Description
The Fenwal 12-E27121-020-05 is a Detect-A-Fire fixed-temperature heat detector engineered for reliable, precise thermal detection in demanding commercial and industrial HVAC and fire protection applications. Featuring a 225°F (107°C) actuation temperature with a close-on-rise operating principle, this detector responds when ambient temperatures reach or exceed the set point — making it ideal for environments where heat buildup signals a critical condition.
Key Features
- 225°F (107°C) fixed actuation temperature — close on rise operation
- Fast Response Time Index for rapid detection of thermal events
- +7°F / -8°F tolerance for consistent, repeatable performance
- Vertical mount configuration for flexible installation
- Hex 300 Series stainless steel mounting head for corrosion resistance and durability
- 300 Series stainless steel shell for long-term reliability in harsh environments
- White color coding for quick visual identification of temperature rating
Construction & Materials
- Mounting head: Hex 300 stainless steel — resists corrosion and mechanical stress
- Shell: 300 stainless steel — suited for high-humidity and chemically aggressive environments
- Color coding: White — industry-standard color for 225°F rated detectors
Application
The Fenwal Detect-A-Fire series is widely used in commercial kitchens, mechanical rooms, industrial process areas, and other locations where reliable fixed-temperature detection is required. The fast response time index ensures early actuation, helping to minimize equipment damage and protect personnel. The stainless steel construction makes this unit suitable for corrosive or washdown environments where standard detectors may fail prematurely.
