RCI DOR9540-WH – Frequently Asked Questions

1) Will the RCI 9540 recessed door position switch fit a standard 3/4 inch drilled hole in a steel or wood door?
Yes. The 9540 is a 3/4 inch (19mm) diameter recessed contact, so it drops into a 3/4 inch bore, and it is self-locking in steel and wood, meaning no separate screws or clips are needed to hold it in the hole. You drill matching holes in the door edge and the frame for the switch and its magnet.
2) What voltage and current can the RCI 9540 magnetic contact switch handle?
The 9540 contact is rated 200mA maximum at 30VAC/VDC. That covers dry-contact monitoring inputs on a typical access control panel or alarm zone, but it is not a power switch, so do not run a maglock, strike, or anything else drawing real current through it. Switch a relay if you need to control a load.
3) Is the RCI 9540 door contact SPDT, and can I wire it as a normally open or normally closed loop?
SPDT, with both open and closed loop configuration supported, so you take either the normally open or the normally closed leg depending on how your panel supervises the zone. The 9540 ships with 12 inch #22 AWG leads, and end of line resistors, diodes and supervisory components are part of the series offering for supervised loops.
4) Should I use a recessed magnetic door contact or a surface mounted one for door position monitoring?
Recessed is the choice when the door and frame can be drilled and you want the contact hidden, which is what the RCI 9540 does with its 3/4 inch diameter body. Surface mount is what you use on hollow metal you cannot drill, on retrofits where you do not want to pull the door, or on overhead and roll up openings. ZenSupply carries the Schlage Electronics 7766 as a surface mount SPDT door position switch, and the Schlage Electronics 7764 as another concealed flush mount SPDT option.
5) What is the closest equivalent to the RCI 9540 recessed door position switch from another manufacturer?
The Schlage Electronics 7764 is the nearest match. It is a magnetic door position switch in a concealed flush mount configuration with a single pole double throw contact, which is the same monitoring job and the same contact arrangement as the RCI 9540 recessed magnetic contact, an SPDT switch mounted recessed into the door and frame. Both are drilled into the edge of the door and the strike face of the frame so nothing shows when the door is closed, and both give an access control panel a dry SPDT set of contacts to read door open or door closed. The 9540 uses a 3/4 inch (19mm) diameter body with a self-locking fit in steel and wood and 12 inch #22 AWG leads, so on a retrofit the deciding factor is usually whether the existing bore matches that diameter.
6) Can I use a request to exit switch instead of a magnetic door position switch?
No. They report different things and most panels want both. The RCI 9540 is a recessed magnetic contact that tells the system whether the door is physically open or closed, using a rare earth magnet and an SPDT contact. A request to exit device tells the system that someone is deliberately leaving, so the panel shunts the alarm instead of treating the opening as forced. Devices in that second group include the Command Access REXKIT-CL, a field installable request to exit switch kit for CL180 series cylindrical locks with an SPDT configuration, and the Dortronics 5286 series push plate exit release with Push to Exit text. Note that REX devices are also commonly SPDT, so matching contact configuration alone does not make one a substitute for the other.
7) The 12 inch leads on the RCI 9540 contact are short. How do I get the wire back to the panel?
You splice. The 9540 comes with 12 inch #22 AWG pigtails, which are meant to reach into the frame cavity or a hinge transfer, not to run to a panel. Plan on a junction inside the frame and a home run from there, and keep the splice accessible for service.
8) What is the difference between the RCI 9540 and the Schlage 7764 door position switch?
Both are concealed magnetic door position switches with SPDT contacts. The 9540 is a 3/4 inch diameter recessed contact that self locks in steel and wood and ships with 12 inch #22 AWG leads, rated 200mA at 30VAC/VDC. The Schlage Electronics 7764 is the flush mount concealed equivalent from another line, also single pole double throw. If your spec calls out a manufacturer by name, that is usually what decides it.
9) Is the RCI 9540 door contact strong enough to hold alignment on a warped or sagging exterior door?
