Corrosion Resistance: Rolled steel housing and aluminum components resist oxidation in outdoor settings

and floating point or On/Off signals

Engineered for high-temperature furnace environments

Bypassing a safety limit switch is never recommended for permanent operation

Fenwal 12-H27121-000-08 Sensor Refrigerant Corrosion Resistance: Rolled steel housingThe Fenwal 12 H27121 000 08 Detect A Fire Sensor is a high precision, rate compensated temperature sensitive fire detector engineered for critical vertical mount applications. Designed to activate at a fixed thermal set point of 600F, this unit operates with a Close on Rise contact action, completing the circuit to trigger fire suppression systems or alarms when the threshold is reached. Built with a 300 stainless steel shell and a hex brass mounting
