This brilliantly designed alarm has been created to help prevent Sneak-In theft, particularly prevalent during warm summer months but is suitable for many uses all year round. Simply fit over the internal door handle and if anyone touches the outside handle, the alarm sounds inside! There is even an exit delay when setting it so that you have time to leave the premises before it arms.
There are many uses for this alarm, for example, for anyone who leaves their door unlocked but would want to know if somebody entered. This can also be adapted to use on a push bar door.
Highly suitable therefore for students – backpackers – nursing staff – elderly or infirm and even travelers staying in hotels, etc. however please note that they are not suitable on metal or composite type doors.
