I just recently purchased a FS PA150 siren in really great shape. After reading info about this siren, it says that it’s very similar to a PA200 except that is has a wired-in mic and PA/manual settings. So I went to the FS website and it also states the PA150 has a wired-in mic mounted underneath the siren box. Here’s the thing….my PA150 doesn’t have a wired-in mic. On the back of the unit, it has a connection to add a mic. My question is….do I have a rare siren because of this? Or was this a feature added just before they were discontinued?
That's strange. If this is an add-on by an installer, who ever did it made it look factory. I guess the factory mount underneath gets in the way of other equipment...so i assume they mount a rear mic for clearance as an option.
That was another question i was going to ask. Federal states that PA150s can begin with either "T1A" or "Y1A". The serial number on mine is different because it begins with "N1A." So it makes me wonder if this feature was changed by Federal at sometime.
