2. Hardware Overview & Components
Standard Set Contents (Included in Each Package):
-
Electronic RFID Cabinet Lock BIO-S123A: Slim Lock Body with Motorized Latch Tongue + Door Strike with Integrated Spring-Loaded Ejector Pin
※ Standard factory configuration: each RFID cabinet lock is pre-programmed out-of-the-box to operate in Private Mode. -
Two Pre-Configured Proximity RFID Credentials (13.56 MHz Mifare):
- 1× Manager Proximity Card: Dedicated administrative programming key
- 1× User Proximity Card: Operational credential for daily unlocking
- Complete Fasteners Set: Complete set of hardened mounting screws (4 screws for lock body + 3 screws for strike) for quick installation in wooden, MDF, or metal cabinetry.
2.1 Lock Body Specification
Material: High-impact ABS polymer shell.
Dimensions: 123 × 59 × 19.5 mm (slim vertical architecture).
2.2 Motorized Latch Tongue & Spring Ejector Strike
The BIO-S123A employs an advanced two-part locking mechanism designed to provide smooth electronic latching and automatic door release:
- Motorized Latch Tongue (Lock Body): A solid, motorized deadbolt latch tongue that extends directly from the lock casing into the strike. When an authorized Mifare RFID credential is presented, the internal motor smoothly retracts the tongue into the body to release the door.
- Strike Hook with Integrated Spring Door Ejector (Door Mount): Mounted directly on the door using 3 screws. The strike features an integrated spring-loaded plunger pin (Ø4 mm). When the door is closed, this pin is depressed against the cabinet wall; when the lock tongue retracts, the spring pin automatically pops the door open (1–2 cm) for effortless access without requiring external handles.
2.3 Proximity Credentials (Cards, Fobs, Bands)
Diverse form factors of 13.56 MHz Mifare RFID credentials supported: waterproof silicone wristbands, robust ABS key fobs (teardrop/oval), ISO rectangular cards, and adhesive tokens.
2.4 Fasteners & Screws Specification
Corrosion-resistant, hardened installation screws provided for diverse cabinet substrates: 4× screws for securing the lock body firmly to the cabinet partition and 3× screws for securing the strike hook to the door front.
2.5 External Power Interface & 6V USB-C Power Supply
Equipped with an integrated emergency backup port. Compatible with external battery boxes and emergency power adaptors to supply temporary 6V power if internal batteries are completely exhausted.
Optional Continuous Power Supply: In addition to standard battery operation, every BIO-S123A invisible cabinet lock can be continuously powered via an optional external 6VDC switching power supply with a 1m USB Type-C cable (available separately as an accessory).
* Note: The external 6V USB-C switching power supply is not included in the standard set.
To guarantee 100% operational reliability and prevent electronic latch failure through 25mm timber panels, only and exclusively install brand-new, fresh alkaline batteries from a professional manufacturer – INDUSTRIAL Grade (e.g., Varta Industrial Pro, Duracell Procell / Industrial, Energizer Industrial).
STRICTLY PROHIBITED:
• NO rechargeable NiMH batteries (1.2V): Total voltage of 4× 1.2V is only 4.8V, which immediately triggers premature low-voltage alarms.
• NO zinc-carbon or low-cost supermarket consumer batteries: They lack the high peak discharge current (up to 200mA) required to reliably actuate the motorized latch tongue.
• NO mixing of old and new batteries: Always replace all 4 batteries simultaneously with fresh cells from the same production batch.
3. Product Installation Dimensions
Lock Body Dimensions (4-Hole Mounting)
- Outer dimensions: 123 mm (L) × 59 mm (W) × 19.5 mm (H).
- Mounting screw holes: 4 corner mounting holes arranged for ultra-rigid fastening to the cabinet partition.
- Motorized latch tongue extension: 11.5 mm projection beyond the casing edge.
