Honestly, two years to replace the WHOLE system doesn't sound too crazy, however, if I were them, I would replace them in zones so that there are at least a few sirens active in case something goes awry. I expect some kind of San Andreas thing to happen, this time, no siren warnings.
Shutting off the sirens for two years for upgrades or replacements makes absolutely no sense in the slightest. Two systems can run together, many places do this. Most often setup is along the lines of some old two tone system and some new system with FSK or something, but same principle can easily apply to having two systems. All that'd need to be done is set the polling times slightly different and, if automatic testing, create a slight offset by a minute or so between the two systems.
Then when all is said and done and no more of the old sirens are left, the old activation equipment can then be removed. I'm really struggling to comprehend a reason why it would be straight up shut down for two years.
I own: One complete SiraTone, another SiraTone control module, a 1600W MC, 2 old ATI controllers, 2 round ATI horns with drivers, a ATI-DSA 4 thing, a Federal Signal FC, AR timer and Siratrol, and a small CD&F.
