Tips on removing sirens from poles?

[fullsendersonly]

I’d caution trying to saw the pole off, again that wiring is still connected and may be live; and there’s not much in terms of leeway to get between that and the beams the siren rests on. You might just have to come equipped with plenty of penetrating oil, patience, and an angle grinder.

PB blaster and my hammer and my wrenches,blowtorch,grinder are my best friends. I will try to carefully remove this siren.
