Single Gang Double Gang 4 Octagon This manual shall be left with the owner user of this equipment DESCRIPTION SpectrAlert Advance low frequency series of notification appliances offers range of low frequency sounder and low frequency sounder strobe products wall and ceiling applications Studies have shown that low frequency audi devices that operate around 520Hz are more effective in waking individuals sleeping areas The sounder only version is designed for use in 12 or 24 volt or FWR full wave rectified systems Sounder Strobe versions are only be used with 24 volt DC or FWR systems These products are electrically compatible with the previous generation of SpectrAlert notification The 2 wire products fit systems where a single NAC controls both and strobe The System Sensor MDL3 module may be used to provide are approved for wall and ceiling installations ALARM SYSTEM CONSIDERATIONS National Fire Alarm Code NFPA 72 requires that all sounders used for evacuation produce temporal coded signals Signals other than those for evacuation purposes do not have to produce the temporal coded sig The National Fire Alarm Code NFPA 72 will require effective Jan 1 2014 audible appliances installed in sleeping areas produce a low frequency signal that shall be a square wave or provide equivalent awakening abil System Sensor recommends spacing notification appliances in compliance NFPA 72 Ohio Avenue St Charles Illinois 60174 FAX 630 377 6495 to 120 0 to 49 to 93 Non condensing flash per second 12VDC FWR or regulated 24VDC FWR 24VDC FWR to 17.5V 12V nominal or 16 to

the loop does not exceed the current capability of the panel supply that the last device on the circuit is operated within its rated voltage The draw information for making these calculations can be found in the within this manual For convenience and accuracy use the voltage drop on the System Sensor website systemsensor com volt calculating the voltage available to the last device it is necessary to the voltage drop due to the resistance of the wire The thicker the the smaller the voltage drop Wire resistance tables can be obtained electrical handbooks Note that if Class A wiring is installed the wire may be up to twice as long as it would be for circuits that are not tolerant The total number of strobes on a single NAC must not exceed 40 for volt applications or 12 for 12 volt applications Loop resistance on a single should not exceed 120 ohms for 24 volt and 30 ohms for 12 volt systems A shorting spring is provided between terminals 2 and 3 of the mount plate to enable wiring checks after the system has been wired but prior installation of the final product This spring will automatically disengage the product is installed to enable supervision of the final system of a notification device will result in an open circuit indication on NAC 3 WALL MOUNT LF SOUNDER mounting plate 4 WALL MOUNT LF SOUNDER STROBE PRODUCT are approved for Wall Ceiling installations 5 WALL MOUNT LF SOUNDER WITH MOUNT BACK BOX MOUNTING INDOOR WALL OR CEILING PRODUCTS Attach mounting plate to junction box as shown in Figures 3 and 4 The plate is compatible with 4 inch square double gang and 4 inch oc junction boxes 2 wire products may be used with a single gang box Connect field wiring to terminals as shown in Figures 1 If the product is not to be installed at this point use the paint cover to contamination of the mounting plate For indoor models only To attach product to mounting plate remove the paint cover then hook on the product housing into the grooves on mounting plate Then swing product into position to engage the pins on the product with terminals on the mounting plate Make sure that the tabs on the back the product housing fully engage with the mounting plate Secure product by tightening the single mounting screw in the front the product housing For tamper resistance the standard captivated screw may be replaced with the enclosed Torx screw MOUNT BACK BOX MOUNTING The surface mount back box may be secured directly to the wall or ceil Grounding bracket provided if needed The wall mount box must be mounted with the up arrow pointing up Threaded knockout holes are provided for the sides of the box for inch inch conduit adapter Knockout plugs in the back of the box can used for inch and inch rear entry To remove the inch knockout we recommend you use a flat head and place the blade along the inner edge and work your way the knockout as you strike the screwdriver as shown in Figure To remove the inch knockout place the blade of the screwdriver the edge and work your way around the knockout as you strike the as shown in Figure 8 V500 and V700 wiremold raceways are also provided Use V500 for low applications and V700 for high profile applications To remove the wire mold knockout turn pliers up as shown in Figure 9 Attach the mounting plate to the surface mount back box using the four screws as shown in Figure 5 or 6 Follow steps 2 6 of the
