Vanderbilt GM775LSNi Installation Seite 4

The GMXP0 mounting plate can be used for installing a
seismic detector on a concrete surface. It is essential to
use the correct side and mounting methods. The
GMXP0 displays a detector symbol to indicate the
direction of the cable access to the detector.
Take note of the orientation of the GM775LSNi seismic
detector and the required orientation of the GMXP0
mounting plate.

1. Use the GM7xx drilling template (provided) to determine the
location of the required holes.
2. Drill a 10mm Ø x 60mm hole and insert the steel expansion
plug.
3. Drill a 5mm Ø x >22mm hole and insert the GMXS1 brass
expansion plug.
When installing on concrete, the GMXS1 must not have
any contact with the GMXP0 mounting plate. The
GMXS1 must be attached to the concrete using the M4
x 21mm screw and the associated brass expansion
plug.
4. Secure the GMXP0 to the steel expansion plug with the M6 x
47mm screw.
5. Secure the GMXS1 to the brass expansion plug with the M4 x
21mm screw.
6. Mount the detector on to the GMXP0.
6. Mounting the detector
1. Remove the cover from the detector.
2. Attach the detector to the prepared mounting base using the
two mounting screws (Fig. 1, items I).
3. Remove the cable access skirt (Fig. 5).
4. Wire the connection cables to the terminal (Fig. 1, item B) as
shown in diagram (Fig. 6).
5. Secure the cable to a cable anchor (Fig. 1, items C) with a
cable tie (provided).
6. Connect the accessories and program the detector.
7. Remove the pre-formed cable access points as required to
enable cable access through the skirt (Fig. 5).
8. Replace the cable access skirt.
The cables connected to terminals 8, 10 and 11 must not
exceed 3m in length.
The polarity of the LSN Bus must be maintained.
The screen from the LSN cables must be connected into
terminal 7.
7. Accessories
All of the accessories (Fig. 7) have their own installation
instructions, which are supplied with each accessory. These
installation instructions should be followed for the correct
installation and optimum performance from this seismic detector.
For ordering information, see section 16.
8. Configuration (addressing LSNi/LSN)
GM775LSNi supports LSNi (LSN improved) and LSN (LSN
classic). The detector must be configured using the two DIP
switches (Fig. 1, items G and J) before the power supply is
connected via the LSNi/LSN bus. The DIP switches are used for
configuration and addressing as follows:

Fig. 1, item G – Addressing

Fig. 1, item J – Material and coverage application
The following configurations are possible:
A6V10276498_b
8.1. External tamper contact
The detector provides the option of connecting an additional,
external tamper contact (for example, the GMAS6 or the GMXP3).
Connect the external tamper contact to terminal 11 Ext. Sabo and
terminal 8 GND (Fig. 6).
The external tamper contact is enabled via the DIP switch (Fig. 1,
item J) with switch 2 in the ON position as follows:
ON
OFF
8.2. Remote sensitivity input (Fig. 6, terminal 10)
When this input is active, the sensitivity of the detector is
reduced. The sensitivity input should only be applied
under special circumstances, and only for short periods
of time. Any reduction in sensitivity must comply with
applicable regulations such as VdS in Germany. Remote
sensitivity is activated by linking terminal 8 to terminal
10.
Sensitivity is reduced to 12.5% of the original setting for the
duration of the remote sensitivity input. A potential application is
the prevention of alarm triggering where loud functional noises
prevail
9. Programming via LSNi/LSN control panel
The detector is programmed using the configuration software of
the corresponding control panel.

This mode enables compatible
use of GM775LSNi in existing
installations to replace a
GM570LSN detector.
The detection characteristics are
identical in all configurations.
