The Edwards 281B-PL heat detector provides reliable fire detection using both 135°F (57°C) fixed temperature sensing and rate-of-rise functionality. This dual mechanism allows the detector to respond quickly to sudden temperature changes while maintaining accuracy in steady heat conditions. Designed for commercial and industrial applications, the 281B-PL ensures dependable performance in critical safety systems.
The 281B-PL combines fixed temperature detection at 135°F (57°C) with a rate-of-rise sensor. Consequently, it triggers alarms when temperatures rise rapidly, even before reaching the fixed threshold. This design helps protect buildings from fast-developing fires while reducing false alarms caused by gradual temperature changes.
Edwards engineered this detector to maintain consistent performance in commercial, industrial, and utility settings. Its robust construction withstands normal environmental conditions such as dust, vibration, and humidity. Therefore, the 281B-PL remains dependable over time, supporting long-term fire safety.
The 281B-PL heat detector installs easily on standard bases compatible with Edwards systems. Its straightforward wiring and mounting reduce labor time during new installations or replacements. Moreover, integration with existing fire alarm panels is seamless, ensuring quick deployment in active systems.
Commonly used in office buildings, warehouses, and industrial facilities, the 281B-PL protects both life and property. Its dual detection method allows it to respond effectively in areas with variable temperature conditions or machinery that may generate heat.
