![]() Browse our full range of Red smoke alarms. ![]() The detector also analyzes the smoke sensor independently from the CO sensor to determine whether to initiate a fire alarm, a life safety CO alarm, or both. Red is the only brand of smoke alarm in Australia that come with a 10 year warranty across the entire range. We also have smoke detectors, fire alarm sound effects and other tones that are perfect for. To make an alarm decision, the detector’s on-board microprocessor measures and analyzes all optical sensor readings and compares this information to preprogrammed settings.

The First Alert SC7010B Combination Smoke and Carbon Monoxide Alarm uses an advanced electrochemical CO sensor to detect elevated carbon monoxide levels from a variety of sources, such as faulty fuel-burning appliances, blocked chimneys, and cars left running in the garage. Particle data is input into digital filters which feed a series of ratios removing signal patterns that are typical of nuisance sources, thus reducing unwanted alarms. ![]() Utilizing dual optical wavelengths combined with multiple detection angles, the SIGA-OSCD differentiates particles that are not representative of actual smoke. When one alarm sounds, they all do: wireless technology uses radio frequency to both transmit and receive messages about a hazard in the home. Like all Signature Optica Series detectors, the SIGA-OSCD is an intelligent device that gathers analog information from multiple optical sensors, converting this data into digital signals. Enables quick and easy installation of an interconnected smoke alarm system without messy wiring or labor. The result is a detector that pulls double duty: continually monitoring the environment for signs of fire, as well as its invisible yet deadly companion, carbon monoxide. ![]() The SIGA-OSCD provides a combination of optical detection for the early detection of smoke, with the added element of carbon monoxide sensing. Continuous self-diagnostics ensure reliability over the long-haul, while environmental compensation helps reduce maintenance costs. The Signature Optica Series SIGA-OSCD smoke detector brings advanced optical sensing technology to a practical design that increases efficiency, saves installation time, cuts costs, and extends life safety and property protection capabilities.
