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.

Narva alarms are manufactured by Preco Electronics, the inventor and original patent holder of the reverse motion alarm. Famous for their quality and dependability, these alarms are use by nearly every major OEM (original equipment manufacturer) in North America, Europe and Australia. All alarms feature solid state electronics sealed in urethane for protection against moisture, dust and vibration. The alarms are steam cleanable, voltage spike protected and have a broad temperature rating of -40°C to 85°C, making them suitable for all conditions across Australasia.
