Intelligent Detection for Safer Facilities


By June 2022, all new system-connected smoke detectors must pass new UL 268 7th edition standards. Signature Optica is the first detector to receive certification, thanks to patented multi-criteria optical smoke sensing technology. Read the whitepaper now.


Only Signature Optica uses our patented optical sensor to differentiate between nuisance particles like cooking smoke, dust or steam, and serious hazards, only reacting to those that pose a threat. The result is a drastic reduction in nuisance alarms. Read the university housing case study now.


In addition to the state-of-the art optical sensor, Signature Optica also has models that include heat and CO sensing to cover a full range of detection applications, which means you can specify a smarter system.


You don't have to choose between compliance and cost, thanks to backwards compatible features that allow for forward migration with minimal system updates. Retrofit an existing facility without any reprogramming or rewiring and allow continuous self-diagnostics to ensure long-haul reliability.
