Clause / Requirement Compliance Signature
14 Design requirements
14.1 General requirements and manufacturer's
declarations
14.1.2 In order to assist the process of design inspection,
the manufacturer shall declare in writing that
a the design has been carried out in accordance with a
quality management system that incorporates a set of
rules for the design of all elements of the s.s.c.i.e.
[e.g. ISO 9001].
The Bosch Security Systems development department
responsible for development / maintenance of the
Praesideo system works according its own development
process, Standard Development Process or SDP, which
is created using the CMMI model. The SDP implements
all process areas at maturity level 2 of the CMMI model,
and some process areas at maturity level 3 of the CMMI
model.
Rules for the design of all elements of the Praesideo
system can be found in the SDP repository. In the SDP
repository all process descriptions, process
implementation documents, templates, guidelines, etc. of
the development processes can be found.
The SDP repository is a version control system.
Bosch Security Systems is ISO9001 certified.
14.8.6 Mandatory indications on an alphanumeric display
shall be legible for the lesser of 1 h or the duration of the
standby power source, following the display of a new
indication of a functional condition, at 0,8 m distance in
ambient light intensities from 5 lx to 500 lx and at any
angle from the normal to the plane of the display up to
• 22,5° when viewed from each side;
• 15° when viewed from above and below.
Following the lesser of 1 h or the duration of the standby
power source, the indications shall be legible at 100 lx to
500 lx at the above distance and angles. It shall be
possible to re-establish the legibility at 5 lx to 100 lx by
means of a manual operation at access level 1.
If the Praesideo system enters the voice alarm condition
the display of the network controller will automatically
show the 'Emergency' menu. This indication stays on as
long as the system is in the voice alarm condition (i.e.
until the voice alarm condition is reset).
If the Praesideo system enters the fault warning
condition the display of the network controller will
automatically show the 'Faults' menu with the current
number of active faults. This indication stays on until
either the rotary knob of the network controller is used to
navigate through the menu, or the system enters the
voice alarm condition. The 'Faults' menu will always be
present in the Network Controller menu. Individual faults
are present in this 'Faults' menu until they are reset or
until they are overwritten by newer faults The menu can
show up to 200 individual faults after which the oldest
faults are deleted when new faults occur.
The display of the Network Controller complies with the
legibility demands of this clause.
14.10 Audible indication
14.10.2 The minimum sound level, measured under
anechoic conditions, at a distance of 1 m with any
access door on the s.s.c.i.e. closed, shall be either
• 60 dBA for voice-alarm indications and 50 dBA
for fault-warning indications, or
• 85 dBA for voice-alarm indications and 70 dBA
for fault-warning indications.
NOTE The allowance for two sets of audible indications
contemplates some s.s.c.i.e. being installed in normally
occupied areas (such as a security room). The selection
of an appropriate sound level can be controlled by
national requirements.
The installer must connect the buzzer that is provided
with Praesideo and complies with the sound levels
according to the first option, or use a different buzzer
with sound levels according to the second option. The
selection depends on the background noise on the
location where Praesideo is installed or by national
requirements.
14.12.3 Frequency response of s.s.c.i.e. The frequency response requirements of ISO7240-16,
clause 14.12.3 are less stringent than required by EN54-
16, clause 13.12.3.
The Praesideo sound paths are within the specified limits
of this clause.
