AV2 lock picture

Most door sets are now 3 point locking doors. To get these to work electronically through remote control or intercom you replace the existing locking system with the electronic motor driven lock version and replace the outdoor handle and your ready to operate.  As soon as the door is closed, automatic locking takes place with 2 high tensile steel hooks engaging without the need to lift a handle. The locked door can then be open internally by depressing a handle or operating a thumbturn cylinder. Entrance is gained by use of a key or remote electronic device.

Our engineers have installed 100s of AV2E locks and are highly trained. These locks can be linked through an intercom and an overhead automatic door closer. Visitor calls to the entrance of your business/property and uses the intercom to call the in. You pick up the handset and speak to the tenant and grant them access to the building through your composite door its never been easier.
