Emergency lighting systems; Previous inspectors have disconnected the power supply timing down the usage over a defined time period. They only seem to replace the battery if it fails, is this correct?
No. We prefer to maintain your emergency lighting system by obtaining a post voltage and recording it. We then disconnect the power supply and identify load amperage and the number of remote heads and equipment that is operated by this electrical circuit. Over an elapsed time of 30 minutes we will record the voltage remaining on the battery, connect the power supply and identify the charge amperage. If the battery is still operational but the voltage readings identify the battery is near failure – we will replace the battery.
