WARNINGS

The enclosure is used to protect UL Listed 1638 and 1971 visual notification appliances at temperatures down to -70F (-57C).  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 70F   (-57C) and clears the circuit at +50F (+10C).  This listing requires that the fire alarm supervisory control module be only of the latching type.  The heater assembly and gasket have a life of 5 years.  After such date a replacement heater assembly can be purchased (STI-HK2).  On the heater assembly is a label where you should record the installation date.

WARNING:  In hazardous areas all sources of power must be shutdown before accessing cover per NEC.