Strike Dimensions (3-Hole Mounting with Spring Ejector)

6.1.1 Mode Overview: The lock remains latched under Private Mode. Only enrolled User Cards can unlock the cabinet. Upon swiping a valid card, the motorized latch tongue retracts into the casing, the spring ejector pushes the door open, and the tongue automatically re-extends after 5 seconds, allowing the door to be pushed shut securely into the strike plate.
6.1.2 Set Lock into Private Mode:
🛡️ 6.1.3 Registering New Manager Card (Programming Authority)
In Private Mode, the Manager Card is used strictly to authorize the enrollment of new User Cards.
🔑 6.1.4 Registering New User Card(s) (Up to 30 User Credentials)
User Cards are the daily credentials used to unlock the cabinet.
6.1.5 How to Use User Card:
6.1.6 Registering Delete Card (Batch Clear All Users):
Presenting the Delete Card immediately revokes all 30 registered User Cards simultaneously.
6.2.1 Mode Overview: The latch tongue remains retracted inside the casing under Public Mode. Any customer can access a free locker. Presenting any Mifare credential extends the motorized latch tongue into the strike plate to lock the door, and only that identical credential will retract it to unlock. Once unlocked, the locker is instantly released for the next guest.
6.2.2 Set Lock into Public Mode:
🛡️ 6.2.3 Registering New Manager Card (Emergency Master Key)
In Public Mode, the Manager Card acts as an emergency master override allowing facility staff to unlock the locker if a guest misplaces their credential.
🔑 6.2.4 Registering New User Card (Automatic Guest Locking)
No pre-enrollment required! Under Public Mode, any unregistered Mifare card or wristband presented by a guest will automatically drive the motorized latch tongue into the strike plate to lock the door. That exact same credential is then required to retract the tongue and unlock it.
6.2.5 How to Use (Locking & Unlocking Workflow):
6.2.6 Registering Delete Card (Clear Current Locker):
Presenting the Delete Card immediately frees the locker by clearing the active guest card's assignment.
6.3.1 Mode Overview: The lock begins in a locked state. Once unlocked by an authorized user card, the motorized latch tongue remains continuously retracted throughout the working day. When the employee is ready to lock up, they push the door shut and present their user card again to extend the latch tongue into the strike plate.
6.3.2 Set Lock into Limited Public Mode:
🛡️ 6.3.3 Registering New Manager Card
🔑 6.3.4 Registering New User Card
6.3.5 How to Use User Card:

7. Reset Lock (Restore Factory Defaults / Public Mode)
When the Reset button is pressed and held for 2 seconds:
- ALL CREDENTIALS ARE PERMANENTLY DELETED: Every registered User Card, Manager Card, and Delete Card is erased from internal non-volatile memory. All previously programmed cards become completely invalid.
- LOCK RESTORES FACTORY DEFAULT PUBLIC MODE: The invisible RFID lock immediately restores its standard factory state (Public Mode – default tongue retracted state). If you wish to use the lock in Private Mode, you must explicitly program it into Private Mode as outlined in Section 6.1.2 before registering daily user credentials.
8. Essential Operational Guidelines & Best Practices
- When the indicator light flashes in blue, it indicates battery capacity is critically low. Replace with fresh INDUSTRIAL alkaline batteries immediately.
- System memory capacity per lock: 10 pcs Manager Cards, 10 pcs Delete Cards, and 30 pcs User Cards.
- Always install brand-new, premium professional batteries of the INDUSTRIAL grade (e.g. Varta Industrial Pro, Duracell Procell). Expected battery lifetime: 6–12 months. Never mix old and new cells.
- Verify full lock actuation, ensure battery installation, and enroll all credentials BEFORE physically mounting the lock into the furniture!
- Automatic Door Ejection: The BIO-S123A door strike features an integrated spring-loaded ejector pin (Ø4 mm) that automatically pushes the door open (1–2 cm) as soon as the motorized latch tongue retracts. Ensure that the strike is mounted with its 3 screws firmly secured and aligned so the ejector pin depresses smoothly without snagging.
