Class B Supervised Input Circuits

Figure 4-5 shows Class B supervised wiring from a fire alarm control panel to the

5499.

Use an EOL resistor as shown to enable notification appliance circuit input

supervision. Some panels use EOLs that have a different value from 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).

4.6 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).
