The City of Tyler is committed to the safety of all who live, work or visit here. The Outdoor Warning System is another example of this commitment. The Outdoor Warning System is activated to alert the public of a specific situation that may occur. These warnings may be issued for specific geographical areas that may be affected. The Outdoor Warning System allows for both tone and voice alerts to the public. When the sirens are activated, people are encouraged not to call the Tyler Police Department, but to turn on their radio or television to obtain further information. The specific situations are as follows:

Attack Warnings

Attack Warnings are issued when there is a threat of attack on the United States or portions of it.

An Attack siren will sound like this: Attack Warning Tone
This tone will be transmitted for 3 minutes.

A voice alert of instructions is then transmitted over the system.

Fallout Warnings

Fallout warnings are intended to warn of radiation hazards resulting from nuclear detonations, accidental mishaps, and/or terrorist incidents.

A Fallout Warning siren will sound like this: Fallout Warning Tone
This tone will be transmitted for 3 minutes.

A voice alert of instructions is then transmitted over the system.

Natural (Tornado) and Technological Emergency Warnings

This type of warning may be issued to cover the following events: major natural disasters, errant domestic missile launch, reentering space debris, volcanic eruption, major dam failure, and other hazards to public health, safety, and property that may threaten a wide area.

A Natural (Tornado) and Technological Emergency Warning siren will sound like this: Natural and Technological Emergency Warning Tone
This tone will be transmitted for 3 minutes.

A voice alert of instructions is then transmitted over the system.

Testing

The Outdoor Warning System is tested monthly on the first Tuesday of every month at 11:00 a.m. In the monthly test, the steady ATTENTION or ALERT tone will be sounded for one minute.

The testing siren will sound like this: Testing Tone

A voice alert indicating that the activation of the system is a test, will be heard.

The testing tone will then be followed up with the All Clear Tone which sounds like this: All Clear Tone
The wavering ATTACK WARNING tone will not be used for tests.
