Fire Alarm Test 121

This is a very cool system installed in an elementary school. The main panel is a simplex 4002. However, rather than adding more nacs to the 4002 they for whatever reason opted to install a 4009 booster power supply below the 4002. As a result, half of the building does continuous and the other half does code 3 which is kind of cool sounding.
