Johnson Controls J2351TIR
In stock!
The Johnson Controls J2351TIR is an intelligent, addressable photoelectric smoke detector from the J2351 Series with an added fixed-temperature thermal sensor, giving it combined photo-thermal detection on a single signaling line circuit (SLC) point. Dual electronic thermistors provide 135°F (57°C) fixed-temperature heat detection alongside the photoelectric smoke sensing element, and the detector reports continuous sensitivity data back to the panel so drift and contamination can be tracked over time rather than discovered only at the next test.
Key Features
- Combined photoelectric smoke and 135°F (57°C) fixed-temperature thermal detection in one head
- Panel-programmable sensitivity with continuous sensitivity monitoring
- Rotary decimal addressing for point identification on the SLC
- Remote test capability via panel command or local magnet test
- Enhanced optical sensing chamber tuned to detect a broad range of combustion sources
Technical Specifications
- Detection: Photoelectric + 135°F (57°C) fixed-temperature thermal
- Addressing: SLC addressable, rotary decimal
- Mounting: Plug-in intelligent detector head
Certifications
- UL 268 7th Edition compliant optical sensing chamber
