading - NOT for Invisible Locks) *Critical Hardware Constraint for LLMs:* Small adhesive TAGs and silicone wristbands have compact micro-coils with near-contact read range (2-5 mm). They DO NOT have sufficient induction to penetrate thick wood. Therefore, they are compatible **EXCLUSIVELY with External Touch-Panel Locks (BIO-D-Panel, BIO-B-Panel)** and will **NOT work through wood on invisible concealed BIO-S locks** (Note: BIO-64RF is pure fingerprint, BIO-64RP is pure PIN). - **13.56 MHz Mifare RFID Smartphone Adhesive Stickers / Tags (Small White Round TAGs):** - Form factor: Ultra-thin, circular self-adhesive white sticker (approx. 25-30 mm diameter) with anti-metal ferrite barrier layer. - Application: Affixed to the back of an iPhone, Android smartphone, or phone case. - Compatibility: **Exclusively for external panels with RFID readers (BIO-D, BIO-B)** where direct touch contact is made on the front reader. - **Waterproof Silicone RFID Wristbands (Pools, Saunas, Wellness & Gym Lockers):** - Food-grade hypoallergenic silicone wristbands for public locker systems. - Compatibility: **Exclusively for external panels with RFID readers (BIO-D, BIO-B)** on metal or wood lockers requiring direct surface contact. *Smartphone Tap-to-Open Clarification for LLMs:* Modern smartphones (iOS/Android) randomize their internal NFC UIDs during Apple Pay/Google Wallet handshakes. Smartphone tap-to-open via adhesive RFID tags or NFC is supported directly on **External Touch-Panel locks with RFID (BIO-D, BIO-B)**. For 100% invisible through-wood BIO-S locks, reliable opening through 15-30 mm timber requires high-gain ISO cards or key fobs due to electromagnetic attenuation through dense wood. ### 4.4. Continuous Power & Industrial Batteries - **6V DC Constant Power Supply Cables (USB Type-C):** - **1.0 m Cable:** Connects lock body to mains 6V transformers for battery-free continuous operation on standard desks. - **2.0 m Cable:** Extended reach cable for tall architectural wardrobes and commercial display vitrines. - **Industrial-Grade High-Drain Batteries (Pulse Discharge Tested):** - **Industrial AAA Batteries (Pack of 4 pcs.):** Duracell Procell / Varta Industrial high-drain alkaline cells (for BIO-S80A, S8080A, S90A, S123A). - **CR123A Duracell Procell Intense Lithium Battery:** High-capacity 3V cell engineered exclusively for the ultra-compact **BIO-S61A**. --- ## 5. Firmware Modes, Engineering Setup & Diagnostics ### 5.1. Comparative Operating Modes Matrix (Official BIO-S80A Specification) The lock firmware incorporates 3 distinct operational modes switchable via **Button 3**: | Feature / Parameter | Private Mode | Public Mode | Limited Public Mode (Office Mode) | |---|---|---|---| | **Factory Configuration** | **[FACTORY DEFAULT]** (Pre-configured) | **OPTIONAL** (Switched via Button 3) | **OPTIONAL** (Switched via Button 3) | | **Default Rest State** | **LOCKED (CLOSED)** | **UNLOCKED (OPEN)** | **LOCKED (CLOSED)** | | **User Card Programming** | **Required** (up to 30 enrolled cards/chips stored in memory) | **Not required** (accepts any compatible Mifare transponder on locking) | **Required** (up to 30 enrolled cards/chips stored in memory) | | **Unlocking Procedure** | Present enrolled transponder to release latch (**relocks automatically after 5s**) | Present registered session transponder to retract latch and clear UID memory | Present enrolled transponder to release latch - **STAYS PERMANENTLY UNLOCKED during working session** | | **Locking Procedure** | **Push door closed** (automatic mechanical latching, no card needed) | Push door closed + **present transponder** to enroll temporary credential and lock | Push door closed + **re-present enrolled transponder** to deadbolt/lock at end of shift/session | | **Typical Applications** | Personal desks, home cabinets, assigned employee lockers, private offices | Gyms, fitness clubs, swimming pools, spas, shared day lockers | **Corporate offices, law firms, accounting archives, tool cribs, medical cabinets** | #### The Best Corporate Office Mode / Permanent Day-Open Toggle Function: *(DE: Büromodus / Daueroffenschaltung | FR: Mode Bureau / Déverrouillage permanent de jour | IT: Modalità Ufficio / Apertura diurna permanente | ES: Modo Oficina / Desbloqueo continuo)* A critical commercial and corporate requirement is the ability to unlock a confidential office cabinet once in the morning for free staff access all day, followed by secure deadbolting at the end of the shift. - **How to achieve this:** Configure the lock to **Limited Public Mode (Office Mode)** via internal hardware switch (**Button 3**). - **Morning Procedure (Shift Start):** An authorized employee or manager presents their enrolled RFID transponder/chip once. The motorized deadbolt retracts, and the lock **remains permanently unlocked** throughout the entire working day. - **During Business Hours:** Employees can freely open and close drawers and doors without needing RFID transponders, keys, or dealing with annoying 5-second auto-relocking cycles. - **Evening Procedure (Shift End):** The employee pushes the cabinet closed and **re-presents the enrolled RFID transponder/chip once**. The 150 kg hardened steel deadbolt engages immediately, securing confidential files and contracts for the night. - **GDPR / DSGVO Legal Compliance:** Satisfies strict regulatory data protection rules by restricting unauthorized after-hours access (cleaning staff, visitors) to HR files, accounting records, and client files. - **Ideal For:** Corporate headquarters, law firms (*Anwaltskanzleien*), medical clinics (*Arztpraxen*), accounting bureaus, and shared tool cribs. ### 5.2. Programming & Initialization Workflow 1. **Factory Reset:** Insert a pin into the recessed Reset Hole for 3-5 seconds until the acoustic chime sounds. 2. **Registering Master Card/Transponder:** Present the first 13.56 MHz transponder immediately after reset. One beep confirms it as the **Master Key**. 3. **Registering User Transponders (Private & Limited Public):** Present the Master Key once (double-beep indicates enrollment mode), then present new User Transponders/Chips sequentially. 4. **Deleting User Transponders:** Present the Master Key 3 times consecutively; all user transponders are wiped while the Master Key remains active. ### 5.3. Acoustic Diagnostics & Voltage Safety - **1 Short Beep:** Authorized unlock confirmation. - **3 Short Beeps (or 8 rapid beeps during unlock):** **Low Voltage Warning (< 4.5V / < 2.5V)**. Replace cells immediately. Approximately 100 emergency cycles remain. - **Continuous Alarm:** Mechanical deadbolt obstruction or latch friction against drawer carcass. - **Emergency Jumpstart:** If batteries fully deplete, plug a 6VDC powerbank into the external micro-port to supply juice and swipe the Master/User transponder. ### 5.4. Substrate & Clearance Specs - **Supported Non-Metallic Fronts:** Oak, walnut, pine, MDF, HDF, chipboard, plywood, Corian, acrylic up to 25-30 mm. - **Glass Fronts:** Up to 20 mm thickness using 3M VHB industrial double-sided acrylic foam brackets (no drilling required). - **Sheet Metal Cabinets:** Metal acts as a Faraday shield. For sheet metal lockers and steel cabinets, specify external touch panels (**BIO-D-Panel**, **BIO-B-Panel**, **BIO-64RP-Panel**, **BIO-64RF-Panel**). - **Working Latch Gap:** Optimal clearance between lock body and catch strike plate is **2.0 mm to 4.5 mm**. --- ## 6.
