Chris, First you need to determine if your repeater controller can generate the tones. Two tone paging was a feature in controllers made by S-Com, ACC and others. As long as the controller can generate the sequence it should work well. If the controller does not support two-tone paging then if you have logic outputs you could use an add-on board from Communications Specialists that will generate a single tone sequence.
As for pagers, parts are hard to imposssible to find for most pagers. Since the paging market dried up with the advent of cell phone based text messaging the supply of pagers has also dried up rather quickly. A word of caution about pagers; they use an antenna that is a compromise at best. It is physically and electrically small. Only at UHF does a pager antenna come close to being able to approacha quarter wavelength. As a result the performance of pagers is poor compared to an HT. Most paging systems run very high power to compensate for the poor performance of the paging receivers.
