Kidde-Fenwal 27120-0-325

The Kidde-Fenwal 27120-0-325 is a DETECT-A-FIRE heat detection and release device designed for fire suppression system initiation. This rate-compensated thermal detector operates at a 325°F (163°C) temperature setpoint and features a vertical configuration with normally-closed contacts, triggering clean agent, CO2, or inert gas suppression systems when ambient temperatures exceed the preset threshold.
