Safety Technology International STI-6514 – Frequently Asked Questions

1) Will an STI Bio Protector cover fit over my card reader or keypad, and how big are they?
Size decides this one. The Bio Protector measures 3.75 x 3.6 x 2.56 inches (STI-6514 clear, STI-6514-S smoke), the gasketed Bio Protector 3.75 x 3.25 x 2 inches (BIO-7504 clear, BIO-7505 smoke), and the Mini Bopper Stopper 3.75 x 3.25 x 2 inches (STI-6516). For anything larger, like a full keypad or an intercom, the Snooper Stopper runs 8.75 x 6.75 x 4.75 inches (STI-7504 clear, STI-7505 smoke). Measure your device including its trim plate and pick the cover whose interior envelope clears it.
2) What is the difference between a Bio Protector and a Snooper Stopper cover?
Different problems. A Bio Protector is the small guard, 3.75 x 3.6 x 2.56 inches on the STI-6514, sized for a fingerprint or card reader and there to stop abuse, impact, and tampering. The Snooper Stopper is the large one at 8.75 x 6.75 x 4.75 inches, and its job is shielding a keypad so nobody standing behind the user can read the code being entered. If your worry is someone shoulder-surfing an access code, you want the Snooper Stopper. If it is a reader getting hit by carts, luggage, or vandals, the Bio Protector is the right size.
3) Which STI cover is ADA compliant?
The STI-6516 Mini Bopper Stopper is the ADA compliant model in the line. It is also the one with the spring loaded hinge, so it swings open under hand pressure and returns closed on its own. If you are covering a reader on an accessible route or at an accessible entrance in a public building, that is the model to specify.
4) Can I put an STI Bio Protector or Snooper Stopper cover outside on an exterior door?
These are indoor covers. STI rates the Bio Protector and Snooper Stopper series for indoor use, so an unprotected exterior wall, a loading dock face, or a gate pedestal is outside what they are built for. The polycarbonate is UV stabilized and the material carries an operating range of -40F to 250F (-40C to 121C), which covers unconditioned indoor space like a parking garage, stairwell, or warehouse. For a genuinely weather exposed reader, look at an outdoor rated STI enclosure instead.
5) Should I order the clear or the smoke polycarbonate cover?
Clear when the device underneath has to stay readable, an LED status light, a display, or printed instructions you want people to see without opening the cover. Smoke when you want the device obscured, which is the privacy play on a keypad or a reader in a lobby where you would rather passers-by not study it. Both come in the same polycarbonate, so the choice is visibility only, not strength. Smoke is offered on the Bio Protector (STI-6514-S), the gasketed Bio Protector (BIO-7505), and the Snooper Stopper (STI-7505); the Mini Bopper Stopper STI-6516 is clear only.
6) Do I need to buy screws or a gasket separately for an STI protective cover?
No extra order needed. Mounting hardware and a gasket ship with the cover. It surface mounts, so it goes on over the device and fastens to the wall or door face rather than needing a back box or a rough-in. Plan on the fasteners suiting your wall substrate, since drywall, block, and hollow metal each take different anchors.
7) Are STI Snooper Stopper covers UL Listed for use in my facility?
The series carries UL and cUL Listing under file S7255, which is the reference your AHJ or spec reviewer will ask for on an institutional or healthcare job. The polycarbonate also carries a 94V-2 flammability rating. Those two, plus the ADA compliance on the STI-6516, are the compliance facts on record for this line.
8) I need to cover readers on 40 doors across a building. Can I standardize on one STI cover?
Usually two, not one. Reader and small keypad openings take a Bio Protector at 3.75 x 3.6 x 2.56 inches, or the gasketed version at 3.75 x 3.25 x 2 inches, and those will handle most of a card reader fleet. Larger keypads and control panels need the Snooper Stopper at 8.75 x 6.75 x 4.75 inches. Openings on an accessible route should get the STI-6516, the ADA compliant model with the spring loaded hinge. Keep one color across the building, clear or smoke, so the fleet reads as a single install.
9) What is the difference between the STI-6514 Bio Protector and the BIO-7504 with gasket?
Footprint and depth. The STI-6514 is 3.75 x 3.6 x 2.56 inches; the BIO-7504 is 3.75 x 3.25 x 2 inches, so it is narrower and shallower. Both are UV stabilized polycarbonate, both surface mount, and both ship with mounting hardware and a gasket. Pick on the envelope you need to clear over your device: if the reader projects more than about two inches off the wall, the 2.56 inch depth of the STI-6514 is the one that will close over it. Clear and smoke are available in each (STI-6514-S and BIO-7505).
10) Will a polycarbonate cover stop someone from watching a tenant punch in the door code?
That is exactly what the Snooper Stopper is for. The cover shields the keypad from view at the sides while someone enters a code, so a person standing nearby or behind cannot read the entry. Order it in smoke (STI-7505) if you want the keypad obscured when nobody is using it as well. At 8.75 x 6.75 x 4.75 inches it is sized for a full keypad rather than a bare reader.
11) What does the spring loaded hinge on the STI-6516 actually do day to day?
It returns the cover to closed on its own. A user lifts or swings it, uses the reader or control underneath, and lets go; the cover falls shut instead of being left hanging open. That matters on a high traffic opening where a propped-open guard stops protecting anything, and it is why the STI-6516 Mini Bopper Stopper is the ADA compliant model in the series, since a one motion operation is what an accessible control needs.
12) Can I use one of these covers over a light switch or a volume control, not just a card reader?
Yes, and that is a common use. The line is made to protect keypads, readers, and lighting or volume controls from theft, abuse, and damage, which is why you see them over thermostats, dimmers, and AV controls in classrooms, hotels, and common areas where you want a control present but not fiddled with. The small Bio Protector sizes suit a single gang control; the Snooper Stopper handles a larger multi gang or panel face.
