The strobe lights and bell are powered by 120V emergency lighting panel No. 1 via pressure switch PS-1 (figure 6, 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 6, item 2). As
illustrated in figure 6, 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.
