The WIL0010 remote radio indicator is designed to immediately signal the activation of detectors installed in inaccessible areas, such as false ceilings and floating floors, or to indicate an alarm outside the door. The device uses two-way radio communication on two redundant channels, ensuring reliability and signal continuity even in complex environments. The extended communication range, up to 200 meters, allows for flexible installation, while the standard lithium battery power supply ensures an estimated autonomy of up to 5 years, reducing costs and maintenance.
