Securitron Motorized Mortise Unlatch Electronic Strikes...AWESOME PRODUCT SEE BELOW
24 volts dc new in boxes, $330 a piece retail....works with all securitron keypads....two wires for current and one trip wire, easy set up
HOW IT WORKS: This latch is for mortise type doors, you DO NOT change out your mortise lock, that is the beauty, this mounts into the door frame. When activated this manipulates the mortise latch pushing it in and allowing the door to be pushed open. Door still always open from the inside, hidden, discreet and allows you to keep the traditional mortise lock without all types of electronic looking locks hanging off the door. I have these installed in my properties with securitron keypads if buyer would like a picture(100 year old victorian houses...keep the original look without adding too much technology)
