Which external siren to use?

[DotNetDog]

I'm planning my Elk M1G system and right now I am trying to figure out the external siren. I don't know what to use...one of the "speakers" or a "siren"? And the ELK-45 apparently requires 1.2 amps which is more than output 2 delivers.

All I want for the external siren is something that will be located in the attic aiming out of a vent. It's just to get the neighbors attention.

So I am thinking I may need either the ELK-44 or the ELK-SP40. Any suggestions?

By the way, here's Elk's web page that lists them all:

We use ATW bloodhounds on every install. Inside and out. They are good looking, LOUD and small. and very cheap.

I use the ATW Doberman Plus with the strobe light.
