The Penetrator series is a series of rotating sirens by Alerting Communicators of America that mainly consisted of 4 models: The P-10, P-15, PN-20, and the P-50.

P-10

This model was the first to appear, slightly after the Allertor 125 and the short-lived ACA Howler, and was designed as the successor of the Allertor 125 to perfect the design faults the Allertor had. Early versions of this siren were labeled as Allertor 125s as the siren was originally just a custom horn option. It uses the same 10 HP motor to drive the 8 or 9/12 port stator. This model can sometimes be differed from its look-alike twin, the P-15, by its intake cone. However it depends, because the dual tone P-15 shares the same intake cone as the P-10 does. The P-10 does not use the cylindric intake found on single tone P-15s. That is limited to the P-15 only.

This siren was nearly identical to its older brother, but is instead powered by a 15 HP motor. Some models have been equipped with dampers in the tube to create coded signals. After the American Signal Corporation change, this siren became known as the RM-127 and the 9/12 port option of this siren was discontinued.

Type Electronic
Sound output 124
Succeeded by WPS-4000 Series (1990)

This type began as the problematic Performance+ Penetrator, made especially for Dane County, Wisconsin. The siren was intended to be 100% DC, but was never perfected, and thus the project was scrapped. The PN-20 uses the 9 port rotor from the Screamer S5 with a 20HP motor. Post-ASC, this siren was renamed to the RM-130. The siren was later succeeded by the T-128. thumb One of the only active PN-20s in the entire world active in Lockport, IL

The P-50, later known as the RM-135 and T-135-AC, was the biggest model of the Penetrator series, packing a massive 50HP motor pushing a sound output of 135dBc @ 100 feet. It is vastly different from its smaller brothers sharing its rotor and stator with the Cyclone 120. It holds the title of the world's loudest dual-tone siren as well as the loudest electric powered siren, and is to this day the loudest rotating directional siren in the world. This powerful siren was eventually succeeded by the more modern T-135 AC/DC.
