Monitoring Option – Armlock 281-005 model has built-in monitoring (hall effect) and relay dry contact with LED.

Versatile Compatibility – Works with access control systems and can be released by keypads, card readers, and push to exit buttons. For immediate release, the release switch needs to break the circuit on the positive supply to the magnet.

Mounting Accessories Available – Compatible with a range of brackets for tailored installation. As standard, this lock suits outward opening doors. Use compatible Z and L brackets for inward opening door installation.
