Federal Sign & Signal | 3T22 | Request Hi-Lo | Alexander, NC | Roblox
©️2020-2026 The Broken Thunderbolt. You are ONLY allowed to use my content for compilations. Siren notes: Recently repainted! Non-functional top damper. The wire was never hooked to it. Fully functional lower damper. This is the first time this 3T22 has run the "Hi-Lo" signal since installation. Installed: 1966. Originally was on a single pole. Termites ate at the pole. Replaced: Federal Electric Type Mach. B Other notes: Double-pole-mounted 3T22s are very nice looking. I love double pole-mounted sirens. Join the Discord! If you want to. / discord
