Window switch wired to HR92

Hi
I was minded to fit a window contact HCA30 to my bathroom window so as to ensure the heat in the room is off when the window is open. I would need cable ACS90 as well. This sounds easy. However, after registering on the Resideo website and attempting to purchase the HCA30 window contact, I discover they do not supply this any more! Well done, Resideo! I wondered whether they have abandoned this feature.
I thought I would buy elsewhere. I discovered that is not easy. The best option - a foreign supplier - involved pricy items plus postage costs making me think twice about the project.
I can purchase a cable cheaply from a number of sources - and further choose whatever length I need. (mini usb at one end, chop an unused fitting off the other end if appropriate.) A substitute for the window contact HCA30 is more problematic. There are lots of similar devices available, cheaply, intended for security purposes, mostly. Some are actually Resideo products!
These products seem to have batteries, and I presume I need something similar. But I have no information as to whether HCA30 has a battery, and what voltage etc. Worse, I don't know whether contacts "normally open" (or closed) means open or closed when the window is closed. Changeover would be ideal!
I may have to experiment, but I am confident I can put together something which will do the job at reasonable expense. First, of course, I would like to hear if forum members can help me. Thanks in advance!
