My SK605 door / window alarm goes off when I close my window or door, not when I open it

We have seen a defect in a small percentage of SK605 entry alarms, where the functionality is reversed: The alarm is triggered when the contacts are brought together, not when they are separated. This is a production error. It has affected a very small number of units, but we are aware of it.

If you have purchased a SK605 that is exhibiting this behaviour, please return it to your point of purchase for an exchange.

If you are unable to return it to your point of purchase, contact us with your proof-of-purchase, and we will send a replacement.

We sincerely apologize for this inconvenience, but remain committed to providing top-notch customer service.
