Addressable combined photoelectric smoke + heat detector with an intelligent smoke–heat combined algorithm; dual-wavelength smoke sensing reduces false alarms.
Key features
- 2-wire non-polarized connection; highly reliable smoke–heat combined algorithm that uses both parameters for accurate fire judgment.
- The smoke part uses dual-optical-path, dual-wavelength technology, distinguishing steam from dust and reducing false alarms.
- The heat part uses an epoxy-encapsulated sensor with good insulation and high reliability.
- Self-diagnosis of key components; drift compensation and dust-contamination alarm.
- RF interference immunity (RS) 30V/m; unique ID code; twist-lock blind-mate structure.
