Stopper ^® Dome Heated Enclosure for Strobe Only NEMA 4X Hazardous Locations
STI-1229HTR-HAZ

Environmental enclosures with 110 VAC heater for signaling appliance unit UL, cUL and Hazardous Listed to NEMA 4X Standards

Now there is a way to protect your signaling device located where temperature or environmental conditions exceed the suggested operating range of your strobe. Thermostatically controlled 110 VAC heater and a continuous duty fan maintain a uniform temperature in the cover when located in a cold environment. Applications include, but are not limited to, refrigerators, freezers, meat packaging plants, arctic environments, ocean rigs, slaughter houses, etc. UL Listed down to -70 °F (-57 °C) and NEMA 4X Rated.

STI-1229HTR-HAZ FEATURES

• Maintains operating strobe appliance temperature with external temperatures to -70 °F (-57 °C).
• Enclosure temperature is maintained between 50 °F and 70 °F (10 °C and 21 °C) to prevent external moisture condensation from forming.
• For use in areas where temperature or environmental conditions exceed the operating range of fire strobe signaling devices.
• Protects ADA Compliant strobes to UL 1971 Standards.
• The thick, clear polycarbonate cover is UV-stabilized.
• Rated for indoor and outdoor applications.
• Enables ADA Compliance for visual fire protection systems where freezing temperatures or other harsh conditions exceed the operating limits of strobe signal devices.
• NEMA 4X Rated. Dust tight (Class II Group F and G Div. 2). All Class III locations.
• 110 VAC heater assembly rated to -70 °F (-57 °C).
• Prevents build up of snow on the unit or entry of moisture in wash-down areas to assure that strobes remain clearly visible.
• Fan runs continuously to maintain a uniform temperature inside the enclosure.
• Heater units cycle as required to maintain the correct range of operating temperatures.
• Typical working properties of polycarbonate are -40 ° to 250 °F (-40 ° to 121 °C).
• Lifetime guarantee against breakage of polycarbonate in normal use (one year on electro mechanical and electronic components).
• cUL Listing is for UL 1638 strobes only.
• CSFM requires local approval only.
• Enclosed backbox.
• Includes double gang appliance plate which eliminates the need for an electrical outlet box

Important Note:

The enclosure is used to protect UL Listed 1638 and 1971 visual notification appliances at temperatures down to -70 °F (-57 °C). It is the installer's responsibility to comply with NFPA 72, NEC, and other applicable fire and electrical codes. Conduit or raceway paths need to be sealed as near to the enclosure as possible. Installer should have maintained supervision over the low temperature thermostat. The low temperature monitoring thermostat makes the circuit at +32 °F (0 °C) and clears the circuit at +50 °F (+10 °C). This listing requires that the fire alarm supervisory control module be only of the latching type. The heater assembly, fan and gaskets have a life of 5 years; after such date a field replacement kit can be purchased. On the heater assembly is a label where you should record the serial number and the installa
