CDVI Magnetic Locks

CDVI magnetic locks hold doors secure as part of an access control system. The page has surface and mortice maglocks, including 500kg and 180kg models, a magnetic pull handle and a transom housing that carry two 300kg magnets apiece, a fail-safe magnetic door holder for fire doors, a shearlock surface housing and fitting parts such as a Z&L bracket, an armature housing, a mimic handle and a cover strip.

Choosing CDVI Magnetic Locks

Choose by holding force, by where the lock is fitted and by whether you need status monitoring.

Maglocks

The S500-MI is a 500kg electromagnetic lock that comes with brackets for mounting. The I500ER is a stainless-steel mortice maglock with 500kg holding force for exterior and harsh environments; it runs on 12–24 V DC, has monitored NO/NC outputs for access control panels and is fail-safe, unlocking on loss of power. The V1SR is a surface-mounted lock with 180kg holding force, 12 or 24V DC operation, live status monitoring and LED indication, and it is packed with safety cables so the magnet cannot fall out during installation.

Handles and housings

The BO600RP is a 2500mm architectural pull handle with two 300kg monitored magnets, for new or existing wooden, metal or glass doors; it can be used externally and cut down to size. For a double-action swing door, the PRP-800 is a mimic handle for the non-magnetised side, so users can pull from either direction. The BO800-C25 is a BO800 cover strip for architectural maglocks, sold as a 25 metre length. The AH3-22HM is a 2m transom housing fitted into the door frame, mounted horizontally and supplied with two 300kg electro-magnetic locks.

Brackets and door holders

The 500-ZL Z&L bracket mounts CDVI 500kg internal surface maglocks on inward- or outward-opening doors and adjusts in depth between 50.5 and 101 mm. The AMA3 is an aluminium surface housing for the armature plate of CDVI 300 kg locks, for door leaves where recessed fitting is not possible. The VIRA5024 is a wall-mounted, fail-safe magnetic door holder for fire doors with 50 kg holding force on 24 V DC and a manual test release button.

Frequently asked questions

What is a CDVI magnetic lock?

A CDVI magnetic lock is an electromagnetic door lock made by CDVI, an access control manufacturer, for securing doors on controlled entrances. Versions include surface, mortice and handle-mounted designs, and some report door status back to the access control panel. Holding force is quoted in kilograms, so match it to the door's security needs. The range here includes maglocks, pull handles, housings and brackets.

How does a CDVI maglock work?

A CDVI maglock works by passing current through an electromagnet that clamps a steel armature plate fixed to the door. When the access control system or an exit button cuts the power, the magnet lets go and the door opens. Maglocks are typically fail-safe, so they unlock on loss of power, which suits escape routes. Monitored versions can also signal whether the door is secure.

Can a CDVI maglock be used outside?

Yes, some CDVI maglocks and magnetic handles are made for external doors. Look for a stainless-steel or weather-resistant body and check the ingress rating before fitting one outdoors. A mortice maglock recessed into the frame also gives a neater, harder-to-tamper-with finish. The range here includes a stainless-steel mortice maglock for exterior doors and a pull handle rated for external use.
