First, if you can help, thanks a lot. With how busy we all are it's wonderful when people take the time to post thoughtful and helpful replies. I've learned that it's very difficult to find objective information regarding home security systems. I want the ease of wireless but have 4 patio doors + 2 standard doors, so I'd need 6 door sensors and would also like at least one infrared detector that my cat won't set off. Any opinions on which brand or brands are best for me? Keepsafer? Simon 3? Visionic? I'd like to keep this as cheap as possible (of course sometimes extra dollars are worth it -- perhaps you can help me there too). I don't plan to pay for a monitoring service. Any ideas? Thanks so much. Emily

I think I already know the answer to my question from reading the forum, but here goes...I recently moved my small business to a new facility which has an existing Chubb monitored system with panel, keypad, siren, two door sensors, and two motion detectors. The property's been vacant for several months, so there's no monitoring agreement. All appears to be functional with zone LEDs lighting, etc. I've disconnected the telephone wire, but everything else is intact. (If Chubb uses another manufacturer's equipment, I haven't looked to see the make/model, etc.) I can't afford monitoring at this point, but it would be nice to have a working system dial my cell/pager on intrusions. Is there any way to reprogram the PIN and program the dialing, or must I buy a new panel, keypad, or both? What options do I have? And, can you recommend a parts source? Thanks in advance...
