The System Sensor RA100Z is a high-performance remote annunciator engineered for seamless integration across both conventional and intelligent fire systems. Trusted by veteran HVACR technicians, this polarized accessory features a built-in active current regulator that limits draw to a primary 10 mA maximum current while ensuring stable operation across a broad 3.1 to 32Vdc voltage range. Designed for field durability, the RA100Z remote LED provides a high-visibility alarm status indication, making it essential for monitoring duct smoke detectors and other concealed fire safety components installed in commercial mechanical rooms. Whether you are wiring a legacy 2-wire setup or a modern addressable loop, this unit provides the precise visual alarm indication required to meet strict life safety codes and simplify troubleshooting for the service contractor. Key Benefits for Technicians: Universal Compatibility: Operates efficiently across conventional systems and intelligent addressable loops. Low Power Draw: Sophisticated active current regulation keeps system load at a minimum, allowing more devices per circuit. Standardized Installation: Mounts directly to a standard single-gang electrical box, ensuring a clean and professional field finish. Flexible Input Support: Reliable operation within a 3.1 to 32 VDC window allows for diverse application in various low-voltage fire alarm infrastructures. Common Questions: Is a jumper required for the System Sensor RA100Z? Yes, for conventional fire alarm applications, the on-board jumper must be installed to operate within the 3.1 to 32 VDC range. For intelligent systems, the jumper is typically omitted to align with 18 to 32 VDC requirements. How many wires are required for field installation? The RA100Z annunciator is a two-wire polarized device. Proper polarity must be observed during termination to the monitored detector or control panel terminals. Where is the System Sensor RA100Z primarily used? It is the standard choice for providing remote alarm visibility for InnovairFlex duct smoke detectors and other sensors located in hard-to-reach areas like ceiling plenums or air handlers.
