Description
Reliable Perimeter Protection with the Avl-St-160 N412G 12V DC Mortice Electric Release
Managing physical security across busy commercial spaces, educational facilities, or multi-tenant residential buildings often involves balancing convenience with robust property protection. Traditional mechanical latches require constant key management, which can lead to lost keys, unauthorised duplicate copies, and regular maintenance bottlenecks. When you need to upgrade an entrance to electronic access control without tearing out existing woodwork or replacing complete door leaf systems, selecting the right mortice strike is critical to maintaining day-to-day building safety.
The Avl-St-160 ( N412G ) 12V Dc Mortice Electric Release Grey Fail Locked provides a dependable, electro-mechanical solution designed specifically for standard mortice latch configurations. Operating on a smooth 12V DC direct current supply, this unit integrates seamlessly with intercoms, digital keypads, biometric readers, and push-button exit systems. Its fail secure architecture guarantees that if power is cut or an electrical failure occurs, the internal keeper stays firmly locked, safeguarding your internal spaces against unauthorised physical intrusion.
Finished in an understated industrial grey, this mortice release blends cleanly into both timber and metal door frames. Backed by the technical hardware expertise at Doorfit, this versatile strike is engineered to handle consistent, high-frequency pedestrian traffic while preserving the structural integrity and aesthetic lines of your current architectural joinery.
Step by Step Implementation and Operational Workflow
Frame Preparation and Mortice Rebate
Initial installation begins by marking out the door frame rebate to match the dimensions of the release faceplate. Wood chisels or dedicated router cutters allow tradespeople to prepare a flush cavity within timber frames. The compact footprint preserves frame strength, making the Avl-St-160 ( N412G ) 12V Dc Mortice Electric Release Grey Fail Locked suitable for retrofitting older latch locations cleanly.
Low Voltage Wiring and Circuit Setup
Power cabling feeds through the back of the frame rebate into the terminal block. A steady 12V DC filtered power supply must be used to eliminate mechanical hum and ensure clean release cycles. Connecting through relays on access controllers or push-to-exit buttons allows the internal solenoid to energise instantly when release signals trigger.
Keeper Engagement and Latch Alignment
Once secured within the jamb, the mechanical latch bolt of the door locks directly against the internal pivoted keeper. Installers should verify that the latch sits fully home without excessive side pressure. Accurate alignment ensures that the door does not rattle while preventing mechanical friction that could bind the release mechanism during electronic activation.
Commissioning and Ongoing Operational Safety
System commissioning involves testing access credentials, key switches, and mechanical key overrides. The fail secure design ensures continuous perimeter defense during unexpected mains outages. Simple periodic inspections of keeper clearance and screw fixings will keep the hardware functioning reliably for thousands of opening cycles across demanding workplace settings.
Key Operational Advantages
Selecting the right electric release means balancing security requirements with long-term mechanical dependability. The Avl-St-160 N412G provides several practical benefits that simplify both installation and everyday management.
- Fail Locked Engineering The unit requires an active 12V DC signal to unlock, making it the ideal choice for secure stockrooms, back offices, and exterior access doors where unauthorised entry must be prevented during power failures.
- Quiet Direct Current Solenoid Unlike AC buzzers that produce a loud hum during operation, the DC coil operates quietly and smoothly, making it suitable for professional corporate reception areas and quiet clinic corridors.
- Durable Grey Protective Coating The tough factory-applied grey finish provides outstanding corrosion resistance against damp British weather while presenting a tidy modern appearance against dark or painted timber frames.
- Universal System Compatibility Designed to work alongside conventional access panels, telephone entry systems, digital coded keypads, and standard request to exit buttons.
- Mechanical Override Capability When paired with a compatible mortice nightlatch, authorised keyholders can easily override the door mechanically from outside using a standard cylinder key during emergency conditions.

Important Installation Advice
Please ensure that the Avl-St-160 N412G release is supplied using a dedicated, smoothed 12V DC power pack. Supplying alternating current or unfiltered rough power can cause solenoid damage over time. Additionally, verify that the door closer is properly regulated so the latch enters the strike jaw smoothly without exerting continuous side load on the internal release mechanism.
