OBO lightning protection device sound and light warning alarm / AS |
Arrester green light that indicates normal state. When there is failure, red light flashing and a loud buzzer peaks presented showing replacement of SPD modules, can stop sound button to temporarily stop ringing, such as within 24 hours, not to replace SPD modules, bee alarm buzzer sounded again. |
