Get the peace of mind you deserve from the knowledge that you'll be notified immediately should a door or window be opened unexpectedly in your home. The Household Door/Window Alert Sensor works by sending a wireless signal to the Household Alert Receiver (sold separately as 70-525), which in turn notifies you immediately of the breach with both audio and visual indicators.
