DSA. DSAMKSPB45 Mounting kit for 4.5-inch steel pole. Includes two brackets, two u-bolts, and mounting hardware for one DSA2, DSA4, or DSA6 speaker. Federal Signal recommends using two I-IP100-PMW brackets. See Figure 6. DSAMKSPB23 Mounting kit for 2.375-inch steel pole. Includes two brackets, two u-bolts, and mounting hardware for one DSA2, DSA4, or DSA6 speaker. -
Page 10: Wiring Options
DSA2 Wiring Options A DSA2 speaker requires 200 watts of power, which uses 50% of a single UV400 amplifier. Use a single UV400 amplifier to power two DSA2s that are wired in parallel for a total power of 400 watts. A UV Controller equipped with eight UV400 amplifiers can power up to sixteen DSA2s. -
Page 11: Installation Instructions
800 watts. See “Figure 20 Wiring Options Continued.” Mixing DSA Speakers Wiring Options DSA4 speakers always use a single UV400 amplifier. You can mix DSA2 and DSA6 to use the UV400 amplifiers efficiently. When wiring different DSA speakers together, be careful to follow the wiring diagrams to ensure drivers are always in series or series/parallel arrangement. -

Page 18: Wood Utility Pole Installation
When the installation requires the use of the DSAMK4 mounting bracket, you must make a circular plate and rigidly attached to the top of the pole. Figure 15 shows the required bolt hole pattern for those brackets. Directional Speaker Array (Models DSA2, DSA4, and DSA6) Federal Signal www.fedsig.com... -
Page 19: Figure 10 Dsamk1 Bracket Dimensions
Installation Instructions NOTE: The pole top mounting holes are at a 45° angle to the speakers’ horizontal centerline. The balance of the installation is similar to that for a wooden utility pole installation except that the installer will provide grade 5 machine screws, washers, and nuts for attachment of the siren brackets to the pole brackets. -
