RCI 903-28 – Frequently Asked Questions

1) What voltage and current does the RCI 903 audible alert need?
It runs on 10 to 26VDC and draws 30mA, so most low voltage access control supplies already on site will carry it. The wide DC range means you can share a 12V or 24V supply with maglocks or a controller without adding a separate power source. Wiring is push-on connectors, so no terminal screws to fight with.
2) Is the RCI 903 alert secure enough for a public corridor where people might pull at it?
That is what it is built for. The faceplate is extruded aluminum 1/4 inch thick with beveled edges, and it mounts with stainless steel tamper-proof screws. The spanner bit to drive them comes in the box, so the unit cannot be taken off with a standard driver.
3) Is the RCI 903 a door position switch or a request-to-exit button?
Neither. The 903 is an audible alert, a sounder that announces a condition locally or remotely. It does not sense the door and it does not release it. If you need to know whether the door is closed, use a magnetic door position switch like the Schlage Electronics 7764 concealed flush mount or the 7766 surface mount. If you need a release at the door, that is a push plate or button such as the Dortronics 5286 push plate exit release. The 903 is typically wired alongside those to give the audible.
4) Is there an RCI 903 equivalent that also handles door position monitoring instead of just sounding an alert?
No. The RCI 903 Series is an audible alert that produces a field-selectable continuous or intermittent 80-96dB tone on 10-26VDC at 30mA; it is the sounder, not the contact that senses whether the door is open. For door position sensing, the Schlage Electronics 7764 is a magnetic door position switch in a concealed flush mount with a single pole double throw contact, and the 7766 is the surface mount version of the same single pole double throw door position switch. A common pairing is a door position switch to detect the open condition and an audible alert like the 903 to annunciate it, so these are complementary rather than interchangeable.
5) I need a device at the door that lets people out, not one that makes noise. What should I order instead of the RCI 903?
The RCI 903 Series is an audible alert only - it drives an 80-96dB tone and does not switch a lock. For a release device, the Dortronics 5286 Series is a push plate exit release marked "Push to Exit", and the Dortronics 5287 Series is a heavy duty push button with a 1-1/2 inch wide push plate on a 3 inch wide back plate, also marked "Push to Exit". If you want no-touch actuation, the Locknetics WS-200 and WS-200-MB are flush mount wave switches. Many jobs use one of those to release the lock and the 903 alongside it to annunciate the opening.
6) Can the tone on the RCI 903 be changed from a steady tone to a pulsing one?
Yes, the tone is field selectable between continuous and intermittent, with output in the 80 to 96dB range. You set it during installation, so a stairwell door that needs a hard steady alarm and a stockroom door that only needs an attention pulse can both use the same part number.
7) What if there is no gang box in the wall where I need the RCI 903 alert?
Use the 9SURBOX surface-mount single gang box, an optional accessory for the 903. It lets you put the alert on a block wall, a hollow metal frame, or anywhere you cannot cut in a flush box. Order it separately; it is not included with the alert.
8) Can I use the RCI 903 alert outdoors or in a wash-down area?
The 903 is specified for commercial interior access control work and no weather or water rating is part of its build. For an exterior or wet location, look at a device made for it, such as the Dortronics 5277-PZL weather proof piezo switch or the Dortronics WR5276-HD22 heavy duty waterproof switch with a 5/8 inch round stainless button.
9) What do I need to check before wiring an RCI 903 into an existing access control panel?
Confirm the panel or power supply gives you DC between 10 and 26 volts and can spare 30mA on top of its existing load. Kill power before you land the wires, use the push-on connectors supplied, then set continuous or intermittent tone before you close the plate up. Once powered, test the audible along with whatever monitoring circuit is triggering it.
10) The RCI 903 is going on an exterior door that gets rained on. Is it rated for that, and what do you use outdoors?
The RCI 903 Series is described as a commercial audible alert with an extruded aluminum 1/4 inch plate and beveled edges for tamper resistance, but its published construction covers tamper resistance rather than weather exposure. For wet locations the Dortronics 5277-PZL is a weather proof heavy duty touch sensitive piezo push button with a dual-color illuminated ring, and the Dortronics WR5276-HD22 Series is a heavy duty waterproof switch with a 5/8 inch round stainless entry button. Both of those are actuating switches, so if you still need annunciation on that opening, keep the 903 on the protected interior side.
