Bosch Security Systems Seismic Detectors Application Guide I-200153-1

5 Planning
5.1 General Application
It is essential to plan each installation to ensure the best protection but also for the most reliable
performance from the detectors. In the sections below, are guides in what conditions to avoid. In
addition to this, it is essential that the correct installation practices are followed and only Bosch Se-
curity Systems accessories, detailed in section 3 are used to compliment the system.
5.2 General Planning Guidelines
• The ISN-SM-xx range of seismic detectors operate at maximum efficiency on steel or concrete
sur
faces. Correct operation and performance of the detectors on other surfaces cannot be
guaranteed.
• Verify the layout drawing against the detection parameters of the detectors and accessories t
o
ens
ure compliance.
• If drawings are not available, perform a physical measure and then verify the detecti
on
par
ameters of the detectors and accessories to ensure compliance.
• For new build concrete vaults, ensure coordination between with the builder to ensure t
he
ac
cessories are installed as per the instructions. Don’t forget the cable access conduit prior to
the concrete being poured.
• If the vault is existing or a new build, perform a visible inspection to identify any weaknesses i
n
t
he construction that may impair the transmission of the acoustic signals.
• Ensure that all equipment planned to be used is compatible and that performance and/or
approval are not compromised, (refer to section 4.4)
• Do not install the detectors on block type brickwork as the mortar joints will impair the acoustic
signals. If in doubt, seek clarification of the structure.
• Do not install the detector on materials other than concrete or steel, as the correct operatio
n
and per
formance of the detectors cannot be guaranteed.
• Check that the ISN-SM-xx seismic detectors have a direct connection to the protected surfac
e
and t
hat all section paint has been removed, drill template removed, mounting plate installed (if
required).
• Determine the ambient noise levels for the protected areas prior to completing the installation.
(Refer to sections 6 & 7 for additional information).
• Determine the storage height of the equipment within the protected space prior to final
installation, this may avoid accidental alarms due to contact from shelving and can also assist
with access for maintenance/service purposes.
• Determine the environmental conditions for the protected space and ensure that they are withi
n
al
lowed tolerances.
• For vaults, ensure that all fascia of the vault have at least one detector installed.
• Ensure that all doors have a detector installed and that any lock protection system is adequat
e
f
or the purpose.
• Determine if any real attacks can be performed after the installation has been completed as
this may assist with the handover of the system.
• Establish the ambient temperature of the protected space and the temperature levels should b
e
s
et at +/-10° C above this level. ISN-SM-50 has a fixed temperature surveillance and the ISN-
SM-80 & ISN-SM-90 have selectable temperature surveillance levels.
• Refer to sections 4.3 & 4.4 for additional information.
5.3 Planning limitations
Although the Bosch Security Systems ISN-SM-xx series of seismic detectors are designed to pro-
vide a high level of immunity against unwanted alarm sources, it is essential that certain precau-
tions are observed.
