Camden Door Controls: Building an Accessible Opening in the Right Order

Camden Door Controls is a Canadian manufacturer of the parts that sit at the front of an assisted or automatic entry. Touchless switches, push plates and actuators, wireless transmitters and receivers, key switches, relays and timers, power supplies, and restroom control kits. What Camden does not supply is the door operator itself. That split is exactly why these openings go wrong: the pieces arrive from three vendors and nobody owns the timing between them.

KSEDCO treats an accessible opening as one sequence with one commissioning result, and we build it in a fixed order.

First, survey the approach rather than the door

Where an actuator may legally be mounted depends on the approach side, the clear floor space in front of it, and the accessibility standard the authority having jurisdiction has adopted. That is a code question we confirm with the jurisdiction instead of assuming. On a vestibule pair, the two leaves also have to be sequenced so a wheelchair user is never caught between a door that has closed and one that has not opened yet.

Second, decide wired or wireless before anything is roughed in

Camden’s Lazerpoint radio line lets an actuator sit on a glass wall, a masonry column or an existing millwork face with no conduit behind it. In a Cumberland or Perimeter tenant fit-out, that is often the difference between a fixed base-building wall staying intact and a change order. The trade is range and battery service, so we verify the radio path on site before the wall closes rather than trusting a coverage figure.

Third, choose the activation device by traffic and environment

The SureWave touchless switches offer an adjustable detection distance and clear red and green indication, which makes it a good fit for clinical corridors in Augusta, food-handling areas, and any door where hands are usually full. It is a poor fit where people walk past the switch without intending to use it, or on an exposed exterior opening in blowing rain. A plate or mushroom button is the better answer there, and we will say so.

Fourth, set the release and the operator as a single timed event

This is the step that most often ruins an opening. An operator that starts pushing before the lock has released fights the latch, and within a season it has damaged the arm, the strike, or both. The sequence has to be written down and tested as one chain: signal, unlock, confirm release, operate, hold open, close, relock. Camden relays and timers usually carry that logic, and the values belong in the closeout package, not in a technician’s memory.

Fifth, size the power for a climate that interrupts it

Summer thunderstorms drop power here often, and a low-voltage run across a large floor plate is a good antenna for a nearby strike. Surge protection at the entry, a single-point ground, and a filtered supply matter more on these circuits than the wire gauge does. If the opening has to stay usable during an outage, standby capacity is calculated from the actual operator and lock load, not carried over from another job.

Sixth, treat restroom and privacy control as its own sequence

An accessible restroom set is a small system in itself: entry activation, privacy lock, occupied indication, an emergency call device, and somewhere for that call to annunciate. In a medical building the annunciation point is the part most often left undecided until the last week. We settle it during design.

Seventh, commission the whole chain and hand over the numbers

Every timing value, radio address, relay setting and detection range is recorded, so the next person can adjust the opening without reverse engineering it. Have a door or a whole floor of them reviewed by KSEDCO on (888) 360-0035, or describe the opening here. Background reading sits on our electronic door hardware page.
