vista 20p and a 714 blaster driver module

[LJP602]

Getting close to finishing my system replacement and have a question of
compatibility. I can't seem to find a reference to it on the Honeywell site.
My old system had a horn and a 714 blaster driver and I am wondering if I
can use it for the sounder in the vista 20p system. Seems like the voltages
match but did find a reference on line to the need for a resister in the
circuit so the driver does not draw too much power. Any one out there have
any experience with this setup or some advice for us newbie's.

Thanks Larry

Thanks for the insight, Nick, I have a few dc transformers around, is it ok
to use them to power the 714 and if so how much power would it draw?

Thanks Larry

The blaster driver draws way to much power your either going to have
to use an additional power supply and relay or go to a low draw
driver, you can reuse the horn part thou.
