I have a copy (in PDF format) of the ACA Penetrator P-10/P-15 manual on my Google Drive somewhere. I also have the latest revision/updated T-128 manual as well (the manuals have changed over the years for the Tempest siren series due to ASC using new parts and whatnot). Federal Signal’s manuals (at least for their newer products) are easily found as they have publicly accessible PDF copies of all their newer in-production sirens on their website,
www.fedsig.com. I also found a PDF copy of the E-Class manual on the same website as I found the T-128 manual on and it is on my computer as well if you’re interested.
PDF copies of the ACA Allertor/Cyclone manuals can be found on the Wiki, accessible at wiki.airraidsirens.net. I am in the process of getting the T-128 manual and E-Class manual onto the Wiki so they are available for anyone to download. ASC manuals are a little harder to get because you have to send them a message to get copies of their materials, including sell sheets, which is why I was lucky to find PDF copies of both of those manuals on another PDF sharing website, and when I found them I didn’t hesitate to download them because they’re not easy to come by.
Also, Sentry Siren does not make manuals publicly accessible either. I believe they are only made available to Sentry dealers and installers.
Hope this helps.
