RCI 918-TD 28 – Frequently Asked Questions

1) Will the RCI 918 exit button fit a narrow stile aluminum door frame?
Yes. The 918 comes in a narrow faceplate measuring 1-5/8"W x 4-3/4"H made for narrow-stile door frames, alongside the standard 3"W x 4-3/4"H plate that drops onto a single gang box. Pick the narrow plate for storefront and aluminum stile frames, the standard plate for a wall box beside the opening.
2) Momentary, maintained, or time delay - which RCI 918 switch mode do I need for my door?
Momentary (2-SPST) breaks the circuit only while the button is held, which is what you want for a normal request-to-exit on a maglock or electric strike. Maintained (2-SPST) latches the state until the button is pushed again, so it works where you need the door held unlocked, like a receptionist unlocking a lobby for a period. Electronic time delay (DPDT) releases and then re-secures on its own after the delay expires. All three are ordered as the same 918 button, just a different switch mode.
3) Is the RCI 918 push button vandal resistant enough for a school or public corridor?
It's built for that. The faceplate is extruded aluminum 1/4" (6.4mm) thick with beveled edges, and it ships with stainless steel tamper-proof screws plus the spanner bit to drive them, so the plate can't be pulled off with a common screwdriver. The actuator is a 1-3/4" (44mm) mushroom head. It's a commercial-rated device, not a residential one.
4) Do I need anything besides the RCI 918 button to finish the install?
The button ships with its tamper-proof stainless screws and the spanner bit. What you supply is the box and the wire: a standard single gang box for the 3" plate, or the 9SURBOX surface-mount box if you're going on a surface where you can't cut in. If you want a timed release without ordering the time delay switch mode, RCI offers the TD30 fixed 30-second timer or the TD30A adjustable 0 to 30 second timer, both 12/24VDC.
5) Can the RCI 918 exit button be mounted outdoors or in a wash-down area?
No. The 918 is an interior commercial device, aluminum plate with a mushroom button, and nothing in its build addresses weather or water. For an exterior gate, a loading dock, or anywhere it gets hosed, go to a sealed switch instead: the Dortronics WR5276-HD22 Series is a heavy duty waterproof switch with a 5/8" round stainless entry button, and the 5277-PZL piezo is a weatherproof heavy duty touch button.
6) I need request-to-exit signalling from the lock itself, not a wall button. Is the RCI 918 the right part?
No. The 918 is a wall or frame mounted button the person actually presses. If you need the REX signal generated by the lever being turned inside the lock, that's a switch kit in the lockset, such as the Command Access REXKIT-CL field installable request to exit switch kit for CL180 Series cylindrical locks, SPDT. And if what you actually need is to know whether the door is open or closed, that's a door position switch like the Schlage Electronics 7764 concealed flush mount or the 7766 surface mount, both SPDT.
7) What can I use instead of the RCI 918 exit button on an exterior door that gets rained on?
The RCI 918 is a commercial exit switch with an extruded aluminum 1/4 inch plate and 1-3/4 inch mushroom push button, built for interior mounting to a single gang box or narrow stile frame. For an opening exposed to weather, the Dortronics WR5276-HD22 is a heavy duty water proof switch with a 5/8 inch round stainless entry button, and the Dortronics 5277-PZL is a weather proof heavy duty touch sensitive piezo push button with a dual-color illuminated ring. Both are built as weather-rated devices, where the 918 is specified for commercial interior access control use.
8) Is there a no-touch exit device I can use instead of a push button for an infection control area?
The RCI 918 is a mechanical push button - a 1-3/4 inch mushroom button the user presses. If the requirement is hands-free release, the Locknetics WS-200 and WS-200-MB are flush mount wave switches, and the Locknetics TS-100 is a touch switch with dual LED status indicators and a programmable timer. The 918 covers the same request-to-exit role with a physical button and is offered in momentary, maintained, or electronic time delay switch modes.
9) I need a door position switch - will an RCI 918 work for that?
No. The RCI 918 is a manually operated exit push button that a person presses to release the door; it does not report whether the door is open or closed. For door position monitoring, the Schlage Electronics 7764 is a concealed flush mount magnetic door position switch with a single pole double throw contact, and the Schlage Electronics 7766 is the surface mount version of the same magnetic door position switch, also single pole double throw. Those two sense the door; the 918 releases it.
