ACA P-15 [Remastered]

Penetrator Series:
10 and 15 HP models were nearly the same, aside from motor used. The P-50 was and still is the loudest dual tone siren in the world. The P-15 (Single-tone) and P-50 were still being produced by ASC until 2002 and 2007, under different names (P-15 being the RM-127 and the P-50 being the RM-135/T-135 AC). The PN-20 was the last siren made by ACA. These were a DC powered counterpart to the P-15. They were equipped with battery backup. The PN-20 continued into the ASC years under the name RM-130