The 9540 uses a rare earth magnet, which gives a longer switching gap than a standard ferrite contact, so it tolerates more gap between door and frame before it drops out. That helps on doors that shift with weather or heavy traffic. It is a commercial rated contact, which is what you want on an exterior or high cycle opening rather than a residential grade contact.
10) Can I use the RCI 9540 to monitor doors across a whole building on one access control system?
Yes, and standardizing on one contact is the point. The 9540 is a commercial door position switch with SPDT output at 200mA max, 30VAC/VDC, which suits the monitoring inputs on access control and alarm panels used in healthcare, education, government and industrial facilities. Because it supports both open and closed loop wiring with supervisory components, it drops into supervised zones as well as simple dry contact inputs, so one part number covers most of a fleet of openings that can be drilled.
11) I need a wall switch to release a door, not to monitor it. What do I order?
Order a release device rather than a door position contact. The RCI 9540 is a recessed magnetic contact that only reports door open or closed to the panel; it has no button and cannot release anything. For a person actuated release, the Locknetics CSW-100 and CSW-200 are flush mount concealed desk releases with an SPDT switch, typically mounted under a reception counter. The Locknetics WS-200 and WS-200-MB are flush mount wave switches for hands free actuation. 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 marked Push to Exit. On most monitored openings the 9540 and one of these are both installed, one on the frame and one on the wall.
12) What should I use on an exterior or wash down opening where a recessed magnetic contact is not suitable?
For the actuation device on an exposed opening, Dortronics builds sealed switches: the WR5276-HD22 series heavy duty water proof switch with a 5/8 inch round stainless entry button, and the 5277-PZL series piezo switch, a weather proof heavy duty touch sensitive push button with a dual color illuminated ring. Keep in mind these are entry and exit buttons, not position monitoring, so they answer a different half of the opening than the RCI 9540 recessed magnetic contact, which reports door open or closed through an SPDT contact and is self locking in steel and wood. On an exterior door you generally still need a position contact of some kind plus one of these sealed buttons.
13) The RCI 9540 is rated 200mA at 30VAC/VDC. What do I use if I need to switch a heavier load?
Look at a vestibule switch. The Norton Rixson 503 is an SPDT momentary push switch with a 15 amp rating, and the Norton Rixson 504 is a dual SPDT momentary vestibule switch with a stainless steel face plate. Both carry a vestibule product function, meaning they are wall or jamb mounted actuators sized for operator and higher current circuits. The RCI 9540 is a low current monitoring contact, 200mA maximum at 30VAC/VDC, intended to feed a signal into an access control or alarm input rather than to carry a load, so a heavier circuit belongs on a switch built for it while the 9540 continues to report door position.
14) What is the difference between a keyswitch and a door position switch for access control?
A keyswitch is an authorization device and a door position switch is a monitoring device. The Detex CS-400 series electronic keyswitches with LED indicators are operated by a key to command the access control system, with the LEDs giving local status feedback, and the Locknetics TS-100 is a dual LED status indicator touch switch with a programmable timer that holds a release for a set interval. Neither reports whether the door is actually standing open. The RCI 9540 recessed magnetic contact does exactly that and only that, feeding an SPDT open or closed loop signal to the panel from a 3/4 inch (19mm) contact set into the door and frame. A door held open alarm needs the position contact regardless of what commands the release.
15) What colors does the RCI 9540 recessed contact come in, and does it matter which I pick?
Two finishes, white and 693 black. It is purely cosmetic on a recessed contact since only the small 3/4 inch face shows in the door edge and frame, so match it to the door or frame color. Pick black for dark stained wood and anodized aluminum, white for painted hollow metal and light doors.
16) Is a microwave cell switch an alternative to a magnetic contact for door monitoring?
No. The Cal-Royal 8633-SW is a microwave cell switch supplied with single and double gang black faceplates; it senses motion in front of the plate to trigger a release, so it activates on a person approaching rather than on the door itself. The RCI 9540 is a magnetic contact recessed into the door and frame, and its rare earth magnet makes or breaks an SPDT contact based purely on whether the door is closed against the frame. If the panel needs to know door open or closed, a motion sensing device cannot supply that; the two are commonly installed together, the microwave cell as the egress actuator and the 9540 as the position input.
