from the system menu. Refer to Figure 3-33 for menu stucture location. For initiating devices
connected to R-NAC expansion cards, refer to Figure 3-34 for menu stucture location. Investigate any

5-2.4 Walk Test
Confirm acceptable fire-signature-entry characteristics for all automatic initiating devices by selecting
“Walk Test” from the system menu. Refer to Figure 3-32 for menu stucture location. Use these menu
functions to confirm that all monitor modules are also working correctly.
