Commissioning

Using a small metal plate to protect the surface, hit the metal plate
with a firm blow with a small/medium hammer
tector as this will cause damage to the device.
For the ISN-SM-50, ISN-SM-80 & ISN-SM-90 detectors, remove the
GMXD7 anti-drill foil, if fitted, or remove the hold off jumper.
The ISN-SM-50 has a fixed temperature range lower -15° C to +85°
C. The ISN-SM-80 & ISN-SM-90 have default settings the same as
the ISN-SM-50 but are adjustable by 1° C to lower and upper limits
of -40°C and 85 °C. If these limits are exceeded then an alarm is in-
dicated. (not practical to perform on site)
For all detectors place the hand the hand held test tool adjacent to
the detector and press the test button.

Staged commissioning
It is possible to commission seismic detectors using a power source and a multi-meter. This option
may be useful for staged commissioning or when permanent supplies or commissioning tools are not
yet available.
7.3.1
Staged commissioning procedure
1. Power up the device, observing the correct polarity and leave for 30 seconds.
The internal LED will pulse for 10 seconds to confirm that the correct power is applied. The
LED is not available on the ISN-SM-30 version.
2. Verify that the correct detection radius and material type are selected via the DIP switches or
use the SensTool, if available to select.
3. Use a multi-meter at terminal 1 (0 V) and at the test point, which is a gold coloured solder pad,
just to the left hand side of the terminal strip.
The following voltages will determine the status of the detector.

Test method
•
Quiescent level = circa 0 to 0.3v DC
•
Detection of the integration signal will increase the voltage to = 1v DC, this voltage will
continue to increase, in direct proportion to the strength and/or duration of the integration
signal. The integration alarm can be generated by use of the hand held test tool or by
scratching the base plate of the detector with a screwdriver.
•
Activating the GMXS1 or GMXS5 will increase the voltage to around 2.7v DC.
The LED beside the test point on the detector illuminates as visual confirmation for all
detectors except the ISN-SM-30.
•
Activating the shock alarm will increase the voltage to around 2.7v DC when the required
impact is detected.
The LED beside the test point on the detector illuminates as visual confirmation but
recording the voltage and providing the required impact may be difficult to achieve.
•
Alarm threshold (w/o load) = 3v DC. Note that this 3v DC reading only reflects the
integration alarm and does not depict a drill alarm, temperature alarm and/or a shock
alarm.
