Federal Signal Model 2

The Federal Signal Model 2 is an outdoor warning siren produced by Federal Signal Corporation.

Siren Information

The Model 2 features a 2 HP, single-tone 5-port chopper motor, used on the Thunderbolt 1000, another siren once made by Federal Signal. It can produce 3 signals at 102 dBC:

The Model 2 is 25 inches tall, and is about 60 lbs. It can be roof- or pole-mounted, at a recommended 35–40 feet. It is available in two power choices: Model 2-120, running on single-phase 120/125 VAC, or Model 2-240, running on single-phase 240/250 VAC. It can be operated automatically or remotely with an indoor/outdoor Federal RC2W controller.[1]

It features a 100% sheet metal enclosure with polyester powder-coated paint. Protective mesh screens are mounted on the siren's three openings to keep out birds and debris.

This is the most common siren used to call volunteer fire departments in the United States today.

Model 2T

The Model 2T was an omnidirectional siren manufactured by Federal Signal from the 1960s to the 1990s, mainly to fulfill the civil defense requirement for dual-tone warning signals. It had exactly the same design as the Model 2, but instead of a single-toned, 5-port chopper, it featured a dual-toned, 4/5 port chopper which produced 100 dBC at 100 ft. The 2T also ran on 120 or 240 VAC. The Model 2 is still being made, while the 2T's production ended sometime in the 1980s, around the need for civil defense sirens ended.
