Fenwal 12-E27120-000-03 Detect-A-Fire
The Fenwal 12-E27120-000-03 Detect-A-Fire is a high-precision thermal fire detector engineered for rapid response in critical hazard environments. This vertical mount unit features a 160°F temperature rating with an open on rise contact configuration, making it a standard choice for fire suppression system activation. Built with a rugged 300 stainless steel shell and a hex brass mounting head, this sensor utilizes rate-compensation technology to provide an accurate Quick Response Time Index, outperforming fixed-temperature detectors that suffer from thermal lag. The black color coding ensures easy identification of its 160°F operational threshold. Designed for intrinsic safety and reliability, it is highly resistant to shock and vibration, allowing for repeatable and self-restoring performance without the need for replacement after testing or accidental activation. This unit is essential for monitoring overheating and fire hazards in industrial settings using CO2, clean agent, or dry chemical extinguishants.
Key Benefits for Contractors
- Rate-Compensation Technology: Eliminates thermal lag by reacting to the rate of temperature rise, ensuring the Fenwal 12-E27120-000-03 activates precisely at its set point.
- Self-Restoring Design: Unlike one-time fuse links, this vertical thermal sensor resets itself after the ambient temperature drops below the set point, allowing for easy system testing.
- Durable Construction: The 300 stainless steel housing and hex brass head provide superior corrosion resistance in harsh mechanical environments.
- Precise Tolerance: Features a factory-set tolerance of +7°F / -8°F, ensuring consistent performance in high-risk zones.
- Cost-Efficient Layouts: Engineered for wide spacing, reducing the total number of units required for full area coverage in a fire protection system.
Common Questions
What does 'Open on Rise' mean for the Fenwal 12-E27120-000-03?
In an 'Open on Rise' configuration, the electrical contacts remain closed during normal operating temperatures and open when the ambient heat reaches the 160°F set point, typically used to trigger an alarm or release mechanism in specific circuit designs.
Can this unit be mounted horizontally?
The 12-E27120-000-03 is specifically designed as a vertical mount sensor. For horizontal applications, a different model suffix is required to ensure the rate-compensation mechanics function according to factory specifications.
How do I identify the temperature rating in the field?
This model features black color coding on the head of the unit, which is the industry-standard identifier for Fenwal detectors rated at 160°F.
