5.3.4 Clear Verify Counters
Prior to an alarm, a detector may go through a verification sequence to make sure it is not a false alarm. From the Alter Status menu,
once you type in a node address and press the CLEAR VERIFY COUNTERS soft key, the screen in Figure 5.10 is displayed. This action
will reset verification counters for that node, preventing an inaccurate verification reading if an alarm is subsequently activated.
