Wsdcam Freezer Fridge Door Security Alarm with Delay. Model: SF02C-WSD

This alarm has a few different options. The only option I was interested in was delayed alert for open door in refrigerator. This was purchased on Amazon in July 2020 for $13.99 and free Prime shipping. ASIN: B0784SPW44
I am only describing the delayed door alarm function. I disabled all other functions by sticking tape under the four unneeded membrane switches. That was I avoid possible confusion or malfunction if someone accidentally hit the wrong button.
Amazon reviews and description talk about delay intervals of: 5, 10, 15, 20 seconds. The item I got has delays of: 3, 15, 30, 60 seconds, which is more practical for my application. I needed a 60 sec. delay.
There are versions of this item with a remote control but no delayed alarm. This version has no remote control.
