bell or siren?

[tomtnt]

I hooked up my elk to an existing alarm which had a bell - was wondering what the advantages of bell versus siren were?

thanks

Bell only gives you one tone whereas siren gives you variable tones. I would also be concerned with the current draw on the bell? I generally see bells for stand alone fire installations. I think that people would pay more attention to a siren than a bell. BTW, if it's a UL installation speakers are not allowed.

As stated above, mainly current draw. Look up posts by me with "moose" and search for the Moose Piezo Sirens for an example.
