System Sensor 4WTR-B Fire Alarm Smoke + Thermal Detector

The System Sensor 4WTR-B combines smoke and thermal detection to provide comprehensive fire safety monitoring. It integrates a dual-sensing mechanism that enhances early warning capabilities in diverse environments.

• Dual sensing technology merges photoelectric smoke detection with heat sensing to reliably identify fire conditions.
• Wide voltage compatibility supports a range of 15 to 32 VDC, allowing seamless integration with existing fire alarm systems.
• Built-in fixed temperature rating at 135°F enhances detection of rapid temperature rises indicative of fire.
• Compact design enables easy installation in tight spaces without sacrificing performance.
• UL listed and compliant with industry safety standards ensures trusted operation in commercial and residential applications.

Compared to earlier models, the 4WTR-B offers improved detection accuracy through its combined smoke and heat sensing technology, reducing false alarms while increasing responsiveness. Its compatibility with a broad voltage range and streamlined form factor set it apart within the fire safety product category.

Enhanced Detection and Reliable Performance

The advanced dual-sensor system of the 4WTR-B significantly boosts its ability to detect both smoldering and flaming fires. This integration helps address scenarios where smoke or heat alone might not trigger an alert promptly, offering a more robust safety net for occupants.

With a fixed temperature threshold at 135°F, the thermal detector component responds swiftly to rapid heat changes, complementing the smoke sensor’s sensitivity to airborne particles. This twofold approach minimizes delays in fire identification and maximizes occupant safety.

The device’s design supports straightforward installation and maintenance, reducing downtime and ensuring continuous protection. Its UL listing confirms adherence to rigorous testing and quality standards, making it a dependable choice for fire detection systems across various settings.
