Available in many different models, the 9120/9123 Series is engineered to virtually eliminate nuisance alarms and deliver outstanding performance wherever reliable fire protection is required. The 9000/9003 Series is provided with a 9 VDC alkaline battery for backup in the event building power is lost. The battery impedance is verified and the detector provides a low or missing battery warning.
The Gentex 9000/9003 Series provides an exclusive patented three position test feature that simulates a 0.85% and 3.5% actual smoke condition in full compliance with NFPA 72 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 “F” models, which activate the dry contacts from a remote alarm through the tandem wire or a local alarm.
The 9003 Series provides the temporal 3 evacuation tone as a standard feature. When testing the 9123 Series it may take up to 16 seconds longer to go in or out of alarm.
