The Hochiki ALO-V is an analog addressable photoelectric smoke detector certified to UL 268 7th Edition. Its chamber uses IR and blue LED light sources with multi-spectrum smoke categorization to detect smoldering and flaming fires from traditional materials and polyurethane while resisting nuisance alarms from cooking. It suits open areas and is also suitable for monitoring smoke in HVAC ducts.
