Product Description P/N: 12-E27121-020-04
Description
The Kidde-Fenwal 12-E27121-020-04 is a DETECT-A-FIRE temperature sensor with a factory-set 190°F (88°C) activation point and normally-open contacts that close on temperature rise. Its rate-compensated thermal design is intended for fire detection, alarm initiation, and activation of compatible suppression systems.

Information About 12-E27121-020-04
The 12-E27121-020-04 is a Kidde-Fenwal DETECT-A-FIRE Model 27121-20 temperature sensor configured for vertical mounting. Its rate-compensated operating principle responds to surrounding air temperature while maintaining effective response under both gradual and rapidly developing thermal conditions. The detector incorporates a 300-series stainless steel shell and stainless steel hex mounting head, with its internal contact area hermetically sealed from the surrounding environment. The normally-open switching configuration closes at the nominal 190°F threshold and is suitable for initiating alarms or controlling compatible clean-agent, CO2, water, and dry-chemical suppression equipment.
Key Features:
- 190°F Activation Point: Factory-set to operate at a nominal temperature of 190°F (88°C).
- Close-on-Rise Operation: Normally-open contacts close when the specified thermal threshold is reached.
- Rate-Compensated Detection: Responds to surrounding air temperature while accounting for different rates of temperature increase.
- Vertical Mounting: Model 27121-20 is specifically configured for vertical installation.
- Stainless Steel Hex Head: Uses a 300-series stainless steel mounting head for durable installation.
- Stainless Steel Shell: Incorporates a 300-series stainless steel outer shell with a hermetically sealed contact area.
- Temperature Tolerance: Rated at +7°F/-8°F relative to the nominal activation temperature.
- Self-Restoring Design: Provides repeatable thermal operation without requiring replacement after normal testing or activation conditions.
The 12-E27121-020-04 delivers the reliability and precision required for temperature-based fire detection and suppression-system initiation.
