Welcome to the Nano Range of Detectors brought to you by Cavius, perfect for securing your home. Cavius alarms are Danish-designed and constructed by British engineers to provide the perfect safety equipment. Furthermore, every alarm is assembled by hand to add a personalized touch. The Nano Range Smoke Alarm is the world's smallest thermal heat alarm, but it does not compromise on quality. Advanced technology is packed into this tiny thermal heat alarm to ensure safety throughout your home. The Photoelectric sensor takes a reading every 8 seconds to detect any unusual readings, triggering the alarm stage when necessary. It's easy to get your home installed with smoke alarms, but with rooms such as kitchens, garages, and laundries it can be much harder. Cavius makes security easy, with the Nano Thermal Heat Alarm. This alarm detects changes in ambient room temperature and sound, alerting when there is a rapid and consistent temperature increase, or when the temperature exceeds 58oC. This allows for added safety measures, in areas that would be previously unmonitored. In addition to these impressive features, the Nano Range Thermal Heat Alarm is the smallest heat alarm in the world, measuring only 40mm. The Nano Range Thermal Heat Alarm is installed with a 3v Lithium Battery, for 10 years of stable power. When the battery starts to run low, there's no need for concern about a surprise outage. The Nano Range Thermal Heat Alarm has an inbuilt low-battery alert that will blink for 30 days to remind you of the maintenance required. Installation is easy, and adaptable, as the Nano Range Thermal Heat Alarm can be installed as either recessed or flush into your ceiling, to best suit your existing decor. Important: This Alarm does not meet Queensland Regulations. Check with your local electrician to see if this alarm is suitable for your state's standards.
