System Sensor B300-6

Product Overview System Sensor Select Series detector bases include standard 4\" and 6\" models and specialty configurations such as relay, isolator, sounder, and low-frequency bases. Standard plug-in bases feature screw terminals for power (+/−) and remote annunciator connections, with the 4\" base compact and the 6\" base accommodating larger junction boxes.Specialty bases use a separate mounting plate compatible with multiple box sizes, allowing pre-wiring, faster installation, and a cleaner appearance.Relay bases (B224RB-WH/B224RB-IV) provide a single Form C relay for auxiliary control, including door release and elevator recall, with selectable short-delay (60–100 ms) or long-delay (6–10 s).Sounder and low-frequency bases suit new or retrofit installations, meeting UL 268/464 and NFPA 72 requirements.Key Features- Plug-in design allows fast and secure detector installation
