Magnetic lock vs electric strike: choosing a lock for access control

Two main types

• Electromagnetic lock (maglock) holds the door only while powered. This is fail-safe: the door releases on power loss.
• Electric strike / bolt lock can be fail-safe or fail-secure; a fail-secure lock stays locked without power.

How to choose

1. Escape routes generally require a fail-safe solution.
2. Server rooms, stores and rooms with valuables often use fail-secure.
3. Glass doors need dedicated brackets.

Safety elements

Install an exit button and an emergency break-glass release on the inside, and integrate the system with the fire alarm so doors unlock during an alarm. Use a power supply with battery backup.
