Product Spotlight: Gentex 7139CS-C Single/Multiple Station Smoke Alarm

Gentex 7139CS-C Single/Multiple Station Smoke Alarm

Ideal for commercial residential applications, the 7139CS series from Gentex remains a popular option for those buildings requiring compliance with ANSI/UL, IBC/IFC/IRC and NFPA Standards.

These smoke alarms are photoelectric in sensing, meaning they use a light beam to detect smoke, which is deemed more effective at sounding when fire develops from a smoldering source according the NFPA.

Where both audible and visual alarms are required, the 7139CS fits the bill with it’s visual signaling appliance, designed to give early and reliable detection of smoke. Included is a 9-volt battery backup to the 120 VAC power requirement. The 7139LS version includes a 9-foot power cord, making this version completely portable.

Once activated, the 7139CS(LS) models will initiate a 90 dB audible signal along with a high intensity strobe that flashes once per second at 177 candela.

Other features include:

· Form C Relay contact for remote annunciation
· A patented 3-position test switch.
· A horn frequency of 3100Hz
· Nominal 2.5% Sensitivity
· 5:1 Signal to Noise Ratio
· Warranted for 1 year from date of purchase
