Should it show on phone?? or do i have a faulty siren ??

Based on our Outdoor Siren Hardwiring Help Center article, it looks like you’ve covered all the right steps here.

Ultimately, the Outdoor Siren’s hardwire terminal block supports 9–28V, 12W DC power input and 22–16AWG gauge wire. Some tips:

  • Do not apply DC power above or below 9–28V, 12W
  • Do not apply AC power
  • Do not use wire gauge above or below 22–16AWG
