Federal Signal - Model DSA -High Powered Directional Speaker
Federal Signal’s Directional Speaker Array (DSA) provides excellent voice and tone reproduction and is ideal for overcoming high levels of industrial noise. Design flexibility allows the user to combine up to four speaker arrays; each array will hold from two to six re-entrant speakers. Speakers have a 70° horizontal angle of dispersion, accommodating specific sound output patterns. (When vertical stacks are placed 90° apart, a 180° horizontal coverage is possible.)
- Overcomes ambient noise of industrial environments
- Provides maximum speech recognition and tone reproduction
- Produces 111 dBc to 121 dBc at 100 feet
- Two mounting kits available
- UL and cUL listed
- Standard models include 45 feet of cable, DSAx-models include 94 feet of cable
The Model DSA mounting kits allow for multiple speaker arrays to be mounted on the same pole at 90° increments. The downward tilt can be adjusted by 15°. The mounting flexibility of this system allows the speakers to be pointed directly at a targeted area for more concentrated sound output.
A DSA consists of a corrosion-resistant aluminum frame with fiberglass projectors and stainless steel mounting hardware. Each speaker contains a high-efficiency 100-watt driver. DSA speakers are equipped with 45-ft UL rated PVC shielded wire. The DSAX-1 speakers are equipped with 94 feet of UL rated PVC shielded wire.
Amplification, tone generation, and signal timing are provided by the UltraVoice® controller, purchased separately.
Ideal for outdoor industrial plant warning, the DSA speaker array allows sound coverage to be customized to each site, preventing wasted sound in and around the plant. The DSA provides better speech intelligibility within its coverage zone area.
