Outdoor Warning Siren Systems

T-I35-AC siren is the world's most powerful siren.
The T-l35-AC™siren is a 135 dB rotational directional siren designed for large urban and rural communities and nuclear power plant Emergency Planning Zones. Because the T-l35-AC™is the world's loudest siren, it will cover the same radial area as four (4) 127 dB sirens, and reduce the number of sirens and associated installation and maintenance costs necessary for your community.

System Design
The Rotational T-l35-AC™Siren utilizes aluminum sound-producing components which are covered in color-impregnated fiberglass to eliminate rusting and painting maintenance. Sirens are mounted directly over the center mounting poles so that guy wires are not required. The T-135-AC™are the world's largest sound-producing sirens capable of covering over 9.9 square miles. In comparison, the 125-128 dB at 100 ft.-rated sirens cover 2.2 to 3.1 square miles (a 4 to I ratio), making the T-l35-AC™ siren very cost effective for large area warning signals.

Activation
The T-l35-AC™can be activated by using landlines (hardwired relays) or by radio controls. Various encoding formats allow for tone activation of multiple siren signals. Two items are required: an encoder at a central dispatch location, and a Universal Remote Terminal Unit (U-RTU) mounted at the siren location. The U-RTU is interfaced with the MC-35-3 Siren Motor Control. American Signal manufactures a complete line of radio controlled systems.

Installation
The T-135-AC™should be mounted 65' to 75' above ground level per FEMA CPG 1-17 and for maximum sound dispersion. Controls should be mounted 10' to 15' above ground to discourage vandals.
