Are mag locks fail-safe or fail secure?
Electromagnetic locks are only available fail safe—there is no magnetic bond when power is removed. Fail secure products are more common than fail safe due to security concerns. Power consumption may also be an issue. Fail secure products provide security when there is no power applied.
What is the purpose of a mag lock?
A maglock is an electrified locking device that uses low-voltage power to keep an entrance secure. Also referred to as an electromagnetic lock or magnetic lock, they consist of an electromagnet and an armature plate.
Do fire alarms unlock doors?
These products ensure that the doors can be unlocked automatically upon fire alarm or by a signal from the fire command center and that they remain latched as required for fire doors. The method of release — fire alarm or signal from fire command center — varies depending on which code is being used.
What causes a mag lock to stick?
When a power supply isn’t properly grounded, the maglocks become “sticky”. As in, it takes a brief moment to drain off the residual voltage.
Are magnetic locks safe?
Direct pull electromagnetic locks are inherently fail-safe. Typically the electromagnet portion of the lock is attached to the door frame and a mating armature plate is attached to the door. The two components are in contact when the door is closed.
What is the difference between electric strike and mag lock?
The primary difference between electric strike locks (door strike) and magnetic locks (maglocks) is their power requirement. Maglocks are fail-safe, while electric strikes are generally fail-secure. In other words: Magnetic locks require power to lock the door, whereas electric locks require power to unlock the door.
How do electromagnetic fire doors work?
Electromagnetic Fire Door Holders The magnet holds onto the keeper plate in the fire door’s open position. The magnet is wired to and powered by the fire alarm panel and is automatically switched off in case of fire, releasing the fire door and allowing it to close.
