The Kidde Commercial K-278B-1120 is a non-coded double-action manual pull station for commercial fire alarm systems. Specifically, it features a Lexan housing with single-pole (SPST) screw-terminal contacts and key reset.
In addition, double-action operation requires a deliberate lift-and-pull sequence. As a result, accidental activation in high-traffic locations drops significantly.

First, the user lifts the front cover. Then, the user pulls the handle down to latch the open-circuit alarm contact. Finally, an authorized technician resets the station with a key.
Furthermore, the K-278B series uses screw-terminal field connections. By contrast, the related K-279B series uses 6-inch wire pigtail leads. Therefore, choose the variant that matches your wiring practice.
Compatibility
The K-278B-1120 is non-coded. As a result, it suits standard initiating device circuits without coded-pulse requirements.
