Load on Loop: A Voltage Range: 12VDC/FWR (8.0 to 17.5V); or 24VDC/FWR (16.0 to 33V) Ohio Avenue, St. Charles, Illinois 60174 Fax: 630.377.6495 Strobes are con- to sync module, input voltage at 12V: 8.5 to at 24V to 33VDC/FWR Slave Input (3) V V Temperature: to 120 (0 to 49 UL1971, ULC S525, ULC S526 1) For maximum number of strobes and/or maximum line impedance, refer to the voltage drop calculator found at Systemsensor.com; and 2) Maximum impedance as required by the fire alarm control manufacturer. 3) 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 synchronized to all other by interconnecting the input and output terminals modules. SoUnDeR on/off oveR 2-WiReS USinG MoDULe contRoL the current source to the horn control input. If a zone output used for the source, you must use an EOL on the horn control input see Figure 1. multiple modules are
