Electronic lock handle S4A-M10 TTLock
The S4A-M10 electronic lock handle by Spreest is a clever solution that will allow you to turn an ordinary door into a smart access point, where you can let your guest in in a second with a one-time code , give the cleaning crew access without stress "for tomorrow 10-12", and after closing the door, the lock automatically closes - all without the need to take the keys out of your pocket.
It is ideal for Airbnb rentals, self-check-in hotels, warehouses or offices , where guests can be remotely sent a code or e-key valid only during specific hours.
Automatic locking after closing the door eliminates the risk of leaving the door open, and the built-in memory supports 100 fingerprints and 150 PIN codes – plus unlimited e-keys in the app.
No internet? No problem – the handle works locally and stores user data internally.
The external panel is IP65 certified , so there is no problem with mounting the handle on entrance doors exposed to weather conditions.
The batteries last for about a year. When the battery starts to run low, the lock will warn you, giving you time to replace it.
The handle fits left and right doors with a thickness of 35–55 mm – wooden, steel or aluminum.