11) What is the difference between the RCI 903 audible alert and a keyswitch like the Detex CS-400?
They sit at different points in the access control chain. The RCI 903 Series is an output device - it takes 10-26VDC at 30mA and produces a continuous or intermittent 80-96dB tone, mounted to a single gang box or narrow stile door frame. The Detex CS-400 Series is a set of electronic keyswitches with LED indicators, meaning it is an input that a keyholder operates to arm, disarm, or release. If your panel needs both a keyed input and local annunciation, you would specify one of each rather than choosing between them.
12) Can the RCI 903 be used as a concealed release at a reception desk?
No. The RCI 903 Series is a surface device with a visible 3 inch by 4-3/4 inch anodized aluminum plate and its function is audible annunciation, not switching. For a concealed desk release, the Locknetics CSW-100 and CSW-200 are flush mount concealed desk releases with an SPDT switch. If the receptionist also needs to hear when the door is used, the 903 can be mounted at the desk alongside that release.
13) My spec calls for a timed release with a status indicator at the door. Does the RCI 903 cover that?
Not on its own. The RCI 903 Series offers a field selection between continuous and intermittent tone, but that is an audio setting, not a release timer, and it has no status LED. The Locknetics TS-100 is a touch switch with dual LED status indication and a programmable timer, which covers both the timed release and the visual status. Pair it with the 903 if the opening also needs an audible alert.
14) I need a request-to-exit signal from the lock itself plus an alarm. Does the RCI 903 provide the REX?
No. The RCI 903 Series is the audible end of that circuit and draws 30mA at 10-26VDC to sound its tone; it does not generate a request-to-exit signal. The Command Access REXKIT-CL is a field installable request to exit switch kit for CL180 Series cylindrical locks with an SPDT configuration, which puts the REX contact inside the lock chassis where the lever operates it. That SPDT output is the input side, and the 903 is what you wire in to annunciate.
15) Is a vestibule switch like the Norton Rixson 503 an alternative to the RCI 903?
They do different jobs. The Norton Rixson 503 is an SPDT momentary push switch rated 15 amps for vestibule applications, and the 504 is a dual SPDT momentary vestibule switch with a stainless steel face plate - both are actuators sized to switch power to operators. The RCI 903 Series is the annunciator, drawing 30mA at 10-26VDC to produce an 80-96dB tone, and it has no contact rating because it does not switch a load. Choose the 503 or 504 when you need to trigger something and the 903 when you need the opening to be heard.
16) What finishes does the RCI 903 audible alert come in?
Two: 628 anodized aluminum and 695 dark bronze. Both are available in the standard and the narrow stile faceplate, so you can match aluminum storefront or dark bronze frames without changing how the unit mounts.
17) Is 80 to 96dB loud enough to hear from a nurse station or back office?
At 80 to 96dB it is a local annunciator meant to be heard in the immediate area of the door, not across a building. For a remote station, wire the 903 near the person who needs to hear it, or run a second unit at that location. The device supports both remote and local monitoring applications.
18) Which of these devices resists tampering best for a public corridor?
The RCI 903 Series is built specifically for exposed locations: an extruded aluminum 1/4 inch plate with beveled edges, stainless steel tamper-proof screws, and a spanner bit included so the unit cannot be removed with common tools. Among the alternatives, the Dortronics WR5276-HD22 uses a 5/8 inch round stainless entry button in a heavy duty waterproof housing and the Norton Rixson 504 carries a stainless steel face plate, both of which are durable faces but are specified for switching rather than annunciation. For a public corridor sounder, the 903 tamper-proof screw and spanner arrangement is the relevant feature.
19) Will the RCI 903 match a black faceplate device already installed on the adjacent doors?
The RCI 903 Series is supplied in 628 anodized aluminum or 695 dark bronze, so it will match brushed aluminum or dark bronze trim but not a black plate. The Cal-Royal 8633-SW microwave cell switch is the one in the group that comes with black faceplates, in both single and double gang sizes. If the corridor is standardized on black, the 903 will read as a different finish family on that wall.
