Kidde FX-278 Double-Action Intelligent Addressable Fire Alarm Pull Station

The Edwards FX-278 is an intelligent addressable double-action manual pull station designed for use in life-safety fire alarm systems. Requiring an occupant to lift the handle and pull in two distinct motions, the double-action mechanism significantly reduces the risk of accidental activation in high-traffic commercial, institutional, and industrial environments. The FX-278 communicates over an addressable signaling line circuit, reporting its unique device address directly to a compatible Edwards fire alarm control panel. Its red Lexan 940 housing with white lettering is immediately recognizable as a fire alarm initiating device, and the station accommodates standard North American electrical boxes for straightforward retrofit or new-construction installation.

Key features & benefits

• Intelligent Addressable Communication — Operates on an addressable signaling line circuit at up to 20V peak-to-peak, allowing the control panel to pinpoint the exact activated station and accelerating emergency response.
• Double-Action Activation — Requires a deliberate two-step operation—lift then pull—to trigger an alarm, drastically reducing nuisance activations in schools, hospitals, and public facilities.
• Ultra-Low Standby Current — Draws only 350 microAmps in standby, minimizing loop power consumption and supporting longer signaling line circuit runs with more devices.
• Wide Device Addressing Range — Field-configurable device address from 01–64 on 64-point control panels, or 01–127 on 127-point control panels, providing flexible system design.
• Broad Environmental Tolerance — Rated for operation from 32°F to 120°F (0°C to 49°C) and 0–93% RH non-condensing, suitable for a wide range of commercial and light-industrial environments.
• Universal Box Compatibility — Mounts directly to a standard North American 2½ in. (64 mm) deep 1-gang box, or a 4 in. square box with 1½ in. (38 mm) deep 1-gang cover, supporting flush or surface installation without special adapters.
• Flexible Wiring Options — Accepts 12, 14, 16, or 18 AWG wire (0.75–2.5 mm²), with 16 and 18 AWG preferred, easing installation in new and existing conduit systems.
• Agency Approvals — UL Listed, ULC Listed, and CSFM Listed, meeting the certification requirements for fire alarm initiating devices across the United States and Canada.
