Automatic Door Operators

The common causes are, in order: the operator has been switched off or is in hold-closed mode, the activation device (push plate, sensor or access reader) has failed or lost power, the safety sensors see an obstruction such as snow or a sign, or the operator has faulted after meeting too much resistance. A technician can identify which within minutes.

Usually a sensor is seeing something it should not: a plant, a mat edge, blowing snow, sun glare or a reflective floor. Less often the closing force is set high enough that the door meets resistance and reverses for safety. Both are adjustments rather than repairs.

The opening limit or speed has drifted, the door is meeting resistance from a stiff closer or ice, or the floor stop has been moved. Low-energy operators are designed to stop if they meet an obstruction, so a door that stops partway is protecting someone rather than failing.

In most cases, yes. A low-energy operator fits on the header of many existing hollow metal, wood and aluminum doors, and works with your current closer, lock and access control. We check the door weight, frame condition and clearances during the site visit.

It is an operator that opens the door slowly and with limited force, so it is safe to use without the overhead safety sensors a full-energy door needs. Low-energy operators are activated by a push plate or access reader and are the standard choice for accessible entrances at offices, clinics and washrooms.

Have a daily walk-past by your own staff to confirm the door opens, closes and reverses, and a professional inspection at least annually, or seasonally in Saskatchewan where cold weather changes how the door and closer behave. Manufacturers and the applicable standards expect regular documented inspection.

Yes. The operator is simply told to open once the access system has released the electric strike or mag lock. Sequencing the two correctly matters, and we install both so they are set up as one system.
