Electric striker

[JJWalecka]

Question about the automatic door for ada.

If someone pushes on the actuator pads the electric strike will allow the door to be opened. Is there a bipaass of some kind that won't allow the door to open when the business is closed? How is that feature Incorporated in the wiring?

I have never seen a ADA door button tied into the striker. The door must be in the unlocked state for the ADA button to work.

FWIW, in one building I am familiar with there are panic bars on the exit doors and also an ADA push button inside and out.
When the building is locked the inside button cannot open the door unless the panic bar is also pushed. The actuator will try for ten or more seconds to open the door, allowing for moving from the push button and hitting the panic bar.
To avoid wear and tear on the actuator, the outside button is disabled by a manual switch or relay when the building is closed and the door is locked.

Thanks for the feedback. Making sense now. Seems we are missing parts

I worded it wrong.

Just to be clear, I was referring to how I have seen it done in at least two buildings. It is not a requirement, AFAIK, and I have also seen buildings where the mechanism is always activated by the outside switch and nobody cares that it hums a lot.
That particular door opener in question seems to be broken a lot, which may or may not be related.

Looking at what I was given I thought we were missing parts or not correct for this application I called tech support and they gave me information contradictive to what the door guy was saying. Tech wanted an external 24 volt transformer.... Controller had 12volt terminals. But drawing and tech support specifically wanted a separate external transformer. Door guy said to grab the power from the controller no external transformer needed

I didn't care one way or another. I just wanted it done right and move on to the next task lol

Most I have seen don't have a striker release (to open the door). When the business is open the striker is mechanically held open. If you press the button to open the door when it is locked it can't open though it does try to cycle. Not knowing anymore about these devices I have to assume it either can take the overload when the door won't open or has torque limiting devices to shut it back down if the door doesn't move or would get stuck in mid travel even. Most of them you will hear the door mechanism try to operate if you press the button when the door is "locked".
