LSN application in GM570LSN
compatibility mode
This mode enables compatible
use of ISP-SM90-120 in
existing installations to replace
a GM570LSN detector.
The detection characteristics
are identical in all
configurations.

8.1.
External tamper contact
The detector provides the option of connecting an
additional, external tamper contact (for example, the ISN-
GMA-S6
or the
ISN-GMX-P3S). 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
Switch 2 ON = Internal tamper
contacts only
OFF
Switch 2 OFF = Internal and
external tamper contacts
Link terminal 8 to terminal
11 to prevent a tamper
signal (Fig. 6)
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.
10.
Effective operating radius
The specified operating radius applies to an attack with an
oxygen lance. If attacked with a mechanical tool (e.g. a drill)
the value may be as much as three times higher. The
specified operating radius is a guideline which is heavily
influenced by the characteristics of the material and the type
of construction.
11.
Shock sensitivity
Shock sensitivity defines how the detector responds to
individual strikes to the substructure of the detector. It is
only possible to set the shock sensitivity for the mode and
effective radius independently in USER MODE with the
LSNi/LSN control panel.

*Modes not available in GM570LSN compatibility mode
*Availability of these options depends on the ability of the
control panel to identify the detector as a ISP-SM90-120.
Some control panels may identify the ISP-SM90-120 as a
GM570LSN.
11.1.
Function test
The LSNi/LSN control panel can trigger a function test in
conjunction with an installed ISN-GMX-S1 internal test
transmitter. The ISN-GMX-S1 is activated through the control
panel using a seismic test function. An alarm is activated if
the detector is working correctly (activation time <3s).
11.2.
Automatic self-test
The LSNi/LSN control panel can set the time interval
(hour/day/week) for automatic self-test. The control panel
identifies any unsuccessful self-test.
The detector must be fitted with a ISN-GMX-S1 internal test
transmitter.

Commissioning
1.
Initialize the LSNi/LSN bus
2.
Wait 60 seconds.
The detector is now operational.
3.
Verify the correct radius and material type have been
selected by the control panel.
Using a multimeter (Ri ≥ 20 kΩ) at terminal 1 (0 V) and TP
(Fig. 1, item D) to monitor for the analogue integration

Functional checks
Functional checks can be performed as follows:
•
With the cover removed, scratch the metal case of the
detector with a screw driver.
•
Activate the ISN-GMX-S1 internal test transmitter
through the control panel using a seismic test function.
•
Apply the required input to activate the GMXS5 external
test transmitter, if provided.
•
Simulate an attack on the protected space.
•
Carefully replace the cover and secure it in place.
