It's not clear whether you want the PIC to just turn on an external gizmo
that makes a police siren sound, or have the PIC generate the sound.  If
the latter, my HAL project might be relevant.  It randomly emits various
sounds stored in program memory.  The sampling rate is very low, so I get
about 7 seconds from a 16F876.  An 18F252 should give you rougly twice as
much time, or the same time at twice the sampling rate, etc.  The HAL
project is described at http://www.embedinc.com/pic/hal.
