It combines fixed-temperature and rate-of-rise thermal sensing technologies to deliver early detection of rapid heat changes associated with fire conditions. Using rotary dials for addressing, the sensor communicates precise temperature and alarm data digitally through the panel’s signaling line circuit (SLC). Its low-profile, ivory-colored housing provides a clean, unobtrusive appearance suitable for commercial and institutional installations. Although discontinued by the manufacturer, the ATD-RL2F remains a key component for maintaining existing Velociti-based fire detection systems. Key Features: Dual Detection Technology: Combines fixed-temperature and rate-of-rise sensing for comprehensive heat detection. Thermal Rating: Activates at 135°F (57°C) for reliable fire response in diverse environments. Addressable Communication: Uses Velociti Series protocol for precise sensor identification and control. Rotary Dial Programming: Simplifies device addressing and setup. Compact, Low-Profile Design: Blends seamlessly into ceilings while maintaining full functionality. Ivory Housing: Aesthetic finish suited for commercial or institutional installations. Discontinued Model Support: Fully compatible with legacy Gamewell-FCI Velociti fire alarm systems. UL/NFPA Compliant: Meets fire safety standards for thermal detection performance. The ATD-RL2F delivers the reliability and precision required for addressable heat detection in both new and legacy Gamewell-FCI fire protection systems.
