Systems can be triggered by smoke or heat detectors or fire pushbuttons. Alarm sirens and flashing lights can also be connected. HAUTAU smoke and heat exhaust control panels operate with a 24 V safety voltage to protect both people and property. Thanks to their modular design, they offer customised control options and can be extended at any time. If repairs are necessary, modules can be replaced on an individual basis. A 72-hour emergency power supply ensures optimum safety.
