Housegard Origo™ smoke alarm When one alarm is activated, all alarms sounds. Housegard Origo™ is the new generation of intelligent smoke alarms. Origo™ is a wireless, series-connected combined smoke and heat alarm. Housegard Origo™ utilises the latest energy-saving technology, achieving a 12-month lifespan with just 2 AA batteries. When one smoke alarm detects smoke or heat, it sends a radio signal that activates all connected smoke alarms at once. The built-in localisation function tells which smoke alarm triggered the alarm. The pause function makes it possible to easily switch off the alarm in case of an unwanted alarm.
