The SD500-ANM gives you the flexibility to add notification circuits wherever you need them. The SD500-ANM is a supervised addressable notification device that provides you with additional notification circuits on the IntelliKnight SLC loop. Up to 127 SD500-ANM modules can be used on an SLC loop. The SD500-ANM provides a reverse polarity Class A or Class B notification appliance circuit with an aux power input. Each SD500-ANM is provided power from a separate power supply and is controlled and supervised by the main panel. Power can be provided near the signaling appliance to reduce the wire gauge requirements or can come from a main power supply and be controlled separately by the individual notification modules. The SD500-ANM can produce all 16 of the notification patterns available on the FACP.
