The strobe lights and bell are powered by emergency lighting panel 1 via pressure switch PS-1 (figure 10, item 1).
The fire suppression alarm system has two horns. One horn is mounted in the engine room and the other in
AMS 1. The horns are powered by the emergency generator battery charger circuit via pressure switch PS-1A
(figure 10, item 2). As seen in figure 10, the use of two separate power sources provides greater assurance that
personnel in the hold level will be warned if the FM-200 fire suppression system is activated.
