What is the difference between Monitored and Unmonitored Maglocks?

The monitored option for a Maglock means that the magnet has an output that will allow you to connect it to an external device e.g a beacon, sounder or integrate into an alarm to monitor the status of the Maglock - either locked or unlocked.

Unmonitored Maglocks do not have the facility to wire in monitoring. There is no indication of whether the magnet is locked or unlocked.

What is the difference between Swing Free & Hold open?

When an electromagnetic door control is set as SWING FREE the door will act as if no door closer is fitted and once triggered by the fire alarm it will pull the door closed from any position. Swing Free is commonly used on bedroom doors in care homes where a low door opening resistance is required.

With HOLD OPEN functionality the door is held at 90 degrees and when triggered by the alarm system will pull the door to the closed position. Hold open is commonly used in high traffic areas such as corridors.

Why do I need battery backup in a Power Supply?

What is the difference between a sashlock and a deadlock?
