Manual test (S)
In this case the power supply is
manuallycut to emergency light luminaires. During monthly function
tests, the length of the test is a maximum of 25% of the expected
lighting time. During annual tests the equipment should undergo a full
decharge test to check battery capacity.
Test status is found by
visual checking of the charge diode and the light source at the same
time that testing takes place. Tests and repairs should be logged with
their status.
Self-test (ST)
Emergency light
luminaires take control of the tests themselves and carry these out at
the necessary times and intervals as dictated by regulations.
Test
status is found with a visual check of one or more two-coloured diodes
in the luminaire. Visual control should take place on a monthly basis.
Tests and repairs should be logged with their status.
Addressable (DALI)
DALI
is an addressable, standardised control protocol designed for lighting.
DALI has now also been expanded to manage emergency lighting. In
addressable emergency equipment the tests are programmed from a central
unit. The system is divided into test zones and all test status and any
repairs are automatically recorded in the. central unit. Today, there
are various types of software and control modules which manage DALI
emergency lighting protocols. DALI Emergency lighting can be connected
to other DALI controls in accordance with certain regulations.
Glamox
has decided that DALI is the control protocol that we will rely on. See
also page 426 for further information about DALI control panels.
