Designing and installing electronic access control across commercial, public, and healthcare buildings presents unique hardware challenges. Architectural trends lean heavily toward frameless glass, narrow-profile aluminium transoms, and high-traffic timber fire doors. At the same time, security managers demand high holding forces, reliable fail-safe egress, and clear visual status indication.

Traditional face-to-face electromagnetic locks (maglocks) can often feel like a aesthetic compromise. Standard surface magnets can be bulky, intrusive on clean door lines, susceptible to side-load jamming, and energy-intensive. Fortunately, specialised manufacturers like Alpro Architectural Hardware (a division of IEC Limited) have engineered innovative solutions that combine compact dimensions, hybrid mechanical-magnetic holding power, and clever mounting accessories.

In this guide, we take a practical look at how specifying Alpro surface magnets and specialised glass door mounting clamps can solve complex access control challenges while maintaining high physical security and building compliance.


Overcoming Space & Security Constraints: The Alpro Vortex AL2400 Surface Magnet

When securing high-traffic perimeter or interior doors, standard face-to-face electromagnetic locks rely solely on magnetic force. To achieve a high holding force (such as 500kg to 1500kg), conventional magnets require large, heavy housings that overhang narrow door transoms and draw substantial electrical power.

The Alpro Vortex AL2400 reimagines electromagnetic locking by introducing a patented hybrid mechanism that blends magnetic holding force with mechanical locking strength.

How Hybrid Locking Works

At the heart of the Vortex AL2400 is a conical aperture set within the compact magnet body, which receives a high-strength alloy swivel pin mounted on the armature plate. When the magnet is energised, the armature plate is drawn tightly against the magnet face, and internal steel locking elements engage with the pin head.

This hybrid interaction provides several distinct specification advantages:

  • 1,500kg Holding Force in a Streamlined Body: Despite delivering an independently tested holding force in excess of 1,500kg (approx. 15,000N), the Vortex AL2400 housing is up to 75% smaller than conventional high-security magnets, measuring just 218mm long and 36mm high.
  • Guaranteed Side-Load Release: A common vulnerability with standard maglocks is "side-load pressure" - where physical pressure applied to the door (e.g. someone pushing against it while activating an exit sensor) causes the armature plate to stick. The Vortex AL2400 is engineered to release cleanly even under a side-load pressure of up to 100kg when power is cut, ensuring fail-safe egress compliance.
  • Lower Carbon Footprint & Energy Consumption: Consuming up to 50% less power than traditional face-to-face alternatives (drawing just 240mA at 12V DC or 120mA at 24V DC), the unit reduces overall power supply requirements and thermal output.
  • Triple Monitoring & Early Warning Alarm: Built-in sensors monitor lock status (Hall effect) and door position (reed switch). Additionally, an integrated pressure contact can trigger an early warning alert or local sounder if unauthorised force is applied before the door is opened.
