The Borough of Carlisle at 1 time had 5 fire departments, the two shown are the Federal Fire Siren at the former Empire Hook and Ladder Company and the Model 5 at the current Union Fire Company (there is also a Diaphone in the bell tower out front), the only former station to not have a siren at it was the Cumberland Rescue Company who merged with the Goodwill Fire Company when I was very young, that leaves 2 stations.. the former Cumberland-Goodwill Fire Department and the former Friendship Fire Department. Here is a link to the former Friendship Fire Department on North West Street, there is still an old Fedalcode Model 5 in the belltower there.

The Cumberland-Goodwill Fire Department is on West Ridge Street, on the water tower behind their station is their former siren.... I have looked at it several times in person, it looks like a Sterling but the rotors are wrong on it and the end caps are also wrong. I suspect this is a HOR Super Sirex with smaller end flares and no motor cover but I can't say for sure, you really can't see much of anything on Streetview except for 1 blurry end cap sticking out but here it is:
