Heat detector C9021T

temperature risefor fire safety applicationsfor indoor use

Product name
Conventional heat detector C9021T

Key features

• Two-wire, non-addressable switch-type temperature sensor compatible with conventional fire panels.
• Upper and lower cover design for easy installation, commissioning and maintenance.
• Real-time ambient temperature monitoring to detect rapid or fixed temperature rises.
• Non-polar wiring for straightforward field connection.

Applications
Point-type C9021T heat detector is designed for detection of fires that generate significant heat (volume heat), suitable for industrial and civil locations such as kitchens, boiler rooms, generator rooms, drying plants and smoking rooms. Not recommended for environments with smoldering fires, low-heat fires or where smoke detection is required.
