Kidde Fenwal 27120-22 Vertical DETECT-A-FIRE Detector, Normally Closed (Open on Rise), Stainless Steel

Protect critical assets with the Kidde Fenwal 27120-22 Vertical DETECT-A-FIRE heat detector — a proven, industrial-grade detector that delivers dependable, early heat detection and precise activation of fire suppression. The D-A-F’s rate-compensated sensing accurately monitors ambient temperature changes, providing faster, more reliable response than fixed-temperature or simple rate-of-rise devices. Built in a stainless steel vertical housing and configured Normally Closed (opens on rise), this detector offers rugged durability and positive supervision for integration into clean agent, CO2, inert gas, or water-based suppression systems. Ideal for data centers, engine rooms, process areas and other high-value environments, the 27120-22 minimizes false alarms from transient thermal gradients and reduces unnecessary downtime and service calls. As part of your security and monitoring strategy, this Kidde Fenwal heat detector supports effective fire detection and suppression activation while simplifying system commissioning and maintenance. Specify the 27120-22 for reliable thermal monitoring in commercial and industrial fire protection systems — contact us to discuss application fit or order today.
