Class B Supervised Input Circuits
Figure 4-5 shows Class B supervised wiring from a fire alarm control panel to the Model
5499.
Use an EOL resistor as shown to enable notification input supervision. Some panels use EOLs
that have a different value than the 4.7k ohm EOL resistor used by the 5499. In this case, the
EOL must be UL listed for the fire alarm control panel (not the 5499).

4.7 Ground Fault Detection Enable/Disable Jumper
In some cases the ground fault detection feature on the 5499 may interfere with the ground
fault detection feature of the main control panel in the system. To disable the ground fault
detection feature on the 5499, place the jumper block on J1, across pins 1 and 2 (see Figure
4-2).
