Product Overview & Technical Specifications
The ALSL-800 series is engineered for commercial, healthcare, and industrial sliding door assemblies requiring positive, unassisted latching upon closure. The internal spring-loaded trigger bolt automatically engages the strike plate the moment the door reaches its fully closed position, securing against unauthorized entry or pressure differentials.

Product Selection Guide (How to Specify)
Selecting the correct lock variant depends on door weight, operational frequency, and life-safety compliance requirements.
Step 1: Determine Activation Mode
• Mechanical Auto-Lock: Operates via physical trigger paddle; suitable for standard compartmentalization and cleanrooms.
• Fail-Secure / Fail-Safe Electronic Integration: Integrates with access control systems (24V DC / 12V DC solenoid release) for secure facilities and data centers.
Step 2: Verify Door Material & Weight
Recommended for metal-framed glass doors, heavy wooden core sliding doors, and stainless steel cleanroom panels up to 250 kg per leaf.
Step 3: Select Finish Options
Brushed Stainless Steel (US32D / EN 1.4301)
Satin Nickel (US15)
Matte Black Powder Coat (AAMA 2604 compliant architectural finish)
Industrial Application Scenarios
The ALSL-800 mechanism is validated for environments demanding rigorous hygiene, constant cycling, and structural integrity:
Cleanroom & Pharmaceutical Facilities: Maintains airtight seals on cleanroom sliding doors by resisting positive/negative pressure differentials up to 50 Pa without disengaging.
Healthcare & ICU Units: Provides silent, automated latching for patient room sliding doors, integrating emergency manual thumbturn override for medical staff.
Commercial Data Centers & Server Rooms: Pairs with electronic access control triggers to restrict entry to server corridors while ensuring rapid egress compliance.
Supplier Manufacturing & Quality Control Capability
Engineering teams require verifiable quality parameters. Our production infrastructure ensures batch-to-batch dimensional stability:
Raw Material Traceability: Spectrometric chemical analysis performed on every incoming lot of SUS304 stainless steel and zinc alloy ingots prior to machining.
Machining Precision: CNC multi-axis milling centers maintain internal locking tolerance windows within +/-0.02 mm, preventing binding and premature mechanical wear.
Surface Treatment: Automated multi-tank electroplating and passivation lines ensure uniform corrosion resistance layers across all internal springs and latch bolts.
Rigorous Testing Protocols: 100% of production units undergo functional torque, stroke distance, and latch engagement testing on automated pneumatic test jigs before packaging.
Certifications: ISO 9001:2015 quality management system certified; material test reports (MTR) provided upon request per EN 10204 3.1.

Frequently Asked Questions
Q: What prevents the auto-locking mechanism from failing if the sliding door is slammed shut repeatedly?
A: The internal latch bolt incorporates a high-tensile stainless steel damping spring and an inertial counterweight designed to absorb impact energy. It is cycle-tested at velocities up to 1.5 m/s without structural deformation of the catch pin.
Q: Is field-reversibility supported for left-sliding and right-sliding doors?
A: Yes. The modular cassette design allows technicians to reverse the trigger orientation and latch bevel on-site using a standard hexagonal key, reducing SKU inventory requirements for distributors.
Q: What documentation is provided for architectural submittals?
A: We supply complete technical submittal packages including 2D/3D CAD drawings (DXF/STEP), installation instruction sheets, finite element analysis (FEA) load reports, and raw material certificates (EN 10204 3.1).
Q: Can the locking mechanism be integrated with fire alarm systems for emergency egress?
A: Electronic variants (ALSL-800-E) support fail-safe operation. Upon receiving a dry-contact signal from the fire alarm panel (loss of power), the internal solenoid unlocks instantly, allowing manual sliding egress regardless of mechanical auto-lock settings.
