Description
The Fenwal 12-E27120-022-05 Detect-A-Fire heat detector switch is a factory-preset thermal safety device engineered for dependable overheat and fire detection in industrial, commercial, and HVAC safety systems. Designed for vertical mount applications, this rugged switch reliably opens its internal contact when the ambient temperature reaches approximately 225 °F (107 °C) — helping trigger alarms, equipment shutdowns, or fire suppression systems before conditions worsen.
Key Features
- Engineered for Safety: Detect-A-Fire technology provides accurate thermal response and dependable switch action to help protect people and equipment in critical environments.
- Factory-Set Temperature Rating: Precisely calibrated to 225 °F (107 °C), the sensor opens its normally-closed contact on temperature rise to signal overheat or fire conditions.
- Vertical Mount Design: Hex head allows easy vertical mounting in tight mechanical or electrical cabinets, HVAC systems, or fire detection circuits.
- All-Stainless Steel Construction: Durable 300-series stainless steel shell and head stand up to harsh environments and resist corrosion, shock, and vibration.
- Normally Closed (NC) Contact: Internal switch stays closed in normal conditions and opens on temperature rise, making it ideal for fail-safe detection and control loops.
- Wide Use Compatability: Contact ratings (typically up to ~5 amps) work with many alarm panels, control relays, and safety shutdown circuits.
