Praesideo 3.5 | Installation and User Instructions | EN60849: 1998
Requirement
i
All messages shall be clear, short, unambiguous
and as far as practicable, pre-planned.
Where pre-recorded messages are used they shall
be held in a non-volatile form, preferably in a solid-
state store, and be continuously monitored for
availability.
The system design shall make it inherently
impossible for an external source to corrupt or
derange the store or its contents.
NOTE - On grounds of reliability, it is preferable not
to use storage media depending on mechanical
devices.
j
The language(s) used shall be specified by the
purchaser.
k
The system shall be capable of being divided into
emergency loudspeaker zones if required by the
evacuation procedure. Such zones need not be the
same as other zones, for example emergency
detection zones or non-emergency loudspeaker
zones.
l
In determining loudspeaker zones, the following
criteria shall apply:
1
the intelligibility of messages broadcast in one
zone shall not be reduced below the
requirement of 5. 1 by the broadcasting of
messages in other zones or from more than one
source.
2
no emergency detection zone shall contain
more than one emergency loudspeaker zone.
For non-emergency use, a loudspeaker zone
may be subdivided.
m A secondary power source shall be available
(see 5.6).
EN60849 - 4.2 Responsible person
Requirement
The person or body, having control of the premises
shall nominate a "responsible person", identified by
name or job title, who shall be responsible for ensuring
that the system is properly maintained and repaired so
as to continue to operate as specified.
EN60849 - 4.3 Priorities
EN60849 - 4.3. 1 Classification of priorities
Requirement
It is necessary to decide upon an order of priority for
the message distribution based upon:
a
Any automatic programmed response.
b
The perceived risk to occupants, which may require
manual override of the programmed response.
Events shall be given a level of priority according to
their urgency. The following primary levels are
recommended but there may be advantages in adding
further subgroups, depending on the operational
strategies of the site:
a
Evacuate - potentially life-threatening situation
needing immediate evacuation.
b
Alert - dangerous situation nearby requiring
warning of pending evacuation.
c
Non-emergency - operational messages, e.g.
system test, etc.
