The System Sensor RTS151KEY is a professional-grade remote test station with key specifically engineered for duct smoke detector testing and monitoring in commercial HVACR environments. Designed to provide a centralized access point, this station allows technicians to initiate a functional duct detector remote test and smoke detector reset without needing direct physical access to units mounted in high ceilings or confined ductwork. It operates on a versatile 2.8 to 32Vdc power supply for the alarm LED, while the standby green LED utilizes a 14 to 35Vdc range, ensuring compatibility across a wide variety of fire alarm system accessories. This model is the direct replacement for 70-200000-912 and the RA-912 legacy stations. Utilizing a secure, key-activated switch to prevent unauthorized tampering, the station provides clear visual feedback via a multi-colored LED: steady green confirms board presence and power, while red indicates an active alarm state with a maximum 40-second response time. It is a critical component for maintaining NFPA 90A compliance in complex air handling systems. Key Benefits for HVACR Contractors: Simplified Maintenance: Facilitates rapid duct smoke detector testing and resetting from floor level, reducing labor time and the need for ladders or lifts. Secure Access: The key-operated design prevents unauthorized resets, maintaining the integrity of the fire safety system. Universal Compatibility: Works seamlessly with InnovairFlex duct detectors and serves as a verified replacement for RA-912 and 70-200000-912 units. Diagnostic Feedback: Integrated multi-colored LED station indicators provide immediate status verification for both alarm and power conditions. Robust Construction: Built for commercial duty with a temperature range of 14°F to 140°F and fits standard single-gang electrical boxes for easy installation. Common Questions: What is the maximum distance I can install the RTS151KEY from the detector? For standard applications, the distance is typically determined by the voltage drop across the 14 to 18 AWG field wiring; however, in Canadian installations, it should be located in the same room and within 60 feet of the unit. Does this unit require a separate test coil? A test coil (DCOIL) is required only when using the RTS151KEY with certain legacy models like the D2, DNR, or DH400/500 series. Modern InnovairFlex models generally do not require the separate coil for remote testing. Can I use this for both 2-wire and 4-wire systems? Yes, the RTS151KEY is compatible with both. For 4-wire detectors, the LED alternates between green and red, while in 2-wire configurations, the LED serves as a red alarm indicator.
