Length Of Life Of Wireless External Sounders

[bennynoneck]

I know this probably depends on how many times it goes off, but on average how long do you think a X/W Odyssey from Texecomm would last on a set of batteries?

 

Thanks.

The times quoted by Texecom are 4 years with the comfort LED's off or 2 years with them on. How that compares with reality will remain to be seen...
