They shouldn’t be making any sounds during normal operation – so if your light is slowly blinking, but with a sound, it’s not indicating normal operation, but something else (like a dead battery or a fire). Some models don’t even blink – they have a constant light on when they’re working fine. Normal operation is usually indicated by a green light, although there are smoke detector models that use a red light for both normal operations and raising an alarm. The good news is that normal operation is always the most likely reason for the blinking – it means that the batteries in the detector are fine and that it’s working properly. If your smoke detector blinks once a second, that’s not normal operation, that’s something else entirely. Some smoke detectors blink once a minute or once every thirty seconds. The blinking, however, shouldn’t be frequent. Many people don’t know this, but smoke detectors blink even during normal operations. Things You Shouldn’t Do With Your Smoke Detector.How Useful Are Smoke Detectors? (Statistics).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. 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. 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. 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. 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.
