Elk-110 Siren Driver Question

I am planning on adding a elk-110 siren driver to my vista system. First Off, I am wondering how much power it will take from my Vista 20p and how well it will run. Second, I have E-70 speaker strobes on the system, I am hoping the Fire message can play over the speaker strobes. Is this possible?

  1. This depends on how you want the system to be set up. For reference, the voice siren driver info can be found here: Voice Siren Driver Module - ELK Products
    In particular, how will you be connecting the siren driver?
  2. How many speakers will you be having on the system? With these systems being 12 volts and the E-70 being 24, they’re going to be rather quiet.
