The Gentex 9120F is a 120VAC photoelectric smoke detector with a continuous 90dBa piezo sounder and A/C contacts.

Like other models in Gentex's 9000/9003 series, the 9120F offers an exclusive three-position, self-testing feature that can simulate 0.85 or 3.5 percent actual smoke conditions, in compliance with UL and NFPA standards. The 9120 can also be wired to work in tandem with up to 6 other Gentex tandem-capable devices for more comprehensive alarm system coverage.

Other features include pulsing LED lights for easy visual status notification and a 9VDC backup battery to ensure device functionality in power outage situations. The 9120F can be mounted on any standard junction box, with included dust cover, insect screens, and EasyWash maintenance for simple system upkeep.
