Figure 4-9: External GMXS5 and internal GM760
Figure 4-9 shows the detectors mounted internal to the protected space and the GMXS5 mounted
external to the protected space. This location provides a stringent test for the detectors as the test
signals from the GMXS5 have to travel through the wall.
Figure 4-10: Activate 3 detectors from a single GMXS5
