Strengthen your home’s door and window security with these small, but mighty sensors. You’ll always know if an entrance is exposed. Accidentally left a door or window open? Potential break in? Your sensors are on it. They’ll immediately send a wireless signal to your HC24 App, triggering a high-decibel alarm that you — and any intruders — won’t miss. You’ll also receive an instant security alert on your smartphone via the HC24 App.

The HC24 Door/Window Contacts are installed on common intrusion points such as windows and doors to provide perimeter protection of the premises. The HC24 Door/Window Contacts are designed to communicate with the security system to report openings and closings of doors & windows. Known for its versatility and reliability, the contact is an easy to install device ideal for a wide range of environments. 

The HC24 Door/Window Contacts features an auxiliary input that can be used to easily connect a standard hardwired contact. The auxiliary input can be configured to be Normally Open, Normally Closed or Single End-of-Line. This feature is useful in installations where space is of a premium and it is difficult to mount the magnet within the maximum allowable gap of the contact.

Home security tip: Our Door & Window Sensors are so small and versatile, many HC24 customers find other great uses for them: like securing kitchen & medicine cabinets, jewelry boxes — virtually any enclosure you want to protect from snooping hands.
