Clause / Requirement
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].
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 intensi-
ties 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.
14. 1 0 Audible indication
14. 1 0.2 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 con-
templates some s.s.c.i.e. being installed in normally occupied
areas (such as a security room). The selection of an appropri-
ate sound level can be controlled by national requirements.
14. 1 2.3 Frequency response of s.s.c.i.e.

Compliance
The Bosch Security Systems development department respon-
sible 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 matu-
rity 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.
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 sys-
tem is in the voice alarm condition (i.e. until the voice alarm con-
dition 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 indi-
cation stays on until either the rotary knob of the network con-
troller 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 indi-
vidual faults after which the oldest faults are deleted when new
faults occur.
The display of the Network Controller complies with the legibil-
ity demands of this clause.
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 accord-
ing to the second option. The selection depends on the back-
ground noise on the location where Praesideo is installed or by
national requirements.
The frequency response requirements of ISO7240-16, clause
14. 1 2.3 are less stringent than required by EN54-16, clause
13. 1 2.3.
The Praesideo sound paths are within the specified limits of this
clause.
