Section 5: Applications 5.1 Controlling Four NACs With One Input and Selective Silence NOTE: The Relay Module is required only for this application with the power supply set as Master. If the power supply is set as Slave, the Relay Module is not required. In Slave mode, selective silence (horn mute) is provided by the FACP through the sync input. In this application, the power supply has been set as a master with synchronized outputs and selective silence (see SW1 switch settings in following illustration). All four HPF24S output circuits, which are shown as NACs (Notification Appliance Circuits), can be controlled from one input such as an addressable control module as illustrated in Figure 5.1. The control module can be powered from the HPF24S auxiliary 24 VDC power output (TB4, Terminals 9 & 10) and supervised by an EOL relay. An addressable relay module, programmed as an alarm output and a silenceable point, can be used as a selective silence input. 28 HPF24S Series Power Supplies - P/N 52751:D3 5/11/2010
