I have sliding metal doors which operate using push bottons (normally open 2 wire). They also operate with bumper strips (also normally open 2 wire) one on either side of the door. They open with a single press of the open push button or bumping into the vertical bumper strips down below. When the switches close they return 5 vdc back to the controller. Pretty simple. I've been asked to make a mod to prevent accidental opening. They asked for a double-click style actuation, wanting it to take two bumps of the bumper strips to open the door rather than only one. I imagine that a single accidental hit to the bumper strip would be forgotten after a couple of seconds so another accidental hit 30 seconds later would not make the door open. The double-click style bumps to the bumper strips would need to come close together.
The bumper strips are simply piggy-back connected with the open push buttons and the strips will be disconnected and only operate through the proposed mod, leaving the push buttons connected as before for single button presses to operate those.
24 vdc is readily available to power the modification, 5 vdc may also be available for use as well.
