DANGER! Sirens produce extremely loud emergency warning tones! Exposure to these

tones without proper and adequate hearing protection, could cause ear damage and/or hearing
loss! The Occupational Safety & Health Administration (www.osha.gov) provides information
necessary to determine safe exposure times in Occupational Noise Exposure Section 1910.95.
Until you have determined the safe exposure times for your specific application, operators and
anyone else in the immediate vicinity should be required to wear an approved hearing protection
device. FAILURE TO FOLLOW THIS RECOMMENDATION COULD CAUSE HEARING LOSS!

IMPORTANT! READ THESE WARNINGS BEFORE CONTINUING!

The Howler™ Supplemental Siren was designed for use in high-risk areas such as an intersection. It is not intended to be, nor should be
operated as a replacement or alternative to the vehicle’s primary siren.

The low-frequency tones of the Howler™ demonstrate significantly different audio characteristics as compared to those of a traditional higher­frequency siren. While the low-frequency tones are better able to penetrate other vehicles, thus alerting drivers to the presence of the
responding emergency vehicle, these tones may also penetrate into the responding vehicle itself. This could potentially expose the operator to
increased noise levels.

To help eliminate overexposure, the Howler™ siren has been designed with a built-in timing circuit. The Occupational Safety & Health
Administration (OSHA) (www.osha.gov) provides information necessary to determine safe exposure times in Noise and Hearing Conservation,
Section 1910.95 (Occupational Noise Exposure). Until you have determined the safe exposure times for your specific application, this siren
should be configured for the minimum operating time and operators should be required to use an approved hearing protection device.
FAILURE TO FOLLOW THIS RECOMMENDATION COULD CAUSE HEARING LOSS!
