Mag locks, strikes and exit doors

Electric strike or mag lock?

An electric strike replaces the frame strike and lets the mechanical hardware (lever, panic bar) work normally on exit. A mag lock holds the door magnetically and needs extra release devices. Where possible, we prefer a strike.

Exits must always open

A door on an egress path must open from inside without a key or special knowledge. With a mag lock this generally means release on fire alarm, on power loss and by a manual device near the door, per the Code and occupancy.

What we check

• Occupancy type and door role (exit, access, service)
• Fire alarm interface
• Power-loss behaviour (fail-safe or fail-secure)
• Exit button or sensor, existing panic bar
• Local fire-prevention requirements

Our role

Altea installs this hardware under an RBQ licence and coordinates with the electrician, the fire alarm provider and, if needed, the architect. Exact requirements depend on the building: this guide doesn’t replace the authorities having jurisdiction.
