The K-278B-1420 gives building occupants a clear, two-step activation - lift the door, then pull the handle - reducing accidental pulls while staying simple enough for the general public to operate without instruction.
Built for the commercial fire installer
Pulling the handle breaks a glass rod and trips a toggle switch, latching the handle in the alarm position until the station is deliberately reset with a key - no momentary pushbutton to second-guess. Double pole contacts give two independent switch actions per pull, and both presignal and general alarm contacts are included - authorized personnel can initiate a general alarm from any operated station using a separate general alarm key. Rugged red Lexan construction with white raised lettering stands up to daily wear in high-traffic areas.
