How does the automatic self-test work?

Explanation about emergency lighting fixtures with automatic self-test

The automatic self-test on emergency lighting automatically checks if everything is working properly, without the user having to do it themselves. This keeps the emergency lighting reliable and greatly reduces the chance of problems, which is important for a safe environment.

Self-test

Self-test luminaires perform a self-test when they are first powered on. After 24 hours of charging, a full 3-hour self-test is conducted. Initial tests are randomly generated. They are then carried out in accordance with standard requirements (every +/- 4 weeks for a function test and every +/- 52 weeks for a duration test).

A two-color LED indicator is incorporated into all self-test products. This LED indicator is clearly visible for visual inspection. The LED indicator shows solid green or flashes green when conditions are normal and flashes red when there is a fault. See the tables below.

Duration test

A duration test simulates a power outage. It also checks the operation of the emergency light source from the battery supply for the nominal duration of the module. The LED indicator flashes rapidly green during the duration of the test. If a fault occurs during the duration test, the LED indicator will flash red. In that case, always contact Taurac or an authorized electrical installer to rectify the fault. The battery must be fully charged before a duration test can be started.

Function test

A function test is a 2-minute test that simulates a power outage and checks the operation of the emergency light source via the battery supply. The local indicator LED flashes slowly green while the 2-minute function test is ongoing. If a fault occurs during a function test, the local indicator LED will flash red. In that case, always contact Taurac or an authorized electrical installer to rectify the fault.
