Z-18 can be used on cylinder-operated mortises (deadbolt and daytime bolt will be retracted). Do you have a cylinder-operated multipoint safety system in your door? No problem, the Z-18 will retract deadbolt and daytime bolt, and safety latches as well.
If you have a standard mortise in your door, then only the deadbolt will be retracted. It functions the same as your mechanical key: you unlock the deadbolt and then push the handle down to retract the daytime bolt.
Z-18 is powered by 4 CR123A Li batteries which are included in a package. There are also 2 pcs of card key hangers and a cylinder with backup keys.
Remove the old cylinder and place the new cylinder, then fix the Z-18 to the door. It is a quick and easy installation, we can say "almost everyone" can do it. Once the system is installed, just start the app and determine the turning direction of your door, set it in the app, and voila, you are ready to register fingerprint, make codes, and register cards.
Weather protection: IP65 or higher. It can be used outside for entry doors.
