Only in walls with a cavity. Concrete or masonry walls won't work, or walls filled with insul.

They tell me they get this question and the mfg says it won't work. I assume in your actual experience you have had success through walls contrary to what the mfg reports. Chris Cahill, P.E.

It works in high ambient noise conditions, at significant distances, and around or through most obstacles. It is only "listening " for a specific high frequency sound emitted by the leak. _______________________________________________ Sprinklerforum mailing list http://lists.firesprinkler.org/mailman/listinfo/sprinklerforum For Technical Assistance, send an email to: [email protected] To Unsubscribe, send an email to:[email protected] (Put the word unsubscribe in the subject field) _______________________________________________ Sprinklerforum mailing list http://lists.firesprinkler.org/mailman/listinfo/sprinklerforum For Technical Assistance, send an email to: [email protected] To Unsubscribe, send an email to:[email protected] (Put the word unsubscribe in the subject field) _______________________________________________ Sprinklerforum mailing list http://lists.firesprinkler.org/mailman/listinfo/sprinklerforum For Technical Assistance, send an email to: [email protected] To Unsubscribe, send an email to:[email protected] (Put the word unsubscribe in the subject field)
