The alarm cannot be programmed to chirp.

However, there are two modifications that can be made that will produce a chirp. One involves replacing a factory part and the other involves incorporating a simple "beeper" into the alarm circuitry. Both seem to be simple mods that you can do yourself. You only need to do one of the mods in order to produce a chirp.

Search for "alarm chirp". Sorry, I do not have the details, but this info will at least get you started.
