Average current draw of NAC Slave input when connected as in figure 3 DeScRiption MDL3 Module is designed to work with the SpectrAlert Advance series notification appliances to provide a means of synchronizing the temporal horns and chimes synchronizing the one second flash timing of the and silencing the horns and chimes of the horn strobe and chime combination over a two wire circuit while leaving the strobes active is intended to connect to UL or ULC listed FACP or its NAC accessories a boost module etc This manual shall be left with the owner user of this equipment confiGURation MDL3 module has the capability of connecting two Style Y Class B or one Style Z Class A circuit zone output s from the panel are connected to the zone input s of the module and the zone output s from the MDL3 module are connected the notification loop s Supervision is accomplished in the module by a connection between the zone input and the zone output of each of the zone circuits connected to the normal end of line device The FACP EOL device through the MDL3 module When either or both outputs the module are wired to the SpectrAlert Advance products the horns or and strobes in both zones will be synchronized 1 Input 2 Input Control In input powers the MDL3 module This input must voltage present from the FACP before anything work This also supplies voltage to Zone 1 out input only supplies voltage to Zone 2 output If Zone 1 input is not powered the notification attached to the Zone 2 output will be out of input enables the horns on the SpectrAlert notification appliances Voltage present horns are enabled No voltage present means are disabled to Master MDL3 Module slave out A maxi of 11 slave MDL3 modules can be connected to a MDL3 Out to Slave MDL3 slave in Slave In to slave MDL3 from NAC A dedicated NAC be used for slaving purposes MDL3 module can be configured so that more than two zones can synchronized by the interconnection of the slave input and output Figures 1 2 and 3 SpectRaLeRt aDvance hoRnS chiMeS anD StRobeS module can power two 3 amp circuits wired in class B or one circuit powered as Class A module will synchronize 2 zones modules can be added and may be

for the source you must use an EOL on the horn control input see Figure 1 multiple modules are used the horn control circuits can be wired parallel If wired in parallel and a zone output is used from panel use EOL on the last module for supervision it supervised Horn Control wiring must be contained within com enclosure of FACP Out Slave In wiring must be contained within either the common of modules or enclosures within 20 feet of each other with wiring conduit Reverse wiring will cause this input to malfunction Zone 1 input is not powered or fails during alarm the notification devices to the Zone 2 output will not be synchronized Ground fault on a module two wire loop can be indicated at the panel if the control panel is capable of ground fault detection on the supply to the module and meets UL 864 9th Edition ground fault in requirements for initiating device circuits The installer must verify capability 1 NAC slave wiring must be dedicated to sync purposes No devices be
