Description
72612 NARVA REVERSE ALARM COMPACT 12/24V
With all the features of the other compact alarms, this reversing alarm will automatically adjust to a minimum of five decibels above surrounding noise, reducing the irritation of a high-level sound when a lesser sound level is appropriate. Ideal for airports, hospitals and areas where surrounding noise can change rapidly
Caution: Self-adjusting alarms must detect surrounding noise to properly adjust sound output. Mount alarm at rear of vehicle facing outward, clear of obstruction that would impair noise levels
