I have an old garage with a pull up door where I store some expensive bikes. It's a pain in the neck to lock it and even when I get it locked, the padlock can easily be cut with boltcutter. I'd like to put a magnetic contact sensor on the door, such that when it is opened between the hours of about 10pm and 7am, a loud alarm sounds and strobe lights flash. Our bike thieves are not particularly sophisticated. I'm sure the alarm and strobes would scare them off. Plus our bedroom is close to the shed.
I'd like to be able to power the alarm by plugging it in to an outlet in the garage with a plain old analog timer that will supply power to it between 10pm and 7am. I don't want anything battery powered or wireless. I don't want a smart system that connects to my phone. I want to be able to set it up, set the timer and forget about it.
I can't seem to find any ready-made products online that do this and I have no idea what to Google to get some guidance. It would be great if someone could tell me what terms to Google or what products to look up. I'm pretty handy but haven't done any electrical. Thank you in advance for any help.
