When the lock is Alarmed a single Bleep will be heard. Once armed it has a unique program that controls the sensitivity, this is very important, as you don’t want it going off all the time when its windy, our locks are designed with a unique microchip that controls the sensitivity, There are similar looking products on the market but none that have this technology built in. The lock has three sensitivity levels LOW-MED-HIGH.
When it is in alarm mode, if there is any slight wind movement the alarm will not sound, the control unit can recognize tampering and innocent movement i.e. wind conditions, if tampered with, the lock will sound 3 ear piercing bleeps and automatically increase sensitivity, if tampered again within 1-30 seconds just even a slight movement or any foreign metal contact on the shackle will immediately sound a 10 second 110db alarm. After the 10 second alarm has sounded the lock will be in a high alert state (maximum sensitivity) for 30 seconds and will repeat the 10 second alarm if tampered again and thereafter will drop sensitivity one level at a time after it has sensed no movement for 30 seconds. This unique technology ensures no false alarms.lock designation. The lock is designed for many applications.
