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

E-Controls.net now includes Inovonics® line of UL 864 certified commercial fire alarm system devices.

Inovonics® has designed a way to easily integrate their commercial fire devices into fire alarm systems.

Using Inovonics® RF gateways, these wireless devices are able to be added to most commercial fire alarm systems.  The EH4104R (datasheet) Receiver with Relays was designed to be used with the EchoStream® EH1115EOL (datasheet) Single Input Fire RF Transmitter (2.21K ohm end-of-line resistor, included and required for operation).  Together, these units monitor water flow and pressure in piping and post indicator valves, to deliver an alert upon the activation of a fire protection system.

As the integrating device, the EN4104R add-on receiver acts as an input to the commercial fire alarm system using hardwired form C relays.  Sending wireless signals to this receiver is the EH1115EOL single input RF transmitter, normally located in the Fire Pump Room.

Inovonics® wireless transmitters have covered government facilities, historic and national landmarks, schools, banks, hospitals, and other critical infrastructure facilities, making their fire systems tailor-made for commercial buildings of any kind.