10) I need two separate circuits switched from one exit device - what are my options?
The RCI 918 in electronic time delay form uses a DPDT switch, while its momentary and maintained forms use 2-SPST. For a comparable two-circuit device, the Norton Rixson 504 is a dual SPDT momentary vestibule switch with a stainless steel face plate. Single-circuit alternatives include the Norton Rixson 503, an SPDT momentary push switch with a 15 amp rating, and the Command Access REXKIT-CL, which is SPDT.
11) What finishes does the RCI 918 exit button come in, and will they match my other door hardware?
Two faceplate finishes: 628 anodized aluminum (brushed clear) and 695 dark bronze (brushed anodized). Both are available across every switch mode and in both the standard and narrow plate sizes, so a building standardizing on bronze can keep the finish consistent whether the button lands on a wall box or a storefront stile.
12) Should I use a mechanical push button like the RCI 918 or a touchless wave switch for exit release?
A mechanical mushroom button is the straightforward choice where you want positive tactile feedback and a device that can't be false-triggered by someone walking past. The 918 adds a 1/4" extruded aluminum plate and tamper-proof fasteners for locations that get abused. If the application is a healthcare corridor or anywhere hands-free matters, look at a touchless option instead, such as the Locknetics WS-200 flush mount wave switch or the Dortronics 5277-PZL piezo touch button with its illuminated ring.
13) What can I use instead of an RCI 918 if I need a large push plate rather than a small button?
For a bigger target that someone can hit with an elbow or a cart, the Dortronics 5286 Series push plate exit release with "Push to Exit" text is the plate-style alternative, and the Dortronics 5287 Series gives a 1-1/2" wide push plate on a 3" wide back plate. The 918 is the opposite approach: a 1-3/4" mushroom button on a tamper-resistant aluminum plate, better where you want a deliberate press and a vandal-resistant face.
14) Does the RCI 918 need two separate circuits, like a maglock plus an alarm shunt?
The momentary and maintained versions are 2-SPST, meaning two independent single-pole contacts, so you can break the maglock circuit on one and shunt an alarm or signal the access panel on the other. The electronic time delay version is DPDT, giving you two changeover contacts with both normally open and normally closed available. Match the mode to how many circuits your panel needs.
15) What should I use if I want the exit release hidden rather than a visible button on the wall?
The RCI 918 is a visible wall device with a red faceplate carrying EXIT text and a 1-3/4 inch mushroom button, mounted to a single gang box or narrow stile frame. Where the release needs to be out of sight, the Locknetics CSW-100 and CSW-200 are flush mount concealed desk releases with an SPDT switch, intended to be mounted under a reception desk rather than on the door wall. The 918 puts the release at the opening where any occupant can find it.
16) What is the difference between an RCI 918 exit button and a keyswitch like the Detex CS-400?
The Detex CS-400 Series are electronic keyswitches with LED indicators for access control systems, so operation requires a key held by authorized staff. The RCI 918 is a push button anyone can press, with a red faceplate and EXIT text, offered in momentary, maintained, or electronic time delay switch modes. Use the keyswitch where you want operation restricted to keyholders and the 918 where the release is for general egress.
17) Is a microwave sensor or a push button the better choice for an automatic door vestibule?
The Cal-Royal 8633-SW is a microwave cell switch supplied with single and double gang black faceplates, so it triggers on motion with no contact. The Norton Rixson 503 is an SPDT momentary push switch rated 15 amps for vestibule use, and the Norton Rixson 504 is a dual SPDT momentary vestibule switch with a stainless steel face plate. The RCI 918 sits with the push switches - it is a deliberate press on a 1-3/4 inch mushroom button, with tamper-proof stainless screws and a spanner bit in the kit, which is what distinguishes it where the device is reachable by the public.
18) Can I replace a Norton Rixson vestibule switch with an RCI 918?
Not as a drop-in. The Norton Rixson 503 is an SPDT momentary vestibule switch rated 15 amps and the 504 is a dual SPDT momentary with a stainless face plate, and neither shares the 918's plate dimensions or contact arrangement. The 918 standard plate covers a single gang box at 3"W x 4-3/4"H, so treat it as a new install and verify the box and the contact configuration your panel expects.
