Kidde | Double Action Non-Coded Conventional Fire Alarm Pull Station, 278B Series, General Alarm, Red Lexan, UL/FM Listed | GSA-M278

The Kidde 278B Series double-action pull station drops into conventional fire alarm circuits on standard 4-inch square boxes with no proprietary backbox required. Double action operation - lift the door, then pull the handle - cuts false alarms from accidental or malicious pulls, and the latching mechanism holds the alarm state until an authorized person resets it with the included key.

Built for the commercial installer

Rugged red Lexan 940 construction handles high-traffic commercial corridors, stairwells, and exit paths. UL38 (S218) and FM listed. Screw terminal connections keep field wiring straightforward, and the station mounts semi-flush on a standard 4-inch square backbox with single gang plaster cover or surface-mount with the optional 276B-RSB backbox. Break glass rod confirms intentional activation for AHJ documentation.
