Functional Checks - Bosch ISN-SM-80 Guide D'installation

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.
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 14.
8. Programming
8.1. Application setting (Fig. 1, item K)
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.
Select the material type for the protected space and the required detec-
tion radius by selecting the DIP switch options as follows:
Operating
radius (r)
Mode Fixed
Steel ---
LWS ---
Concrete 4m
There are 3 settings selectable via the DIP switch (Fig. 1, item K), to
enable the USER MODE selectable settings through the ISN-SMS-W7
SensTool Software. DIP switches 1 & 2 must be in the ON position to
establish communications between the PC and the detector.
8.2. Sensitivity (Fig. 6, terminal 7)
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. The factory setting is Active low, Active
high is selectable through the ISN-SMS-W7 SensTool Software.
Sensitivity is reduced to 12.5% of the original setting for the duration of
the remote signal. A potential application is the prevention of alarm
triggering where loud functional noises prevail.
8.3. Test input (Fig. 6, terminal 4)
The ISN-GMX-S1internal test transmitter (Fig. 1, item J) is activated by
the application of a low signal into the test input terminal. If the detector
is functioning correctly, the detector will trigger an alarm (trigger time
<3s).
The factory setting is Active low. Active high is selectable through the
ISN-SMS-W7 SensTool Software.
Active low = 0 V applied to activate.
Active high = 0 V removed to activate.
9. LED display
The red LED (Fig. 1, item E) pulses during initialisation. In the event of an
alarm, the LED illuminates for approximately 2.5 seconds. This LED is
only visible when the cover of the detector is removed.
10. Commissioning
1. Apply the supply voltage.
The LED (Fig. 1, item E) pulses for 10 seconds.
2. Leave the detector for a further 20 seconds.
The detector is now operational.
3. Verify the correct radius and material type have been selected
by the DIP switches or the ISN-SMS-W7 SensTool Software.
If SensTool is not available, then using a multimeter (Ri ≥ 20 kΩ) at
terminal 1 (0 V) and at the test point (Fig. 1, item D) to monitor for the
analogue integration signal:
Quiescent level

Alarm threshold (w/o load)
4. Check for interference using the SensTool > Analyse option.
The Digital Filter setting in the Settings tab may assist in

reducing inherent interference. For additional information,
please refer to the ISN-SMS-W7 SensTool Software and the
associated manual.

10.1. Functional checks

Functional checks can be performed as follows
•
With the cover removed, scratch the metal case of the detector with
a screw driver until the LED (Fig. 1, item E) confirms an alarm.
•
Apply the required input to terminal 4 to activate the ISN-GMX-
S1internal test transmitter, if provided.
•
Simulate an attack on the protected space.
•
Carefully replace the cover and secure it in place.
11. Service
The function of the detector and its mounting should be checked at least
once a year, as follows:
•
Functionally test the detector as detailed in section 10.1.
•
Verify the settings of the detector by the DIP switches or by the ISN-
SMS-W7 SensTool Software.
•
Check the mounting of the detector to ensure that the detector is
securely attached.
•
Check that there is a direct connection between the detector and
the mounting surface. Paint, varnish, dirt, silicone or similar materi-
als will impede the acoustics.
Refer to local approvals for guidance on this matter.
12. Modular vaults
The following principles must be strictly observed when using seismic
detectors on modular vaults made from steel or concrete.
•
Thickness from 100 to 400mm
•
Width up to 1000mm
•
Length up to 6500mm

Corner joints between walls seamlessly welded Always 1 detector on
Strict compliance with the following principles is vital when using
seismic detectors on modular vaults made from steel and concrete:
1. One detector for a maximum of 5 wall modules. The detector must
be mounted on the middle module.
2. In addition to being bolted together, all of the joints between the
modules must be welded every 400 − 500mm with a 30 − 40mm
seam.
3. Corner joints between wall modules must be seamlessly welded if
the coverage area is to extend beyond the corners.
4. In the case of wall modules equipped with detectors, the
immediately adjoining floor and/or ceiling modules can be included
in the coverage area if the corresponding butt joints are seamlessly
welded.
5. Where building vaults use modules of varying thickness, the butt
joints must be seamlessly welded.
6. Avoid mounting detectors on modules to which guide rails for
cassette transport lifts, ventilators or other mechanical equipment
are attached.
7. Always equip modules which have a pay-in/withdrawal slot with a
detector. The detector can monitor the adjacent modules.
8. All doors must be equipped with a detector.
