Window contact switch with radio transmission DIBt tested including external antenna

Why does a chimney go “upside down”? A kitchen hood or toilet fan draws exhaust gases from the chimney into the apartment. This cannot be allowed and must be prevented. People must not be put at risk.

The combustion ordinance (FeuV § 4 Installation of fireplaces) stipulates that when a room air-dependent fireplace (e.g. fireplace, stove, gas boiler) and exhaust fans (e.g. extractor hood) are operated at the same time in an apartment/house, it must be ensured that no carbon monoxide is removed from the fireplace.

As soon as an exhaust system is switched on, a negative pressure is created in the closed room. Pressure equalization may then only take place via the flow of fresh air from outside and not via the fireplace . This is reliably guaranteed by the exhaust air safety switches, as the extractor hood only starts operating when the window is open.

The window contact switch with radio transmission can be easily retrofitted. No cable needs to be laid later. You are protected quickly and easily from the extractor hood not drawing harmful exhaust gases out of your fireplace or stove. The external antenna is already included and mounted.

Install the radio receiver practically as an adapter plug between the socket and the extractor hood and attach the window monitor (transmitter + magnetic contact) to the window. The exhaust system now only switches on when the magnetic contact on the window has been interrupted, i.e. H. the window has been opened or folded.

This radio safety switch is of course DiBT certified (DIBt approval no. Z-85.2-5).

Low susceptibility to interference thanks to adjustable radio frequencies. High reliability thanks to microprocessor technology in the control unit as receiver and window monitor.
