Kidde Fenwal 12-E27121-000-02-0T DETECT-A-FIRE Vertical Detector, 140°F (60°C), Brass Head, Close on Rise

Designed to deliver dependable actuation in life-safety and suppression systems, the Kidde Fenwal DETECT-A-FIRE vertical heat detector (12-E27121-000-02-0T) provides precise thermal sensing for both alarm and release applications. As a trusted Kidde Fenwal heat detector, it trips reliably at 140°F (60°C) using a close-on-rise contact to trigger release panels, clean-agent systems, CO2, water or dry-chemical suppression. The hermetically sealed 300-series stainless steel shell and brass hex mounting head resist corrosion and mechanical stress, reducing maintenance and extending service life in industrial, data center, and critical infrastructure environments. Its repeatable, self-restoring mechanism is testable in place, lowering lifecycle costs and downtime for security, surveillance and environmental monitoring installations. With wide spacing capability and fast response characteristics, this device optimizes coverage while simplifying system design. Ideal for integration into fire control panels and monitoring networks, the 12-E27121 is a durable, low-maintenance choice for professional fire protection.
