Safety Technology International STI-3353-PARTS – Frequently Asked Questions
1) How far can the STI-3353 chime receiver be from the transmitter?
The STI-3353 wireless chime receiver works at up to 500 feet from the transmitter. That is a line-of-sight style rating, so walls, metal doors and distribution racks in a warehouse or clinic will cut into it. If the run between your entry door and the office where staff need to hear the chime is longer than that, put the receiver closer to the transmitter rather than closer to the staff.
2) Does the STI-3353 receiver need hardwiring or a battery?
Neither. The receiver plugs into any standard 120 VAC outlet, so there is no wiring, no transformer and no low voltage run to pull. That makes it a tenant-friendly install for a leased suite or a rented storefront where you cannot open walls.
3) Can one STI-3353 chime receiver cover several doors or call points?
Yes. A single STI-3353 receiver accepts up to 10 transmitters, so one plug-in unit can cover a front entry, a back door, a loading dock and a service window at the same time. With 10 selectable chimes you can assign a distinct tone to different transmitters so the person at the desk knows which point was triggered.
4) Is the STI-3353 a complete doorbell kit or just the receiver?
It is the receiver only. The STI-3353 is the plug-in chime unit from Safety Technology International's Musical Wireless Chime series; you still need at least one compatible transmitter (push button, door contact or other call point) to trigger it. Order the transmitter separately, and remember the receiver will pair with as many as 10 of them.
5) Is the STI-3353 chime loud enough for a noisy shop floor?
Output runs 64 dB to 88 dB measured at 1 foot, and the receiver has a low and high volume adjustment. At 88 dB on high it carries in a busy office or retail space. On a genuinely loud shop floor with machinery running, treat it as a supplement, not a primary alert, and position the receiver near the person who has to respond.
6) Is the STI-3353 receiver UL Listed?
The STI-3353 wireless chime receiver is UL and cUL Listed, which covers it for both US and Canadian installations. That matters for facility and institutional buyers who need listed equipment on plug-in devices in occupied buildings.
7) Can I add more chime receivers so staff in different rooms all hear the alert?
Yes, and that is the usual way to cover a larger footprint. Each STI-3353 is an independent plug-in unit, so you can put one at the front desk, one in the back office and one in a stockroom, all triggered by the same transmitters within the 500 foot range. Set the volume switch per location so the quiet office is not running at 88 dB.
8) Can the STI-3353 be mounted outdoors or in an unheated area?
No. It is a 120 VAC plug-in interior chime receiver, so it belongs on a standard indoor outlet in conditioned space. For an exterior call point, the transmitter side is what goes outside, not this receiver.
