    Safety Technology International STI-7510A-HTR – Frequently Asked Questions

    1) Will an STI heated enclosure keep a pull station or keypad working in a walk-in freezer?
    That is one of the situations these covers are built for. The STI Heated Polycarbonate Enclosures carry a built-in radiant heat plate that holds the interior above freezing, so LCDs don't go sluggish and electronics keep working in freezers, unheated warehouses, storage units, and outdoor locations. The assembly itself is rated for -40F to 250F (-40C to 121C).
    2) What voltage heater do I need to order with an STI heated polycarbonate enclosure?
    Three heater builds are offered: 12V at 19W, 16.5V at 36W, and 24V at 77W. Match it to the power you can actually run to the location. The 16.5V/36W option is the usual pick where a fire alarm or low-voltage transformer is already feeding the device, and 24V/77W gives the most heat output of the three for the coldest installs.
    3) Is this STI enclosure OK to mount outdoors in rain and washdown areas?
    Yes, it's NEMA 4X rated, which covers hosedown, wind-driven rain and corrosive conditions, so it suits exterior walls and wet interior areas. The shell is clear UV-stabilized polycarbonate, so it resists impact and won't yellow from sun exposure. Gaskets are supplied with the cover to make the seal.
    4) Can the heated STI enclosure report a cold condition back to my fire panel?
    Yes. Three thermostats are built in: a control thermostat that runs the heater, an over-temperature safety thermostat, and a low-temperature warning thermostat. The low-temp warning contact can be wired to a supervisory panel, so a facility gets notified if the interior falls off temperature instead of discovering a dead keypad on inspection day.
    5) Key lock or thumb lock on an STI heated enclosure, which should I spec?
    Both are external and both are offered across the back box choices. Take the key lock where you need to keep the public or tenants out of the device (schools, common areas, retail); take the thumb lock where only staff reach it and you want tool-free access for testing or resetting. Every combination is a clear cover except the Enclosed Back Box, which is also available in white.
    6) What is the difference between the standard and deep back box on the STI heated enclosure?
    The back box is the mounting body behind the cover, and it comes in an Enclosed Standard and an Enclosed Deep version. Pick the deep box when the device inside projects further off the wall or you need extra room behind it for wiring and the heat plate; the standard box suits flatter surface-mounted devices. There is also a plain Enclosed Back Box configuration, and that is the one offered in white as well as clear.
    7) Does an unheated protective cover work in a freezer, or do I need the heated version?
    A plain polycarbonate cover keeps dust, impact and moisture off the device but does nothing about temperature, so in a freezer or an unheated outdoor spot the LCD still slows or freezes. The heated STI enclosure adds the radiant heat plate and thermostats to hold the interior above freezing. If the device is indoors in conditioned space, the unheated cover is the simpler buy.
    8) Can I see through the STI heated enclosure to read a display or check a gauge?
    The clear polycarbonate versions let you read an LCD, gauge or indicator without opening the cover, which is why they're used over keypads and annunciators. Choose white polycarbonate instead where the device inside shouldn't be visible or you want it to blend into the wall; white is offered on the Enclosed Back Box configuration with either lock.
