Lift Truck Backup Alarms
A
B
These alarms beep loudly and repeatedly when a vehicle moves in reverse. Wire them between the vehicle's battery and reverse lights. Alarms are resistant to vibration, dust, and moisture.
Alarm with automatic volume control detects the sound level around a vehicle and sets the alarm volume 5 dBA above that level.
Optional backup alarm switch activates the alarm when you shift into reverse, so you can use the alarm on a vehicle without backup lights.
