Camden Door Controls CM-7536/4 BRZ – Frequently Asked Questions
1) Will the Camden CM-74/75 push plate work if there's a header or transom right above where I'm mounting it?
Yes. The 'Top Load' Column push plates are built for openings with no clearance above the unit. The wire enters from the top of the plate rather than requiring space overhead for a conventional load, and the assembly sits only 1-1/2 inches deep on the wall surface. If you have room above and don't need the low profile, a standard column plate is the simpler pick.
2) Do I need to cut in a back box for a Camden 36 inch column push plate switch?
No back box. The CM-74/75 column plates surface mount and come with leveling screws, so they go on finished wall, block, or a mullion face without any wall opening. That makes them the practical choice on retrofits where you're adding an operator to an existing lobby and don't want to open the wall. The plate stands 1-1/2 inches off the surface once mounted.
3) What's the difference between the Camden CM-74 and the CM-75?
Width, and nothing else in the core spec. The CM-74 column is 4.5 inches wide and the CM-75 is 6 inches wide. Both run 36 inches tall. Pick the 6 inch face where you want a larger target for wheelchair and cart users or a bigger graphic, and the 4.5 inch where you're fitting a narrow return, a mullion, or a tight jamb wall.
4) Can I wire a Camden column push plate directly to a low voltage door operator input?
Yes. The standard CM-74/75 plates are a dry contact switch, SPDT momentary Form C, rated 15 amps at 30 VDC, so they land on the actuator input of an operator or access control panel with no power to the plate itself. If you order a VR (voice/annunciator) model instead, that one needs 12-24 VDC at plus or minus 10 percent and its contacts drop to 1 amp at 30 VDC. Check which one you're specifying before you size the supply.
5) Are Camden column push plates approved for use on a Canadian project?
The CM-74/75 columns are OBC, NBC, and CSA compliant, which covers Ontario and national code work in Canada. One exception matters on the order form: the stainless steel model is not CSA compliant. If the job is in Canada, stay with the aluminum plate.
6) How much current does a Camden CM-74/75 powered column plate draw?
40 mA. That's small enough that a handful of plates on one 12-24 VDC supply won't move the needle on a typical operator's auxiliary output, which matters when you're feeding both sides of a vestibule plus an interior plate off one transformer.
7) Is there a Camden 36 inch push plate that doesn't have to be touched?
Yes, a built-in touchless activation sensor is available as an option on the CM-74/75 column plates. That's the version to spec for healthcare, food service, or any facility that has moved to hands-free entry. The same column also has options for Kinetic or Lazerpoint wireless, which lets you activate an operator without pulling wire back to it.
8) Which graphic should I order on a Camden accessible entrance push plate?
Four faceplate graphics are offered on both the 4.5 inch and 6 inch columns: the wheelchair symbol alone, wheelchair with 'PUSH TO OPEN', wheelchair with 'PUSH TO OPEN' plus a foot icon, and the 'ACTIVE WHEELCHAIR' symbol with 'Push to Open'. The foot icon version is the one to use where you expect users with full hands, since it tells them they can activate with a foot. Some jurisdictions and campus standards call for the active wheelchair symbol, so match whatever is already on your other openings.
9) Is a 36 inch column push plate better than a round or square wall button for an accessible entrance?
A 36 inch column gives you a continuous activation strip instead of a single point, so a user in a chair, on a scooter, or pushing a cart can hit it anywhere along its height without lining up on a small button. That's why they get specified in hospitals, schools, and multi-family lobbies where traffic varies. A conventional 4-1/2 or 6 inch square plate is fine when the users are consistent and you have a clean mounting height. Where the column wins is variable user height and glove or elbow activation.
10) What finishes do the Camden CM-74/75 columns come in, and will they hold up outdoors?
Three: clear aluminum, dark bronze anodized aluminum, and blue. All three are available on both the 4.5 inch and 6 inch widths and on every graphic. The plate substrate is aluminum, and the dark bronze is anodized, which is the one that tends to get specified on exterior storefront and entry vestibules to match bronze framing. Blue is the high-visibility choice institutional buyers use to make the accessible entrance obvious across a lobby.
