has not triggered will prevent the audible alarm from sounding during
a failure.

(Not available on 60, 80 and 100kA or JSPR units)
The number of surges detected by the SPD is displayed on an eight digit
LCD display on the front of the JSP door . The LCD counter is battery backed
to maintain the number of surges even during a power loss . Press the reset
button on the counter to reset the surge count .
