The Powercall 86M is the latest 2024 "Fierstien Brand" Emergency Siren. This unit was designed and certified by David Fierstien of Powercall Sirens LLC in Northern Virginia. All circuitry, certifications and build specifications are the sole property of David Fierstien and Powercall Emergency Sirens(r). This unit is a 100 watt emergency siren that has a small remote head, giving you the "Longer Wail Tone" as requested by many of my customers. The industry standard Yelp, a smoother "Less Break" Powercall Tone as requested by many of my customers, the whoop and the intersection tone. Pair with that the electronic airhorn, enclosed in a small LED lit remote head and you're ready to roll.

This is a 100-watt siren that can be wired for 100 watts using one speaker, like my Powercall 6DX. The unit can be powered by any 100 watt siren speaker as long as that speaker is not hooked ot any other unit.
