Automatic Self Testing

Each self test emergency luminaire

contains an intelligent diagnostic

processor that automatically performs

the testing and uses the integrated

bi-colour LED indicator to show the

test results.

SelfTest fittings provide simple and

reliable standalone automatic testing

solutions. The building operative only

needs to walk around the building

once a month and check the status of

the LED indicators. The overall result

must be recorded in a central log

book, with details of any failures.

SelfTest fittings offer a variety

of benefits:

•Easy to install, with no additional

cabling and automatic

self-commissioning

•The building owner only needs to

walk round the building once per

month and record the result

•Faster than average recharge time

for emergency batteries (around

10 - 15 hours, compared to 24

hours for Manual Test fittings)

•3 hours operation, to facilitate

re-entry following an evacuation

•Bi-colour LED (red and green) to

provide clear status indication

•Boost starting technology gives

higher lumen output during most

critical phase to ensure greater

visibility of potential danger

•Cathode heating during

emergency operation prolongs

emergency lamp life

•Intelligent processor learns to test

while the building is unoccupied,

reducing potential risk

Applications

SelfTest is an ideal testing solution

for small applications or building

refurbishments.

Key examples include small shops,

offices and public buildings.

Basic Manual Testing

This kind of emergency luminaire relies on intensive human intervention to

comply with the stringent testing regulations.

Every month a competent individual must walk around the site and manually switch

the fittings into the emergency test mode. This will perform a functional test, after

which an individual record sheet must be completed and safely stored. The same

process must be carried out for the 3 hour duration test once every year.

In this case, the LED indicator only shows whether the battery is being charged.

Any further fault requires manual examination of the fitting. Combined with the

fact that a competent individual has to walk around the site every month, basic

manual testing luminaires incur high whole life costs due to expensive labour

charges for testing and maintenance.

Applications

Basic manual test is suitable for budget-driven installations where the whole

life costs are not considered

Sensa 3 TSC

For larger applications with more than 240 emergency fittings, Sensa 3 TSC

allows the building operator to monitor and manage the emergency lighting

scheme from a standard computer. Sensa 3 TSC enables a standard computer

to communicate with local controllers using the installed computer network.

Applications

Sensa 3 TSC has the ability to control an infinite number of emergency

luminaires. In applications such as university accommodation blocks, hotels,

large offices, hospitals and air ports, Sensa 3 TSC will deliver significant time

and cost savings in terms of maintenance and inspection.
