Detex CS450 – Frequently Asked Questions

1) What cylinder does the Detex CS-400 keyswitch take, and can I key it to my existing system?
The CS-400 keyswitch accepts any standard 5, 6 or 7 pin mortise cylinder with a Yale cam, so a locksmith can key it into an existing masterkey system using the same keyway used elsewhere in the building. The cylinder is not part of the switch itself, so order one separately to match your keying.
2) Do I need a momentary or a maintained Detex CS-400 keyswitch?
Momentary is the one you want for a release or a request-to-exit pulse: turn the key, the contact closes, it springs back. Maintained holds the position until the key is turned back, which is what you use to latch a condition on, like electric dogging an exit device open for business hours or arming and disarming an exit alarm. The CS-400 comes both ways, in single and double switch versions.
3) Will a Detex CS-400 keyswitch fit in a standard single gang switch box?
It mounts in a standard switch outlet box, but the box has to be at least 1-7/8 inches deep. Shallow old-work boxes are the usual problem on a retrofit, so check the depth before you cut in. The faceplate is extruded stainless steel.
4) Do I need a keyswitch or a push button to release a door for exit?
Two different jobs. A keyswitch like the Detex CS-400 restricts who can operate it, so it's the right call for arming an exit alarm, electric dogging, or resetting a delayed egress point, where only staff should have control. If anyone leaving needs to hit it, use a push button instead: the Dortronics 5286 Series push plate carries Push to Exit text, and the Norton Rixson 503 is an SPDT momentary push switch with a 15 amp rating.
5) Can I use a Detex CS-400 keyswitch to tell whether a door is closed?
No. The CS-400 is a key-operated control input, it reports nothing about the door itself. For door position you need a magnetic position switch: the Schlage Electronics 7764 is a concealed flush mount SPDT, and the 7766 is the surface mount SPDT for doors or frames you can't drill.
6) What is the closest equivalent to a Detex CS-400 keyswitch if I need a key-operated release rather than a push button?
Among key and switch releases, the Detex CS-400 is the one built around a cylinder: it accepts any standard 5, 6 or 7 pin mortise cylinder with Yale cam, so the release is controlled by a key rather than by a button anyone can press. The Locknetics CSW-100 / CSW-200 is a flush mount concealed desk release with an SPDT switch, which puts the release under a counter where only staff can reach it instead of behind a key. If the control point must be authorized by key rather than by location, the CS-400 is the one to specify.
7) I just need a simple momentary release for a vestibule door - do I need a keyswitch?
Not if the door does not need key authorization. The Norton Rixson 503 is a vestibule switch with an SPDT momentary push switch rated 15 amps, and the Norton Rixson 504 is a dual SPDT momentary vestibule switch with a stainless steel face plate. Those are push-operated. The Detex CS-400 covers the same momentary function but through a mortise cylinder, and is offered in single and double switch configurations in both momentary and maintained versions, so it is the choice when the release must be restricted to a keyholder.
8) Is a Schlage 7764 or 7766 door position switch an alternative to a Detex CS-400?
No - they do different jobs. The Schlage Electronics 7764 is a magnetic door position switch in a concealed flush mount and the 7766 is the surface mount version, both single pole double throw; they report whether the door is open or closed. The Detex CS-400 is an operator-actuated keyswitch that sends a control input to access control, delayed egress, electric dogging and exit alarm systems. A monitored opening often needs both: a position switch to report door status and a CS-400 to authorize the release.
9) My egress side needs a labeled exit release - can I use a Detex CS-400 for that?
The CS-400 is a key-operated control, so it is not the device for a general egress push point. Dortronics offers the 5286 Series push plate exit release marked "Push to Exit" and the 5287 Series 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"; RCI's 916 Series is a tamper-resistant push button in blue with a handicap logo, 1-3/4 inch. Use one of those where any occupant must release the door, and the CS-400 on the secure side where only staff should.
10) What voltage do the LEDs on the Detex CS-400 keyswitch need?
The green and red LED indicators run on 12 or 24 VDC input, so they drop onto the same supply feeding most access control panels, delayed egress devices and magnetic locks. If you have no spare DC output to drive an indicator, order one of the no-LED versions instead: the switch contacts themselves are what the panel reads.
