The Shield photoelectric smoke detector is designed for residential and commercial residential applications, including homes, apartments, hospitals, hotels and motels, in compliance with UL217, UL1730 applicable IBC/IFC Standards and NFPA72.

Available in many different models, the detector is engineered to virtually eliminate nuisance alarms and deliver outstanding performance wherever reliable fire protection is required. The range is provided with a 9VDC alkaline battery for back-up in the event building power is lost. The battery impedance is verified and the alarm provides a low or missing battery warning.

This range of detector provides an exclusive patented three position test feature that simulates a 0.85% and 3.5% actual smoke condition in full compliance with NFPA72 and UL Standards.

Options include self-restoring 135°F integral or isolated heat thermals and Form A/Form C dry contacts for remote annunciation. Tandem interconnection of up to 12 units is available on several models; tandem interconnection of up to 6 units is available on “R” models, which activate the dry contacts from the tandem wire or a local alarm.
