SHIELD Photo-Electric Smoke Detector works on the light-scatter principle
and is ideal for applications where slow-burning or smoldering fires are likely.
SHIELD Heat Detector is distinguishable by the low airflow resistant case and
uses a single thermistor to sense the air temperature around the detector.
■ Responds well to slow-burning, smoldering fires.
■ Well suited for bedrooms and escape routes.
■ Unaffected by atmospheric pressure.
■ Ideal for environments that are dirty or smoky under normal conditions.
■ Well suited for warehouses, loading docks and parking garages.
■ Unaffected by wind or atmospheric pressure.
■ Remote test feature.
