Self Test & Central Test Systems
Automatic Testing Systems to test emergency lighting products.
Two types of automatic testing are available for testing emergency lighting products.
Most of the self contained fittings supplied by Smart Systems are also available with a self test option. This function is initiated by an integral microprocessor which interrupts the power and typically tests the fitting briefly each month, and an annual full duration test. Reporting is provided by coloured led’s led s and /or intermittent buzzers to indicate faults.
The advantages of this type of testing are that no additional wiring is required and the cost difference over the standard unit is relatively small.
The disadvantages are that even though the tests are carried out in line with the relative standards an individual still has to attend each luminaire and record the resultant test. In addition as the tests are normally carried out randomly, disruption is possible in premises with sleeping accommodation.
As the name suggests the emergency fittings are connected, usually by a 2 core cable to a central control panel which initiates the tests and stores the results. The luminaires will either feature a self test interface in each fitting or be DALI compatible to provide the communication with the control panel. Programming the panel provides the flexibility to test the fittings in zones and at times to suit the operation of the building.
The advantages with the centralized system are that the results of the tests are stored in the control panel removing the need for individual testing and inspecting the luminaires, therefore saving considerable time and money on larger sites .As each luminaire has a unique address location it is a simple job to trace any faults.
Additional cabling and control panels costs are prohibitive for smaller premises
