I no longer live in house that had AT&T security system and no longer have a stash of parts to share.
AT&T Home Security System components are a little hard to come by because they have been out of production for so long.
Luckily, the system components were manufactured with some quality to them and so failures are infrequent.
Will note here that universal transmitters do use crystals in them to control transmit frequency and crystals do age and the transmit frequency drift and perhaps enough to impact the central controller "hearing" them.
The AT&T smoke detectors are unlike those sold in most big box hardware stores in that the AT&T uses light to detect smoke particles rather than some sort of radium source thus if the AT&T smoke detector is cleaned occasionally it has an infinite life span.
Magnetic switches used with universal transmitters and wireless keypads attached to doors and windows, are available from many Internet sources. You want the kind that is normally closed (NC).

eBay is always a good source to check for AT&T Security System parts.
Sears Parts Online now is carrying some AT&T home security system components.
