Directional Speaker Array Electronic Siren

Category: Outdoor Notification

Federal Warning System's Electronic Directional Speaker Array, model DSA, is comprised of 1, 2, 3 or 4 vertical support structures with two to six re-entrant speaker array projectors mounted on each vertical support stack. Each vertical support structure can be positioned at 90° or 180° intervals (refer to specification sheet). Each speaker array has 70° horizontal angle of dispersion. When the vertical support stacks are positioned at 90° apart, a 180° horizontal coverage is produced.

A vertical support stack consists of an aluminum structure with fiberglass speaker array projectors, stainless steel mounting hardware and one commercially available 100 watt driver per speaker. The DSA is available in several models, DSA2, DSA3, DSA4, DSA5 and DSA6. Decibel output range is from 111 to 121 dBC. The DSA speaker array requires no maintenance except for periodic speaker tests.

Signal Description: The directional speaker array provides excellent voice reproduction and with the aid of the UltraVoice Controller (purchased separately - see related products to the right) will produce the following warning signals:
