The number
Ground shunts cause missed alarms: The possibility of “ground shunts” increases significantly if you don’t install the resistor at the end of the line. If you install the resistor for points 1 to 8 before a detection device on the sensor loop and the loop becomes grounded after the resistor, any devices beyond the ground are “ground shunted”. Alarm or trouble conditions beyond the ground are not seen by the panel.
