Kidde - Edwards K-278B-1120 Break Glass Pull Station

Product Description

The KIDDE - EDWARDS K-278B-1120 is a single-action, break-glass pull station designed for use in fire alarm systems. When activated, the user breaks the glass element to trigger the alarm circuit, providing a clear, tamper-evident indication of manual activation. The terminal-style wiring connections allow for straightforward integration into conventional fire alarm control panel circuits. This pull station is installed by licensed fire alarm technicians and low-voltage electricians in commercial and institutional buildings requiring code-compliant manual initiation devices.

The K-278B-1120 is suited for manual fire alarm initiation in commercial, institutional, and light industrial environments. It is typically mounted at exit points, corridors, and stairwells in accordance with NFPA 72 requirements for manual pull station placement. The break-glass design provides a visual tamper indicator, making post-event inspection straightforward for AHJ review and system reset procedures.
