Window and door contact – optical

Open or closed – you notice it

You feel comfortable in your own home, and you should also feel safe. How about a device that not only ensures the optimum indoor climate, but also your security? Homematic IP transforms your own four walls into a feelgood oasis with unquestionable security. The window contact detects open windows, switches off the heating or, if desired, also triggers an alarm.

In combination with a Homematic IP alarm siren (e.g. HmIP-ASIR-2) your home becomes even more secure. A loud alarm is automatically triggered when a window or door is opened.
