B300-6 SYSTEM SENSOR

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.
