SURE SG660 Mini Door Alarm - Specification

Who is this Suitable for?

This alarm is a discrete, magnetic contact alarm and will provide door/window security. You can apply this unit to any door, window, filing cabinet or anywhere where contact can be broken. Once contact is broken, the alarm will siren.

On/Off switch. Siren to warn off unwelcome visitors or chime to alert occupier. Supplied with batteries fitted.

We also target this alarm to the care home market. Dementia care can be particularly difficult, dementia causes a lot of confusion for the person suffering and unfamiliar surroundings can cause a patient to want to escape that environment. Door chime alarms will alert carers to their attention and therefore potentially save someone's life if they were to leave their home in a state of confusion. 

Why You Need an Alarm

Alarms work in two main ways. Firstly, burglars are often looking for the opportunity to break-in. Window alarms are often seen as a visual deterrent making the prospect of breaking in less attractive. Secondly, if a burglar does attempt to try their luck the alarm will sound alerting people nearby and potentially spooking the potential thief.


To activate the alarm, move the side switch to either the 'ALARM' or 'CHIME' position depending on your preference (located on the side of the device). When the door or window is opened and the alignment between the alarm and sensor is broken, the alarm will sound immediately. The alarm will disarm when the door or window is closed or if the alarm is switched to the 'OFF' position

This unit is supplied with three 1.5V LR44 batteries. If the alarm or chime tones diminish, please change the batteries immediately.


Simply remove the double-sided tape from the rear of the alarm and mount it to a window or door. Repeat the procedure with the magnetic sensor. Please make sure that the alarm and sensor are aligned correctly and are no more than a quarter of an inch apart.
