❓ Frequently Asked Questions
What is a "Fail-Safe" lock?
A fail-safe lock is designed to unlock automatically when power is removed. This ensures that in the event of a power outage or fire alarm, doors will open to allow safe egress.
How does the time delay function work?
The "T" and "ST" models include an adjustable timer (0-20 seconds). Once the door is closed, you can set a specific delay before the magnet re-activates and locks the door.
Can I monitor the door status remotely?
Yes, models with the "S" suffix (Signal Output) provide NO/NC/COM wiring, which can be connected to access control systems or alarms to monitor whether the door is currently locked or unlocked.
Which holding force should I choose?
The choice depends on the door type. 180kg is suitable for small cabinets or light doors; 280kg is standard for office doors; while 350kg and 500kg are recommended for heavy-duty or high-security commercial doors.
What door materials are these locks compatible with?
These electromagnetic locks are highly versatile and can be installed on wooden doors, glass doors (with U-brackets), metal doors, and fireproof doors.
Does the lock support 24V DC systems?
Yes, the locks are designed to support both 12V and 24V DC power inputs, making them compatible with most standard security power supplies.
