    Safety Technology International STI-7700 – Frequently Asked Questions

    1) What is the difference between the open back box and enclosed back box STI polycarbonate cover?
    The choice comes down to what is behind the keypad. An open back box leaves the wall opening clear, so it goes over a keypad or control that is already mounted to the wall or to an existing electrical box, and the wiring stays in the wall. An enclosed back box brings its own sealed box, so the device mounts inside the cover assembly instead of relying on what is in the wall. The enclosed versions are also the ones offered with a gasket, so if the cover is going outdoors or into a washdown or dusty area, the enclosed and gasketed build is the one to take. Both builds mount to the surface of the wall.
    2) Will an STI polycarbonate cover hold up outdoors in freezing winters and full summer sun?
    The polycarbonate covers carry an operating range of -40F to 250F (-40C to 121C), which covers any North American outdoor climate. For outdoor use, take an enclosed back box model with the gasket, since the gasket is what seals the assembly against driven rain and blowing dust. In very cold installations where the keypad itself is the concern rather than the cover, STI offers heater kits in 12-volt and 24-volt versions that go inside the enclosure.
    3) Do I need the lock version of the STI cover, or is the plain cover enough?
    Depends on who walks past it. Without the lock, the cover stops accidental impact, spray from cleaning, and casual damage, but anyone can swing it open. With the lock, the keypad or control underneath cannot be reached without a key. For tenant corridors, school hallways, gyms, pool decks, or anywhere a thermostat, volume control, or access keypad gets adjusted by people who should not be adjusting it, take the lock. Replacement keys are available as a separate accessory, which matters when a property manager is putting these on many units and needs spares in the truck.
    4) Can I still read and use the keypad with an STI polycarbonate cover over it?
    Yes. The cover is molded from clear polycarbonate, so the display and the keys stay visible through it. It is a protective shield, not a blind box. To operate the keypad you open the cover on its piano-style hinge, which runs the full length of the cover rather than using two small leaf hinges, so it takes repeated daily opening better. On a lock-equipped version, opening it requires the key, which is the point on a control you do not want the public touching.
    5) Can an STI polycarbonate cover be mounted sideways over a horizontal control panel?
    Yes, the covers mount either vertically or horizontally, so a wide horizontal keypad or a row of lighting or volume controls is handled by turning the cover on its side at install. Mounting is surface mount to the wall. Decide the orientation before you drill, since the hinge side and the swing follow whichever way you set it.
    6) What kind of controls do STI polycarbonate covers actually get used on?
    They go over wall-mounted devices that get abused or tampered with: access control keypads, card readers and control panels, thermostats, lighting controls, and volume controls. The typical jobs are a keypad in an apartment lobby, a thermostat in a classroom or hotel room that guests keep resetting, and a control panel in a garage or loading area that takes cart and equipment strikes. Clear polycarbonate means the device stays readable while shielded.
    7) Do STI polycarbonate covers come with a heater, or is that ordered separately?
    The heater is a separate item. STI offers the 6580 12-volt heater kit and the 6583 24-volt heater kit, and you match the kit to whatever low-voltage supply is already at the device. Order one of these alongside the cover for unheated exterior locations, freezer and cooler doors, or parking structures, where you are trying to keep condensation and frost off the keypad rather than just keep rain out. Match the kit voltage to the supply, not to the cover.
    8) Which STI polycarbonate cover configurations can I order?
    Five builds are offered: open back box, open back box with lock, enclosed back box, enclosed back box with lock and gasket, and that same enclosed build with lock and gasket in white. The two decisions are whether the wall opening stays open or you want the self-contained sealed box, and whether the cover locks. Note that the gasket only comes on the enclosed configurations, so an outdoor sealed installation means choosing an enclosed model.
    9) Is there a white STI polycarbonate cover instead of clear?
    Color runs clear and white. The white option comes as the enclosed back box build with lock and gasket, so if the specification calls for a white finish, you are also taking the sealed enclosed version rather than an open back. Clear is what you want anywhere the keypad face, display, or indicator lights have to stay readable with the cover closed.
    10) I have several STI covers on a property and only one key left. Can I get more keys?
    Replacement keys are offered as an accessory for the lock-equipped polycarbonate covers, so a lost or worn key does not mean replacing the cover. Worth keeping spares on hand when the same cover is deployed across multiple buildings or units and more than one technician needs access.
