4.0 Specifications
This subsection provides specifications for the L-810 obstruction light fixtures.
4.1 Lamp-Out Relay Operation
120 VAC input power to the dual L-810 fixture energizes a relay and the normally operating lamp #1. If lamp #1 fails, the relay
is de-energized causing the 120 VAC to be switched to the backup lamp #2. At the same time, 120 VAC power is also switched
to the alarm terminal, which can be used to activate a user-supplied alarm.
