Emergency Test

Broadly speaking, emergency lighting can be implemented in one of two solutions; Central Battery / Static Inverter system or Self Contained Fittings.

By utilizing the DALI protocol, we are able to meet the Statutory Requirements (BS5266-1:2005) for emergency test and monitoring in both configurations - without the need to wire a separate network infrastructure.

In a Central Battery System, the lighting control system would automatically at the scheduled time drive all emergency lights on to their maximum load, then instruct the static inverter to simulate a mains failure for the specified test duration. Any lamp or ballast failures will be reported (as they would at any other time). Some Central Battery units even allow for the monitoring of advanced measurements such as battery voltage, phase currents, temperatures, etc. The lighting control system would schedule the testing of Self Contained Emergency fittings so that adjacent luminaries are tested on different days. This reduces the risk of all emergency fittings having a low battery level at the same time. The test results are reported for each fitting via the DALI bus and include details such as battery level, inverter status, test duration, etc.

A KNX sun controller is able to accurately determine the sun’s brightness, position in the sky (based on the geographical coordinates, time of year and time of day) and decide on the correct height for the blinds so as to optimize natural light, reduce glare and minimize solar gain.


  • Continuous real-time monitoring of emergency luminaries
  • Automated test regimes
  • Support for non-DALI luminaries through current sensing or local photocells (limited reporting)
  • Historic record of all test results
  • Central Battery or Self Contained Emergency fittings monitored and tested via the same system
  • Support for Fluorescent and LED emergency luminaries


  • Single solution for Emergency Test and Monitoring and standard Lighting Control
  • Simplified wiring to all luminaries
