Alpro AL1982-35.5 mortice door magnet featuring 15,000N (~1,500kgf) holding force with a patented pivoting pin head mechanism incorporating integrated ball bearings for secondary locking under pressure. This Vortex magnet operates on any voltage from 12VDC to 24VDC and includes dual monitoring via two built-in SPST reed switch sensors for both lock status and door position, plus Early Warning pressure sensors that trigger an alarm before access is forced open.
The unit mortice-mounts for a fully concealed installation. The magnet body is 226mm x 35.5mm x 26.5mm and the armature plate with bracket measures 226mm x 35.5mm x 25.7mm. Wiring includes DSS (yellow, normally open), LSS (blue, normally open), and Early Warning alarm output (brown/white/grey, C/NC/NO). The built-in buzzer can be disabled via DIP switch 4. A filtered and regulated DC power source is required — the DC output must not be connected to earth ground.
About This Product
The Alpro AL1982-35.5 is a high-security mortice-mounted electromagnetic door magnet with 15,000N holding force, designed for concealed installation in commercial door frames. It is ideal for installers requiring a compact mortice magnet with comprehensive monitoring, Early Warning alarm capability and a pivoting pin mechanism that provides additional mechanical resistance to forced entry. The 35.5mm body width suits standard narrow stile aluminium door profiles.

Common Questions
- Q: Is 12VDC suitable for exit doors? A: No. 12VDC is not authorised for exit doors — use 24VDC for exit door applications.
- Q: What power supply is required? A: A filtered and regulated DC power source is required. The DC output must not be connected to earth ground.
- Q: How does the pivoting pin mechanism work? A: When external pressure is applied, the pivoting pin head initiates additional locking via upward movement of integrated ball bearings which hold the pin securely in the armature plate.
Compatibility
Suitable for mortice-type door installations. Requires filtered and regulated DC power source (12VDC or 24VDC). Compatible with remote lock and door monitoring systems via SPST reed switch outputs. Can connect to external alarm systems via Early Warning output.
