GMXS5 external test transmitters are installed externally on walls C and E in position 3 and 3. In
this example, the floor, ceiling, and rear walls are not externally accessible and so the detectors in
these areas are tested by using GMXS1 internal test transmitters.
P
ractical sensitivity and noise checks should always be performed before the installa-
tion is completed.
Exact detection range and capabilities can only be determined by practical tests on
site.
In Figure 6-15 and Figure 6-16, the detector layout is shown for the same application.
Figure 6-15 shows the positioning of the internally installed detectors with the associated detection
radius for each detector.
U
sing a scale drawing of the room to be protected and adding the detection radius is a
good method of verifying a system design.

Figure 6-16 shows the GMXS5 external test transmitters mounted on the exterior of the vault at C3
& E3.

Figure 6-17 shows the detector location and the detection radius for each detector. This is an ex-
ample to demonstrate that each surface of the vault has comprehensive detection coverage. The
