General Electrical Connections

There are a number of different connection options for the monitoring of the seismic detectors
available from the SPC system. Bosch Security Systems recommend that the dual end of line op-
tions are selected, as they provide the most comprehensive coverage and reporting.
Optimum performance of the combined SPC/ISN-SM-xx system requires selection of the financial
package in SPC. See Section 9.2 for more information on the additional benefits.
The list of available end of line monitoring is as follows and the default value is Dual 4K7/4K7 end
of line resistor:
Figure 9-1: End of line monitoring options
Note that resistors are not supplied with ISN-SM-xx seismic detectors.
A quick comparison of the benefits between single and dual end of line monitoring follows:

Note: the SPC panel detects the different resistance values and reports the condition to the user of
the SPC system as detailed in the status column.
The electrical connection for seismic detectors (ISN-SM-30, ISN-SM-50, ISN-SM-80, ISN-SM-90) is
detailed in Figure 9-2.
