Description
The System Sensor 5602 is a dependable mechanical heat detector from the trusted 5600 Series, engineered to deliver fast and accurate thermal detection in a wide range of commercial and residential fire protection applications. With a single-circuit design and dual-mode alarm capability, this detector provides a robust first line of defense against heat-related fire hazards.
Key Features
- 194°F (90°C) fixed heat alarm point for reliable high-temperature detection
- Rate-of-rise alarm condition detects rapid temperature increases for early warning
- Single circuit configuration for straightforward wiring and integration
- Lettering identification method for easy field identification and installation
- Part of the proven 5600 Series mechanical heat detector family
- Mechanical design requires no external power for heat sensing — inherently reliable
Dual Detection Technology
The 5602 combines two alarm methods in one compact unit. The fixed heat alarm triggers when ambient temperature reaches 194°F, while the rate-of-rise feature activates when temperature climbs rapidly — even before the fixed threshold is reached. This dual-mode approach helps minimize response time and reduces the risk of property damage.
Easy Installation & Identification
The lettering identification method allows technicians to quickly identify and document detector locations during installation, inspection, and maintenance. The single-circuit design simplifies wiring runs and reduces installation time on new and retrofit projects.
Ideal Applications
- Commercial buildings and warehouses
- Residential garages and attic spaces
- Areas where smoke detectors are not suitable due to dust, steam, or fumes
- Locations requiring supplemental heat detection alongside existing fire alarm systems
