ProAlarm II

ProAlarm II 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 a connection between the RC contacts of the SPD and the unit. If the SPD fails, a loud audible beeping sound is heard, and the red LED illuminates. Pressing the button will silence the audible sound, but leave the LED illuminated until the SPD has been replaced.
