The K-278B-2320 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. Presignal alarm contacts let authorized personnel initiate a general alarm from any operated station using a separate general alarm key, a common requirement in phased-evacuation buildings. Rugged red Lexan construction with white raised lettering stands up to daily wear in high-traffic areas.

FAQs

How does presignal operation work?
The initial pull activates a presignal (alert) condition; authorized personnel can then initiate a general alarm from any operated station using a separate 276-K2 general alarm key.
What's needed to reset the station after activation?
The 276-K1 reset key (included), used to open the station, restore the toggle switch, and replace the glass rod.
Is the surface back box included?
No. For surface mounting, order a 276B-RSB back box separately. Semi-flush mounting uses a standard 4-inch square box with plaster cover.
