Optica duct detectors feature a unique design that speeds installation and simplifies maintenance. Separate sensing and control sections, optical sensing tube, conformally coated circuit boards and hydrophilic coatings keep contaminants away from sensitive electronics providing longer service life. When cleaning is required, the assemblies come apart easily and snap back together in seconds.
The optical sensing tube incorporates many of the same principles used in in the Optica detector. This sensor inherits the power and benefits of this exceptional technology.
Optica duct sensors gather analog information from their smoke sensing elements and convert it into digital signals. The sensor measures and analyzes these signals and compares the information to historical readings and time patterns to make an alarm decision. Digital filters and algorithms remove signal patterns that are not typical of fires, which reduces unwanted alarms.
