HEALTH AND SAFETY
When lead acid and nickel cadmium wet cells
are being charged they give off a potentially explosive
mixture of oxygen and hydrogen. Always ensure adequate ventilation
when installing equipment in confined areas and display
signs warning against smoking and naked flames.

MODE OF OPERATION
- Non-Maintained: Load is not normally energised but
upon mains failure it is energised via the battery. This
is AC and DC output.
- Maintained: Load is energised at all material times
via lighting transformer and upon mains failure via the
battery. This is AC and DC output respectively.
- Floating: Load is supplied from permanently connected
battery/charger. This is DC output.
LOAD
The battery systems should not be fully
loaded and so as to ensure maximum battery life we would
recommend the design load of the system to be up to 80%
of the maximum rating.
CABLE SIZES
Volt drop in cable runs must be calculated
before deciding on the systems voltage. Fire protected cables
must be used, we would recommend that you consult the appropriate
experts if in doubt.
BATTERY VOLTAGES
24, 50 and 110v are the nominal voltages
generally available and utilised. 240v is appropriate on
large installations where volt drop and current levels need
to be kept within certain limits.
BATTERY TYPES
- Valve Regulated Lead
Acid
State of the art sealed lead acid technology using a design
where the acid is immobilised in a sponge like material.
During the life of the battery there is no loss through
gassing as cells are completely sealed.
Service life of 10 years.
- Flat Plate Lead Acid
Low internal resistance, excellent regulation, easy to
check and reasonable neglect tolerance.
Service life 12-15 years.
- Nickel Cadmium
Extremely robust, will tolerate arduous operating conditions
and both electrical and mechanical abuse. Easy to check,
can be left discharged without damage.
Service life up to 25 years.
- Plante Lead Acid
High performance cells, exceptionally reliable trouble
free service when well maintained. Easy to check, low
maintenance the cells retain 100% capacity throughout
their life and provide excellent performance at high or
low levels of discharge.
Service life up to 25 years
CENTRAL POWER SUPPLY SYSTEMS
(CENTRAL BATTERY SYSTEMS)
Central Power Supply Systems (Central Battery
Systems) provide the emergency power to a number of connected
(slave) luminaires. The Central Power Supply Systems (Central
Battery Systems) should be connected to the luminaires via
a fire protected cable as specified in BS5266.
Due to the complex nature of Central Power
Supply Installations (Central Battery Installations) it
is strongly recommended that the complete installation is
reviewed by a competent person, fully trained in such installations.
Central Power Supply Systems are deemed
to comply with the requirements of the Fire Precautions
(Workplace) Regulations 1997 if:
- They are designed and manufactured in accordance with
the appropriate product standard prEN 50171.
or
- Checked and validated by a competent person as fit
for purpose and installed in accordance with the requirements
of BS5266.
ICEL provides a scheme of product registration
for Central Power Supply Systems (Central Battery Systems),
ICEL 1009, assuring users that products carrying the ICEL
registration mark, produced by the registered organisation,
have been designed in accordance with the requirements of
prEN50171, batteries are correctly specified to achieve
the full rated discharge for their design life and that
the equipment has been manufactured in a facility operating
a suitable scheme of quality assurance.
SYSTEM DESIGN
The following are guidelines only but would
normally reflect the basics of a well designed system. Your
major requirement is to activate the emergency lighting
in either local or complete mains failure.
- A non-maintained system would utilise sub-circuit monitors,
this ensures via a series of relays, that all emergency
lighting luminaires would be activated wherever
failure may be.
- A maintained system is quite simply energised at all
material times therefore the luminaires are illuminated
irrespective of their condition.
- A maintained system with hold off relays allows you
to illuminate certain local areas of the building upon
mains failure whilst the remainder operates under mains
healthy conditions. In a complete mains failure all luminaires
would be active in the emergency mode.
- A maintained AC/DC system with conversion modules housed
within chosen luminaires. The luminaire then operates
in mains healthy and to a reduced level of brightness
in emergency mode.
- A static inverter runs conventional mains fittings at
full brightness under mains healthy or emergency operation