11) Can the Detex CS-400 be mounted so the key turns counter-clockwise?
Yes. The switch bracket has 2 positions, allowing clockwise or counter-clockwise rotation of the cylinder. That matters when the box orientation or the cylinder cam forces the key to turn the wrong way for the operator, and it means you don't have to reprep the opening to get an intuitive turn direction.
12) What is the difference between a single and a double keyswitch on the Detex CS-400?
A single switch gives you one set of contacts off one key turn. The double switch version puts two independent switches behind the one cylinder, which is what you use when a single key action has to do two things at once, say release a door and signal the alarm panel to shunt. Both are offered momentary and maintained, with or without the two LEDs.
13) What is a hands-free alternative to a Detex keyswitch for a healthcare door?
Where infection control rules out touching anything, a keyswitch is the wrong device. The RCI 913 is a microwave motion switch using doppler radar built for sterile environments, the RCI 910TC Series is a touchless actuator with a 433 MHz remote and 12/24 VDC operation, and the Locknetics WS-200 is a flush mount wave switch. The CS-400 stays the choice for the staff-only control points on the same system.
14) For an exterior or wash-down opening, is the Detex CS-400 the right switch?
The CS-400 uses an extruded stainless steel faceplate and fits a standard switch outlet box, which suits interior commercial control points. Where the device takes weather or wash-down directly, 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 piezo touch switch. Those are the ones specified for exposed locations; the CS-400 is specified where key control matters.
15) What should I use instead of a keyswitch for a hands-free release in a clean or healthcare environment?
For openings where nothing should be touched, the Locknetics WS-200 and WS-200-MB are flush mount wave switches, the RCI 913 is a microwave motion switch using Doppler radar for sterile environments, and the RCI 910TC is a touchless actuator with 433 MHz remote control operating on 12/24 VDC. The Detex CS-400 requires a key turn at the switch, which is what you want when the release must be restricted rather than automatic. Its LED indicator versions also run on 12 or 24 VDC, so it shares the power supply either way.
16) Can a request-to-exit switch in the lock replace a wall-mounted keyswitch?
They sit at different points in the system. The Command Access REXKIT-CL is a field installable request to exit switch kit for CL180 Series cylindrical locks with an SPDT configuration - it signals from inside the lock when the lever is turned. The Detex CS-400 mounts in a standard switch outlet box needing 1 7/8 inch minimum depth and is turned by key to send a remote input to access control, delayed egress, electric dogging or exit alarm equipment. A lock-mounted REX reports egress at the door; the CS-400 gives a deliberate control point away from it.
17) What is the difference between the Detex CS-400 and a microwave cell switch like the Cal-Royal 8633-SW?
The Cal-Royal 8633-SW is a microwave cell switch supplied with single and double gang black faceplates in the 8600 Series - it senses motion in front of the plate, so the door releases without contact. The Detex CS-400 is turned by a standard 5, 6 or 7 pin mortise cylinder with Yale cam and comes in single and double switch versions with momentary or maintained action. Choose the microwave cell where traffic should pass freely and the CS-400 where the release must be limited to a key.
18) What is the key switch cover option on the Detex CS-400 for?
The cover is an add-on you specify yes or no at order time. It sits over the keyswitch to keep casual users out of it, which is the usual choice in a corridor, a lobby, or a school where the switch is in public reach. Every switch configuration, single or double, momentary or maintained, LED or not, can be ordered with or without it.
19) Can I standardize one Detex CS-400 model across every door in the building?
You can standardize the faceplate and the cylinder, and that's usually the win: same 5, 6 or 7 pin mortise cylinder with Yale cam on every point, so one key runs the building. The switch itself should follow the function of each opening, momentary where it's a release and maintained where it holds a condition, and you only pay for LEDs at the points where staff needs to see status.
20) Will an RCI 903 audible alert do the same job as a Detex CS-400 keyswitch?
No. The RCI 903 Series is an audible alert with a tamper-resistant design rated 80 to 96 dB - it announces a condition, it does not switch a circuit for you. The Detex CS-400 is the input device, sending remote control signals to exit alarms and delayed egress hardware, with green and red LED versions to show the state at the switch. On an alarmed opening the two are complementary: the CS-400 arms or bypasses, the 903 sounds.
