SOUND HAZARD
All effective sirens and horns produce loud sounds (120 dB) that may cause permanent hearing loss.
Always minimize your exposure to siren sound and wear hearing protection. Do not sound the siren
indoors or in enclosed areas where you and others will be exposed to the sound.
After installation, test the electronic siren to ensure that it is operating properly. The siren is designed to
blow the fuse under reverse polarity conditions. If the fuse fails when power is supplied, check and correct
the power lead wiring. Install a 15 A in-line fuse and re-apply power.
