Tests have been completed using UniBond Repair Power Expoxy Permanent Adhesive – Metal. Mate-
rial Reference 2000912. Other forms of adhesive exist and local tests should be performed if any other
type of adhesive is used.
A GMXP0 mounting plate must be used when this installation option is selected.
Apply the adhesive to the drill side of the GMXP0 when glue fixing the GMXP0 mounting
plate to a steel surface.
DO NOT apply the adhesive to the rear of the detector
.
Figure 3-7: GMXP0 mounting plate (drill side)
Before fixing the mounting plate to the protected surface, it is important to consider cable access to
the detector. If necessary, rotate the mounting plate to the correct orientation to give cable access to
the detector. When the mounting plate is glued to the protected surface it becomes a permanent fix-
ture on that surface.
The cable access symbol indicates the direction of the cable access to the detector
when the detector is secured to the mounting plate. In the orientation shown here,
cable access to the detector is at the top of the installation.
1.
Protect the detector mounting holes (A) and the GMXS1 mounting hole (B) by placing tape
over the holes to prevent ingress of the adhesive.
2.
Apply adhesive to the drill side of the GMXP0. Do not place excessive amounts of adhesive
on the plate as it will overspill onto the protected surface when the plate is applied.
3.
Use clamps or tape to secure the mounting plate in position for the initial setting time. Under
normal environmental conditions, the UniBond Repair Power Expoxy Permanent Adhesive –
Metal. Material Reference 2000912 takes approximately 10 minutes to set for normal handling
and 2 hours for rough handling.
Notes
1.
Carefully follow the instructions supplied with the adhesive for securing products and all health &
safety advice.
2.
When using the adhesive, it is not imperative that the paint is removed prior to the adhesive being
applied but the surface should be clean.
3.
Securing the GMXP0 with a ISN-SM-90 detector using adhesive will have a slight performance
issue when the detector is set for low shock sensitivity. This reduction in sensitivity should be
considered as part of the design criteria. All other detectors and their associated settings remain
unaffected by this installation method.
4.
As part of any routine inspection, the mounting plates should receive special attention to ensure
that there has not been a deterioration of the adhesive material.

Indirect installation on concrete
The GMXP0 mounting plate must be used to secure a ISN-SM-xx seismic detector to a concrete sur-
face.
Use the ISN-SM-xx drill template (supplied with the detector) to correctly locate the cable access for
the detector and to locate the drill holes for the GMXP0 mounting plate detector and for the GMXS1
test transmitter (if required).
