The controller comes from this siren unit, the Haztec 8-122-2PL ua-cam.com/video/0n-NoZNYGeY/v-deo.html ...while the siren tones are sourced from the Haztec 8-7110 most likely. ua-cam.com/video/_6DPT8UsrsY/v-deo.html These were most likely sourced from the time when these were exported to Hong Kong in the 2000s and early 2010s. Other countries known to use these sirens are Thailand and Indonesia, although both countries are now pivoting towards original Whelen products. Other siren units like the Senken ELS 205 and 206 copy the tones straight off the 8-122-2 while most other Chinese made siren units use the 8-7110 or Haztec ExpertSL tones. Chinese manufactured siren amplifiers fascinate me with their unusual origins and I hope to be able to catalog more of them soon.
Busted! Don’t sound great either if I’m being honest. Plus I see the “tool” tone and like wail 1, wail 2 on cheap Chinese knockoff sirens. Plus the not actually dual tone mode
