A 500kg magnetic lock provides a holding force equivalent to approximately 1,200 lb-force, which exceeds the force that can be applied to a door by most individuals without mechanical assistance. For access-controlled entrance doors, this holding force is the standard specification for residential and commercial single-door applications where the door is not regularly subjected to determined forced entry.
Failsafe operation means the maglock releases when power is interrupted. For doors on emergency evacuation routes, fire compartment boundaries, and any door that must be freely openable in an emergency, failsafe is the required configuration under fire regulations and building safety standards. The access control system keeps the lock energised during normal operation; a fire alarm trigger or power interruption causes the lock to release and the door to be free-opening.
12/24V DC operation provides compatibility with the power supply units used across the access control and security industry, without requiring a dedicated voltage specification.
The LED indicator on the lock body provides a visual status indication: the LED state (on or off) identifies whether the lock is energised and holding or de-energised and released, which is useful during commissioning and for door status monitoring.
For access control installers completing single-door magnetic lock installations on commercial and residential properties across London and the UK where 500kg failsafe operation with LED status is the specified hardware, the STP MG-500-LK provides the standard maglock unit.
