The System Sensor 5603 is a precision 135°F fixed temperature heat detector designed for comprehensive fire detection in commercial and industrial environments. Engineered for reliable thermal sensing, this detector provides critical early warning in spaces where rapid temperature rise indicates potential fire conditions, such as mechanical rooms, warehouses, manufacturing facilities, and electrical infrastructure areas.
Compatible with addressable and conventional fire alarm control panels, the 5603 heat detector offers professional-grade thermal sensing technology. Its fixed temperature design triggers an alarm when ambient temperatures reach 135°F, making it ideal for environments with moderate heat exposure and specific fire risk profiles. The robust construction ensures consistent performance across challenging commercial installation scenarios.
