Hi! It's been a few years. Got out of the building and security business a few years ago. Now, even with this tanking economy, I'm back. Don't ask about my IQ - life is what it is and I try to go with the flow.
Anyways, I'm trying to get back up to speed on stuff. Especially PIRs and cat/dog friendly detectors. Also, is GRI still "the" vendor for switches? Lotsa questions. Where do I start? I don't want to clog up this place with redundant info. Any suggestions on sites for re-learning and learning? Or, any other suggestions?
Tough times often call for better solutions.
