Clause / Requirement Compliance Signature
If the building is to be evacuated following
primary power failure, a secondary power
supply shall be provided. This shall be
capable of operating the system in the
emergency mode for a period equal to
twice the evacuation time determined by
the appropriate authority for the building.
In any event, the secondary power supply
shall be capable of powering the system for
a minimum of 30 min. Power consumption data is
available in various Plena
equipment data sheets. With this
information the necessary back
up capacity can be calculated,
Responsibility of the installer.
If the building is not to be evacuated
following failure of the principal power
supply, the secondary power supply shall
be capable of operating the system for at
least 24 h, or 6 h if an emergency generator
is available, and then powering the system
in emergency mode for a minimum of 30
min. If a building remains unoccupied for
several days, provision should be made to
ensure that the voice alarm system is
capable of operation in emergency mode
for 30 min. when the building is re-
occupied. See above. Responsibility of the
installer.
Non-emergency functions within the
system, such as background music, shall
not operate from the secondary power
supply if this will reduce the capacity for
emergency operation. Responsibility of the installer by
connecting the BGM source to
the primary power supply. From
release 1.1 onwards the BGM will
be deactivated.
If batteries are used as a secondary power
supply they shall be of the secondary type,
complete with automatic charging facilities.
Where lead-acid batteries are used they
shall be of the valve-regulated type unless
otherwise specified, and the charging
system shall incorporate charging current
compensation for changes in the ambient
temperature, where this is necessary to
achieve the specified battery life. Responsibility of the installer.
Batteries shall be used in accordance with
the manufacturer's recommendations in
order to achieve their specified life, which
shall be not less than four years. The end
of life shall be taken as the time when
deterioration to less than 80% of the rated
ampere-hour capacity (at the one-hour
rate) has occurred. Responsibility of the installer.
