This electric bolt lock has been designed with double-swinging doors in mind.   In most cases, doors open one-way and close firmly into the frame, however when you have a double-swinging door which opens both ways with nothing to firmly stop it in the closed position, electric solenoid bolt locks fall short in terms of their suitability for this scenario. 

This electric lock however, incorporates a simple but very clever and useful roller-ball in the face of the lock.  This acts as a rollerbolt for double-swing doors, allowing the door to actually have a stopping point the lock will work at, rather than swinging freely back and forth when the door is left to close.   The roller ball is situated in an adjustable housing, allowing you to make modification to suit the width of the gap between your door and the frame, making it a very versatile and well thought out feature to this lock. 

In addition to this, the magnet on the keep plate is also adjustable to work in a similar fashion.  As the read range on the magnetic sensors cannot exceed 5mm, this adjustment allows you to use these locks on doors where perhaps the distance you have between the door and the frame can be compensated for. 

These are a fail-safe solution, so they draw power to lock, and in the event of power failure will allow the door to be opened.  At 12v DC the current consumption to fire the bolt out is 900mA, and once this has been done, the consumption is reduced to just 300mA in 'holding mode' to keep the bolt thrown. 

What's more, these solenoid bolts also offer monitoring.  This monitoring output comes from the magnetic reed in the lock detecting the magnetism of the adjustable magnet on the keep.  When the magnetism is firmly detected and then the bolt is fired into the keep, the monitoring relay output changes state to allow you to remotely view whether the door is closed or open, by taking these monitoring outputs and feeding them to a monitoring system or even a basic set of LED lights to demonstrate open / closed status. 

On the side of the lock case you will see some dip switches.  Using the instructions on the lock (pictured in the photos on this page), you can set the auto-relocking timer to 0, 3, 6 or 9 seconds.    This is the time delay between the firm detection of the magnetism between the lock and the keep, and the actual firing of the locking bolt into the keep.
