ProALARM is a failure indication device that indicates the need to replace a failed SPD. It can be easily installed next to the SPD on the same rail by making connection between the RC contacts of the SPD and the unit.
If the SPD fails, a loud audible beeping sound and the red LED illuminates.
Pressing the button will silence the audible sound, but leave the LED illuminated until the SPD has been replaced.
