6. Ex-Fire Alarm Strobe Light
The EXFASC Series Fire Alarm Explosionproof Strobe contains a supervisory diode for use
in fire alarm applications. Under normal operation the diode is reversed biased, meaning it
blocks voltage from being applied to the strobe light and prevents it from lighting. When a
fire-initiating device such as a smoke alarm is activated, the diode’s polarity is reversed through
a fire alarm panel. The diode becomes forward biased, allowing voltage to the device and
activating the strobe.
7. Ex-Strobe Light
Cooper Crouse-Hinds Hazard Gard EXS and EXDS Series Explosionproof Strobe Lights are
designed for installation indoors and outdoors in locations which are hazardous due to the
presence of flammable vapors or gases, ignitible dusts or ignitible fibers and flyings. The units
are UL listed for Type 3R and 4X installations. The 120V and 24VDC models are Marine Rated.
The strobes are available for pendant, wall, stanchion and ceiling mounts, and come in six
different globe colors.
