Based on the testing efforts, you may need to implement additional elements, or correct poorly executed tactics. Also, many of your elements may employ batteries, wiring, light bulbs, wireless connections which rely on functional senders and receivers. You need to create a simple, rememberable, sustainable testing schedule. It needs to go on your honey-do's just like mowing the lawn, or taking out the trash. The intervals necessary to keep a system running may require a monthly or semi-annual frequency. If you can simplify your test plan, running through the interval checks you good pretty fast, lending to it's sustainability and insuring you'll actually stick to the maintenance routine.
