Access Control System and Automatic Door Operator

Access Control System and Automatic Door Operator

(OP)
Hello,

I have few queries concerning the use of Access Control System and Automatic Door Operator System installed on the same door. The door in this case is an exterior door on a building which grants access to the lobby. The door has FOB type access card reader to grant access and automatic door operator with push-button on the pull side and push side for accessibility reasons. The door swing is towards the exterior of the building i.e. the pull side. The push side has free exit.

I understand that the Access Control System controls access by activating and de-activating the electric strike on the door, whereas the Automatic Door Operator System provides automatic swing of the door when a pushbutton is activated.

1. Could the Access Control System be configured to delay the re-activation of the electric strike, if the access is granted and the automatic door operator is activated via a push-button? Is 10-15 second delay for electric strike re-activation sufficient to complete the operation of the automatic door operator and back to normal condition?

2. If the Access Control System does not grant access and the electric strike is still latched, and someone activates the push-button for the automatic door operator, would the door operator attempt to open the door? Could this put undue stress on the door and the door operator, with the electric strike still latched?

3. Does the automatic door operator have necessary sensors to detect that the strike is still latched and hence would not activate the door operator?

I'd appreciate your comments to help me understand the configuration with both these systems installed.

Thank you.

RE: Access Control System and Automatic Door Operator

First off, if you're going to purchase said system get one that understands all this and be done with it.

If you have to piece this together then you should make the entire operation automatic.
On the inside triggering the opening thru a standard approach sensor when the presence of an approaching human is noted the latch is unlocked and the door automatically opens.

On the outside, when the FOB/CARD is used then the latch unlocks and the door opens outwards. Paint the ground to show the door swing area and a sign on the door "Automatic Door".

RE: Access Control System and Automatic Door Operator

A typical access control system would normally have sufficient inputs and outputs to allow for the required programming to provide door activations and inhibit signals to do what you’re looking for.
I would consult a qualified access control vendor on this though, as most areas require these systems to be permitted, and they should know if this type of interconnection would/would not violate code.
