The Powercall X71A siren is David Fierstien's 2019 X Series 2 tone, remote emergency siren. The X71A sounds the Powercall (Warble) tone and the Whoop Tone. The unit is a remote siren that is controlled by a supplied 2 position momentary toggle switch which comes with the unit. Each position on the switch will activate one of the tones and de-activate the tone as well. You can always use your own triggering system, as long as the device throws out a momentary negative signal. The X71A requires one 100 watt speaker (Not included) and is a great undercover, remote siren.

This siren requires ONE speaker (Sold Separately) and CANNOT be used with 2 speakers. Our recommendation for a speaker is our Powercall 6DX Siren Speaker.
