The 932091E is an electrically-triggered, high security door strike featuring mechanical switch function (keeps unlocked on latch), for use with the 2N range of IP-addressable Door Entry Systems. This version of the lock is opened by 12v supply, but will stay open until the door is closed again. Connected to a 2N Door Intercom or Access Control device, the 932091E can be controlled from a remote location via a LAN, WAN or web connection. This allows a visitor to communicate with a specific resident or (for example) with a remote security office, who can trigger the locking mechanism via an IP device connected to the same network, such as an IP telephone.
