Specification Statement
The Single Series Electromagnetic Lock should beconstructed in an aluminium case with heavy dutyelectromagnet. The range only operates in Fail Safemode and relies on a secondary lock or battery backupsystem. In some cases the Magnet Armature Plate pivotsto accommodate door drop. The lock needs to beequipped with “smart electronics” that have zero residualmagnetism (instantaneous release). This is crucial forcorrect operation.
