1. What is an EM Lock (Electromagnetic Lock) and how does it function?

An EM Lock is a device used to control the access through a door. The electromagnet is mounted to a door frame and the armature plate affixed to the door. When energized, the electromagnet attracts and “grabs” the armature plate with a retention force that may exceed 1000lbs., thus effectively locking the door. When input voltage is shut off, the armature plate is released thus the door is open.

2. What is the operating voltage for an EM Lock?

Electromagnets are normally operated by either 12Vdc or 24Vdc. It is extremely safe as it operates on low DC voltages. 

3. When and where to use magnetic locks?

The EM Lock has been used on almost every door and frame in almost every type facility e.g. EM Locks are ideal for interior wooden or aluminium / glass storefront type doors. When life safety is the utmost concern, EM Lock is the best locking device used.

4. What are the main criteria of selecting an EM Lock?

The main parameter to look for is power consumption and the true holding force of the electromagnet vs the armature plate. The lower power consumption the longer the backup battery would last. The higher the true holding force the better is the lock.
