4.3 GMXS5 – External test transmitter
The GMXS5 external test transmitter is mounted on the exterior of the protected area to enable a
functional check of the seismic detection system by simulating an external attack. During the test
period the GMXS5 creates a series of mechanical oscillations which are transmitted to the seismic
detector(s) as structure-borne sound. If the seismic detectors are correctly spaced and configured,
then the test is detected and an alarm is triggered.
The GMXS5 has an operating radius that is directly linked with the operating radius of the detector
that is being tested. The GMXS5 is capable of testing multiple devices.
See Figure 4-8: Activate 4 detectors from a single GMXS5 for more information.

Figure 4-6 shows the electrical connection for the device, 12 VDC, tamper (Sabo) contacts and a
selectable switched input are the available connections.
