Abstract
A method for testing an emergency lighting product connected to a network includes creating, at a network control device, a first test schedule for causing the emergency lighting product to perform a test, where the test is scheduled to be performed by the emergency lighting product based on a signal received from the network control device after a first time period. The method further includes creating, at the emergency lighting product, a second test schedule for causing the emergency lighting product to perform the test after a second time period, where the second time period is longer than the first time period and begins at the same time as the first time period, and determining, by the emergency lighting product after the second time period, that the signal has not been received from the network control device, and performing, by the emergency lighting product, the test.
