ZAURA Starter Operation
When the Master is operating, ZAURA Starters respond to commands from the Master. If
the room’s light switch is set to the OFF position, all lamps will be turned OFF irrespec-
tive of Master commands. When the light switch is set to the ON position, all lamps will
initially be turned ON. After communication is reestablished between the Master and its
associated ZAURA Starters, Master control of the ZAURA Starters resumes.
In the absence of a Master, or when the Master contains either no battery or a low battery,
the ZAURA starters perform traditional ON/OFF behavior based on the position of the
light switch.
When commanded by its Master to ignite or extinguish a lamp, the ZAURA Starter will
perform a limited number of attempts. This behavior prevents excessive ignite and extin-
guish strikes on lamps near the end of their life cycles. The ZAURA Starter will again
attempt to ignite and extinguish a lamp if the lamps are cycled by either the Master using
ON/OFF commands or by manual power cycling the lamps OFF for one minute, then ON
using the light switch.
