Send me your contact info. I know that sirens in the US are 150 but by the time we get them to Canada its 250. I am thinking if I replace the batteries and still don't use it, the new NIMH batteries will still deteriorate, so my spare "fixed" siren will still deteriorate being stored. Soooo you are welcome to it. Send me your email address and I will take some pics of it to see if you still want it. If you do, I will get it out to you.
