Emergency Lighting
Maintaining a Scheme
All emergency lighting schemes have
to comply with European legislation
and regulations
Emergency lighting design schemes are used to ensure that the installation will
meet required lighting levels and protect the occupants with escape route, open
area and high risk task lighting.
Once the scheme is installed and commissioned, it is essential that the
luminaires are properly maintained and ready to perform in the event of an
emergency. To make sure installed emergency products are always fit for
purpose, regular testing has to be conducted by the building operator and
a record of testing kept.
Testing Emergency Lighting Products
Emergency lighting products have to be tested regularly to meet the requirements of
European law. As shown above, the standard EN50172 stipulates the precise nature
and frequency of the testing.
A full record sheet needs to be maintained for each emergency fitting. These
sheets have to be available for inspection by the authorities at any time.
Failure to provide full test records can result in legal action and closure of the
building. In the event of an emergency, if the emergency lighting is defective, the
insurance policy for the building may be invalidated and the building operator
could face a heavy fine or imprisonment.
Recent changes to the laws governing emergency lighting have shifted the
responsibility for the risk assessment, maintenance and testing to the building operator.
This testing can be tedious, costly and time consuming.
Making Life Easy
To help building operators maintain a fully functional emergency lighting scheme
that meets the full raft of legal requirements, Thorn offers three testing solutions:
•Central addressable testing
•Automatic self testing
•Basic manual testing
Frequency

Purpose
Daily
Check all LED charging indicators
are in operation
Ensure the batteries are being
charged
Monthly
Conduct a functional test for all
emergency luminaires
Check that the luminaire will operate
in the emergency mode
Annually
Perform a full 3 hour duration test for
all emergency luminaires
Confirm that the battery capacity will
operate the product for the required 3
hour time period
E3TX emergency gear offers SelfTest and Addessable Test functionality in
a single fitting. E3TX luminaires operate as SelfTest when standalone and
become Addressable when connected to either a Sensa 2 or Sensa 3
lighting control system.

Central Addressable Testing
Every emergency luminaire is
connected to an intelligent local
controller that automatically conducts
all the necessary tests and stores the
full results in one central location.
Sensa TP2
Sensa TP2 is a central addressable
testing system that provides fully
automatic monitoring, testing
and fault logging for up to 240
emergency fittings. This system
delivers a range of benefits:
•Ultimate convenience for
emergency lighting testing.
•All results automatically stored
in one location. No need for
paperwork.
•Fault logging function identifies
each luminaire, the location and
the precise nature of the fault.
•All tests conducted at a convenient
time, depending on the usage of
the application
•Group testing staggers the testing
to minimise the risk of depleted
batteries.
•Simple to install and commission.
•Intelligent luminaires linked to the
local controller using standard
1.5mm
