The Powercall DTX Dual Tone "Fierstien Brand" Emergency Siren

This new Powercall Emergency Siren is available now by going to powercallsirens.net/products/...
The Powercall DTX is David Fierstien's latest 2023 version of the DX series Powercall Siren with a DUAL TONE capability. This new siren has a new advanced microprocessor-based technology and features the highest quality circuitry and design, keeping with the industry standard. This siren, just like the UDX7 ,has all newly updated tones, including a "PA-300" sounding Wail and Yelp, which will trigger most traffic preemption systems and gates. It also has a more defined Powercall (Warble) tone, that was taken directly from one of our GE units, the Whoop tone, a Hi-Low, Phaser, Airhorn and the always popular Intersection mode. This siren has exactly the same capabilities as the Powercall UDX7, but is missing the PHASER option, to allow for DUAL TONES.
When running this unit, to get it's full use, you will need to have a 2 speaker setup.
SPEAKER 1 on this unit, will run any of the tones that the normal siren will operate using the selector knobs and buttons.
SPEAKER 2, generates the POWERCALL tone only.
So when you are using the siren, you can use it as a normal 100 watt siren and have all the tones that the unit offers, but when you hit the DUAL TONE button, the additional 100 watts will come from the 2nd speaker and will be the POWERCALL TONE, added to the 1st tone you are already running.
The system also has the industries "FIRST" USB port on the front of the unit that will play an MP3 file you save on the flash drive. Please remember that the USB is not as loud as the actual siren generated tone. The USB also is not meant to be used as an acutal siren. It's more meant for music, sound effects etc. The USB volume and siren volume are controlled by the volume control, but take note that the USB sound is not as loud as the acutal siren generated tone and is used for recreational purposes. Remember that the quality of the MP3 you record on your USB drive is what you will get from the siren. It may not always be clear and blaring loud, remember it's just an MP3 soudn :)
This is NFPA compliant under our highest-powered UDX 87.01 Series board. The UDX series units are our most powerful sirens and have all the features that you can ask for in an electronic siren.
