Signal and Alarms

1. Horn Signals
Application:

Horn signals are used:
  • for call signals, alarms, and various other signalling applications
  • in specific hazardous atmospheres as found in chemical plants, oil and gas refineries, bulk loading stations, paint and varnish manufacturing plants, grain processing industries and grain elevators, as well as in certain metal, coal, combustible fiber processing or handling areas.
  • in conduit systems and mounted on a flat surface with the projectors aimed in the desired direction.

2. ETH Flex Tone
Application:

Cooper Crouse-Hinds Flex-Tone Series Electronic Signals are explosionproof, heavy-duty, tone-selectable signaling devices capable of producing volume-controlled, high-decibel tones. Certified for use in Class I, Division 1, Group B, C & D applications, the Flex-Tone Series is ideal for signaling warning or emergency conditions.
Application:

Cooper Crouse-Hinds Flex-Tone Series Explosionproof Remote Speaker/Amplifier is designed for remote mounting in Division 1 areas where simultaneous high-decibel signaling is required.

3. W2H Signaling Devices
Application:

W2H series signaling devices are used:
  • as independent audible signal or warning devices.
  • in Class I, Division 2, Groups A,B,C,D hazardous areas where flammable vapors or gases may be present due to accidental or abnormal operation.
  • in Class II, Division 2, Group G hazardous areas where combustible dusts may be present due to accidental or abnormal operation.

4. ETW Telephones
Application:

ETW series telephones are used:
  • For communication in areas which may be hazardous due to the presence of flammable gases or vapors, and/or combustible dusts.
  • In chemical plants, oil refineries, bulk loading stations, paint and varnish manufacturing plants, grain processing and similar industries.

5. D2TW600 Telephone
Application:

These single-line, fully functional electronic telephones are used:
  • for communication in locations which may be hazardous due to the presence of flammable gases or vapors (Division 2), and/or combustible dusts or fibers.
  • as a single line telephone in chemical plants, oil refineries, bulk loading stations, paint and varnish manufacturing plants, grain processing and similar industries.

6. Ex-Fire Alarm Strobe Light
Application:

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
Application:

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.

8. Ex-Steady-On Beacons
Application:

Cooper Crouse-Hinds Hazard Gard EXSO and EXDSO (Diode Polarized) Series Explosionproof Steady On Beacons are designed for installation in hazardous locations where a visual signal is required for tough environmental conditions involving corrosives, water, dust and extreme temperature.

9. Ex-Rotating Beacons
Application:

Cooper Crouse-Hinds Hazard Gard EXR Series Explosionproof Rotating Beacons are designed for installation in hazardous locations, such as manufacturing plants, heavy industrial facilities, refineries, chemical, petrochemical, pharmaceutical and off-shore drilling platforms.
