Auxiliary Siren: Low temperature operating limit?
What is the low temperature operating limit for the 105db auxiliary siren?
Winter temperatures here commonly dip to 20F or 10F or even 0F for days on end.

I have the extra siren outside and we had a night during Christmas where it got down to 16 degrees and it still was working, now when it gets that cold for a period of time it may drain the batteries faster but it will still work

Hi @rln,
The operating temperature of the Auxiliary Siren is 32-102F. However, as Lance mentioned, it can still work in lower temperatures.

Thanks for both your responses.
I am curious whether the stated operating temperature limits mostly hinge on the effect of extreme temperatures on the batteries or some other component of the siren itself?
From what I've read online, lithium iron disulfide AA batteries, e.g., Energizer Ultimate Lithium Ion, will tolerate cold temperatures much better than the alkaline AA batteries.
