The Multi-Frequency back-up alarm provides a solution to potential noise pollution created by back-up alarms in confined or densely populated work areas by maintaining a safe warning signal for those in the danger zone of backing vehicles while minimizing disturbance to work site neighbors. The Multi-Frequency alarm operates by emitting sound at multiple frequencies attenuated above 4000Hz so that the sound is perceived to dissipate more quickly than a conventional pure-tone alarm.

• Back-Up Alarm; Multi-Frequency; 87 dBA; 2-Bolt Mount; 12-24V DC; 0.34 amps; Approvals: SAE J994 Type D, CE, R10, RCM, AMECA; 2.8"H x 4"W x 1.6"D; Signal is more directional & perceived to dissipate quicker than pure tone; Epoxy Sealed.
