Abstract

A method for controlling a fixture (122) includes receiving a message from a controller (102), determining whether the message includes an address associated with the fixture (122), retrieving an identifier of the controller (102) from the message responsive to determining that the message includes an address not associated with the fixture (122), determining whether the fixture (122) includes a fixture channel (204) controlled by the controller (102), and resetting a timer (203) associated with the fixture channel (204) controlled by the controller (102) responsive to determining that the fixture (122) includes the fixture channel (204) controlled by the controller (102).
