Call Box

Place the alarm inside the box.

Close the lid and plug the power supply cord into the remote control switch receiver.

I used this remote control switch because I had found it to be durable and functional for a reasonable range (and through a wall or two):

Push the "on" button on the battery powered on/off switch. This will supply power to the call box and the LOUD alarm will start beeping within a few seconds.

After the alarm container has been printed, insert the wire from the 9 volt power supply through the hole in the container.

Now, solder the wires to the alarm module (where the battery was intended to connect). Be certain that polarity is correct.

I needed to make the alarm "always on" so that it would sound (and continue to sound) on power up.

First, find the "test" switch."

Next, create a solder "bridge" across the switch terminals from the back side.

Pull the electronics from a smoke detector.

I had to get somewhat physical and mangle the thing to get it out of the case.
