Atlas IED AS100N Data Sheet
Compression Drivers for
Electronic Siren Loudspeakers
SD-70, AS100N
Features
• Choice of 58 Watt or 100 Watt Power Handling for High Intelligibility
and Sound Penetration
• Heavy-Duty Weatherproof Construction
• Specifically-Designed for Electronic Siren and Signaling applications
• Accommodates Most Horns and Reflex Horns with Standard 13⁄8" – 18
Thread Pattern
Applications
Depend on the Atlas Sound SD-70 and AS100N compression drivers
for elec tron ic siren and signaling needs on emergency and law enforcement vehicles, as well as for use in stationary and mobile public address
systems. SD-70 and AS-100N provide maximum power conversion with
low-amplifier output to fulfill high-intelligibility and sound-penetration
requirements. The Atlas Sound SD-70, rated at 58 watts RMS, is recommended for medium-power systems such as commercial and industrial
warning systems. The Atlas Sound AS-100N, rated at 100 watts RMS,
is recommended for high-power systems in public safety, civil authority,
military, or emergency medical applications. Either unit can be used with
most horns or reflex horns equipped with the industry standard 13⁄8" – 18
thread pattern.

SD-70
The 58 watt SD-70 and the 100 watt AS100N compression drivers
are standard components of Atlas Sound's electronic siren loudspeaker assemblies. Weatherproof units are ideal for use in police, fire,
ambulance, and utility vehicles. SD-70 is recommended for mediumpowered systems; AS100N for high-powered systems. Drivers are
equipped with a non-fatiguing, self-aligning sound chamber assembly
containing a 23⁄4" phenolic diaphragm with a nominal impedance of 11 Ω.
Replacement head assembly, the Atlas Sound K-70GB is available for
field replacement of SD-70 and the Atlas Sound K-100N for AS-100N.
Product series is suitable for use with matched amplifier and control
equipment in systems requiring AMECA (Automotive Manufacturer
Equipment Compliance Agency, Inc.) certification to General Services
Administration spec i fi ca tions (KKK-A-1822C). The AS100N is constructed
using an NEODYMIUM-IRON-BORON magnet.
