Cisa 11921 Series Electric Lock for Metal Doors and Gates

Another very popular version of the Cisa range of electric rim locks. This version is primarily designed for gates and door where the rear of the door is also exposed to the weather as the locks body has been galvanised.

Apart from the electrical activating of this lock it also sports a cam cylinder that projects out of the back of the lock 50 mm that would be able to go through the gate or door to allow the user to open the lock from the non secure side. In addition to this, this lock also has a cylinder that works on the same three keys on the inside. So you can mechanically override the lock from the inside. Be mindful this version has no red button on the inside so the only way to open the lock from the inside without the key is electrically.

These locks are handed and you will see on the page a handing chart showing the options. Be mindful that these differ to the way the UK hands locks. So please check for the handing you have prior to purchase.

Connecting power to these locks is normally done through the door from the hinge side. We show an option of a door loop on the page if needed but we also are able to offer the Cisa Current Transfer Unit, which can be used either on the hinge-side or the opening side of the door if you already have power there from an old strike release or similar.

We also show a power supply. These locks are quite power hungry compared to some locks and require around 2.5 amps to drive the solenoid bolt. So we have listed also a 3 amp power supply if needed.  Please note that if integrating with an intercom or similar, if the system does not offer "dry" volt-free contacts then you'll need to consider using the Handy Relay we offer also. 

In addition to the options you will also see a London Bar that can be fitted over the keep in the frame (inward opening only) and this will 'beef' up the security of the keep on the frame.

The size of the body on these locks are 125 mm Long, 35 mm deep and approx 102 mm high. This lock does not come with fixings.
