Heat Detector 2500 Sq Ft

The Edwards Signaling 302-AW-135 is a rate-compensation heat detector designed for facility and traffic safety installations. It provides coverage for areas up to 2500 square feet and operates within ambient temperature limits of -40 to 100 degrees Fahrenheit. The unit meets UL and CSFM standards for reliable fire detection.

Surface Mount Installation

The detector features a surface-mount design with a depth of 2 1/16 inches and a height of 4 1/8 inches. Its compact dimensions allow straightforward mounting on ceilings or walls without recessed boxes. Incorrect spacing beyond the rated coverage area is the most common error that reduces detection reliability.

Commercial Safety Applications

This device suits building managers and contractors needing code-compliant heat detection for large open spaces such as warehouses or garages. It is not intended for residential smoke detection or for environments requiring combination smoke and heat sensing in a single unit. Buyers needing addressable loop integration should verify compatibility separately.

Questions about this item

How can I confirm the 302-AW-135 heat detector is operating correctly after surface mounting it?

After installation, apply a calibrated heat source within the -40 to 100 °F ambient range; the rate-compensation element should trigger at its fixed temperature setting, confirming the detector responds as designed.

What comes in the box with the 302-AW-135 and what must I purchase separately?

The package includes the silver/white surface-mount heat detector unit measuring 4 1/8 in high by 2 1/16 in deep; mounting hardware and any required junction boxes or wiring are not included and must be sourced separately.

Which version of the 302-AW-135 should I select for a 2 500 sq ft coverage area?

The 302-AW-135 is a single fixed-temperature model rated for exactly 2 500 sq ft; there are no alternative capacity or version options listed for this part number.
