Product Description P/N: 12-E27121-000-04
Description
The Fenwal 12-E27121-000-04 is a DETECT-A-FIRE® rate-compensated heat detector designed to initiate an electrical signal when its sensing element reaches a factory-set 190°F (88°C) operating point. Fenwal part number 12-E27121-000-04 uses a close-on-rise SPST contact, vertical mounting configuration, and hermetically sealed stainless-steel construction for fire alarm, suppression release, and industrial overtemperature applications.

Information About 12-E27121-000-04
The 12-E27121-000-04 is a Fenwal DETECT-A-FIRE rate-compensated thermal detector engineered to respond at a predetermined temperature during both gradual and rapidly developing heat conditions. Its self-restoring sensing mechanism is factory calibrated for 190°F operation and closes the internal electrical contact as temperature rises to the activation point. The detector combines a 300-series stainless-steel shell with a hexagonal brass mounting head and hermetically sealed contact area to resist vibration, shock, contamination, and demanding industrial environments. It can be integrated into compatible fire alarm or suppression systems for detection, signaling, or release functions involving clean agents, CO₂, water, dry chemicals, and other approved extinguishing arrangements.
Key Features:
- 190°F operating point: Factory-set to activate at a nominal temperature of 190°F (88°C).
- Close-on-rise contact: SPST electrical contact closes when the detector reaches its calibrated activation temperature.
- Rate-compensated detection: Responds to the actual thermal condition while compensating for different rates of temperature increase.
- Self-restoring operation: Automatically resets after the sensing element cools below its reset threshold and requires no replaceable thermal element.
- Fast-response configuration: Designed with a fast Response Time Index for prompt reaction to developing overtemperature conditions.
- Vertical mounting: Configured specifically for installation in the designated vertical orientation.
- Stainless-steel shell: 300-series stainless construction provides mechanical durability and resistance to demanding environments.
- Hermetically sealed contacts: Internal switching components are isolated from moisture and environmental contamination.
- Brass mounting head: Hexagonal brass head provides a rugged mechanical interface for installation.
- White identification coding: White color coding identifies the specified 190°F temperature configuration.
- Shock and vibration resistance: Rugged construction supports operation in industrial machinery and equipment environments.
- Fire suppression compatibility: Suitable for alarm initiation or release-control applications in properly engineered fire-protection systems.
The 12-E27121-000-04 delivers the reliability and precision required for fixed-temperature fire detection, suppression-system initiation, and industrial overtemperature monitoring.
