The Double Series Electromagnetic Locks operate with holding forces from 500kg up to 1160kg. Covering a range of applications these magnets are ideal for applications from access ways through to high use commercial swing doors. With fixing options including wood, aluminium and steel constructions, as well as glass door applications, the range caters to most electromagnetic needs.

  • Fail-safe: unlocks when power is removed
  • Easy installation: suitable for both new and retrofit usage
  • High holding force: refer to the technical data overleaf
  • Self-alignment: armature plate pivots to accommodate door drop
  • Silent operation: no humming or buzzing
  • Dual voltage: site selectable 12 or 24 Vdc
  • Monitoring; Hall-Effect and Reed Switch monitoring on all models
  • Instantaneous release: Smart electronics on the Z Series electromagnets eliminate residual magnetism.

Applications

  • Aluminium doors
  • Double swing doors
  • Access control
  • Surface mount for inswing and outswing doors

Hall / Bond Monitoring
This indicates that the lock is powered and that the armature plate is in position and magnetically bonded (it monitors if the magnet is locked)

Reed switch monitoring
An integrated reed switch monitors the door position separately (it monitors the position of the door)

Standards and Compliance

  • Successfully fire rated up to 4hrs on fire door assemblies in accordance with AS1905.1. 2005 (Part 1: Fire resistant door sets)
  • CE Approved
  • C-Tick Certified

Holding force is measured directly between armature and magnet, holding force on the door may vary depending on the leverage created.

Specification Statement

The Double Series Electromagnetic Lock should be constructed in an aluminium base with heavy duty electromagnet. The range only operates in fail safe mode and relies on a secondary lock or battery backup system. The lock needs to be equipped with "smart electronics" that have zero residual magnetism, (instantaneous release). This is crucial for correct operation.
