GEM SB260 Electric Solenoid Bolt Lock with Euro Cylinder Override

One of the most distinct advantages with this electronic bolt lock is that it has the ability to be overridden by a key or thumbturn euro cylinder.  This allows you to make use of a euro-profile cylinder to facilitate key-override to gain access via a key, and also gives you the ability to offer a free-egress solution by utilising a cylinder with a thumb-turn on the inside. 

The bolt on these electric locks is an impressive 16mm thick, and with a decent 16mm bolt projection into the keep, these will offer a good level of security to your door whilst allowing you to control access with an access control solution. 

Featuring adjustable auto-relocking time settings, by simply tweaking the jumpers on the lock body (pictured in the photos above), you can set the lock to auto-relock after 3 seconds, 8 seconds, 15 seconds or 25 seconds. 

The sensor magnet on the keep is also fully adjustable.  Simply by loosening the nut on the back of the magnet (behind the keep plate), you can then reposition the threaded magnet in or out by simply rotating it clockwise or anti-clockwise until the adjustment suits your particular installation.  It is however always best to try to fit the keep plate at the most accurate distance possible in the first instance to ensure you are maximising on the bolt projection available from the lock into the keep plate.

These electric locks operate on 12v DC but can also self-regulate voltage anywhere from 12v up to 28v (still DC of course).  With a maximum current draw of 900mA when retracting the bolt from its keep, a 1Amp power supply would suffice for the lock alone; and once retracted, they draw a much lesser 300mA to maintain the open state for the duration of the hold-open specified by the auto-relocking timer setting on the lock body.  However if you plan on powering other devices from the same power supply you would need to go higher depending on the overall consumption of all of your devices. 

These are a fail-secure solution, so in the event of power failure the door will not open, for this reason we would recommend a power supply with a backup battery to ensure you do not immediately loose operation in the even of a power cut.  Additionally a thumbturn cylinder would be useful here should your power be offline long enough for the battery to wear down, so exiting through the door can still be achieved.

A euro cylinder is not supplied but we have options below for high security euro cylinders offering key one-side for key ovveride from one side of the door, key both sides for offering key override on both sides of the door, a key & thumbturn cylinder offering free egress to exit and key override from outside, as well as a thumbturn-only option for if you wish to provide free egress without offering key override from outside. We have chosen the high security EPS cylinder range as the best solution for these locks due to the quality of this electric lock.
