signaling strobe are intended be connected to the alarm indicating circuit of a UL fire alarm control panel Both are compatible with DC supervision The electronic sounder can be connected either 12 or 24 VDC panels Models SS2415ADA SS24110ADA SS241575ADA and combina models incorporating these strobes require 24 volt and MASS121575ADA require 12 volt pan Panels may have full wave rectified unfiltered power The strobes produce one flash per second nomi with continuous nominal voltage applied Models MA12 24D is suitable for outdoor applications 35 cid 176 to C when it is used with a WBB

Mount See Fig 10 and 13 Flush Mount See Fig 12 Sounder Strobe combination mounting one of eight sounds can be selected on the electronic as indicated in Table 2 The sound selected deter the maximum current and sound power output per See Table 1 for these values Sounder Strobe Operation may be applications where it is desirable to drive the and strobe as independent devices The System MASS12 24ADA series sounder strobes are easily for this capability The terminal connection for application is shown in Figure 6 Independent strobe in a coded system requires a separate uncoded supply for the strobe General head screws are used to attach each device or of devices to the electrical outlet box head screws are used to attach accessories to the Refer to Figures 3,4,5 and 6 for wiring methods Do not loop wires under the terminal screw Wires the device to the panel must be broken Surface Mount See Fig 9 Semi Flush Mount See Fig 10 and 13 mounting requires the use of the deep box Part or equivalent Determine which of the two device will be used to attach the device to the box Mount flush plate to the sounder using the other two holes two 1 inch phillips head screws and two square Strobe mounting Surface Mount See Fig 8 Semi Flush Mount See Fig 11 procedures must conform to all applicable and the requirements of the authority having The rated output of the sounder is specified at 10 It cannot be assumed that the output will the NFPA standard of 15 dB over ambient at all locations within a room Additional may be needed to ensure sound output complies with NFPA requirements Limitations of Sounder Strobes Sounder and or Strobe will not work without power The sounder gets its power from the fire security panel monitoring the alarm If power is cut off for any reason the sounder strobe will not pro the desired audio or visual warning Sounder may not be heard The loudness of the sounder meets or current Underwriters Laboratories standards However the may not alert a sound sleeper or one who has recently used drugs has been drinking alcoholic beverages The Sounder may not be heard it is placed on a different floor from the person in hazard or if placed too away to be heard over the ambient noise such as traffic air condition machinery or music appliances that may prevent alert persons from the alarm The Sounder may not be heard by persons who are impaired Signal Strobe may not be seen The electronic visual warning signal flashes at least once every three seconds meets or exceeds current Un Laboratories standard 1971 and uses an extremely reliable xe Manuals Online flash tube The visual warning signal is suitable for direct viewing and be installed within an area where it can be seen by building occu The strobe must not be installed in direct sunlight or areas of high intensity over 60 foot candles where the visual flash might be disre or not seen The strobe may not be seen by the visually im signal strobe may cause seizures Individuals who have a positive response to visual stimuli with seizures such as epileptics should prolonged exposure to environments in which strobe signals in this strobe are activated Sensor recommends that the Multi Alert Sounder and Signal always be used in combination so that the risks from any of the limitations are minimized signal strobe cannot operate from coded power supplies Coded supplies produce interrupted power The strobe must have an unin source of dc power in order to operate correctly
