5-5 Activating Floating Blanking
Floating Blanking (either one- or two- beam) is activated by setting positions 5 and 6 of Switches A and B located
inside the receiver end cap. Refer to Figure 3-1 and Table 5-5. Any mismatch between the settings of Switch A
and B will result in an alarm condition. To access Switches A and B, remove the four captive screws which se-
cure the largest receiver end cap. Set these switches before mounting the receiver. Use of the program button
is not required.
Note:
When ECS or Floating Blanking is active, the amber ECS/FB Indicator will illuminate to indicate that the
F3SL system is operating in a less sensitive state.
