GENERAL DESCRIPTION
The SpectrAlert Advance low frequency series of notification appliances offers a range of low frequency sounder and low frequency sounder/strobe products for wall and ceiling applications. Studies have shown that low frequency audible devices that operate around 520Hz are more effective in waking individuals in sleeping areas. The sounder only version is designed for use in 12 or 24 volt,
DC or FWR (full wave rectified) systems. Sounder/Strobe versions are only to be used with 24 volt, DC or FWR systems. These products are electrically backward compatible with the previous generation of SpectrAlert notification appliances. The 2-wire products fit systems where a single NAC controls both sounder and strobe. The System Sensor MDL3 module may be used to provide synchronization.
Models are approved for wall and ceiling installations.
FIRE ALARM SYSTEM CONSIDERATIONS
The National Fire Alarm Code, NFPA 72, requires that all sounders, used for building evacuation produce temporal coded signals. Signals other than those used for evacuation purposes do not have to produce the temporal coded signal. The National Fire Alarm Code, NFPA 72, will require effective Jan. 1, 2014 that audible appliances installed in sleeping areas produce a low frequency alarm signal that shall be a square wave or provide equivalent awakening ability. System Sensor recommends spacing notification appliances in compliance with NFPA 72.
LOOP DESIGN AND WIRING
The system designer must make sure that the total current drawn by the devices on the loop does not exceed the current capability of the panel supply, and that the last device on the circuit is operated within its rated voltage. The current draw information for making these calculations can be found in the tables within this manual. For convenience and accuracy, use the voltage drop calculator on the System Sensor website (systemsensor.com/volt).
When calculating the voltage available to the last device, it is necessary to consider the voltage drop due to the resistance of the wire. The thicker the wire, the smaller the voltage drop. Wire resistance tables can be obtained from electrical handbooks. Note that if Class A wiring is installed, the wire length may be up to twice as long as it would be for circuits that are not fault tolerant.
NOTE: The total number of strobes on a single NAC must not exceed 40 for
24 volt applications or 12 for 12 volt applications. Loop resistance on a single
NAC should not exceed 120 ohms for 24 volt and 30 ohms for 12 volt systems.
NOTE: A shorting spring is provided between terminals 2 and 3 of the mounting plate to enable wiring checks after the system has been wired, but prior to installation of the final product. This spring will automatically disengage when the product is installed, to enable supervision of the final system.
Removal of a notification device will result in an open circuit indication on the NAC.

Please refer to insert for the Limitations of Fire Alarm Systems
THE LIMITATIONS OF LOW FREQUENCY HORN/STROBES
The sounder and/or strobe will not work without power. The sounder/strobe gets its power from the fire/security panel monitoring the alarm system. If power is cut off for any reason, the sounder/strobe will not provide the desired audio or visual warning.
The sounder may not be heard. The loudness of the sounder meets (or exceeds) current Underwriters Laboratories’ standards. Studies have shown that the low frequency sounder (520Hz) is more effective at waking individuals in sleeping spaces, especially individuals that may have recently used drugs or drinking alcoholic beverages. The sounder may not be heard if it is placed on a different floor from the person in hazard or if placed too far away to be heard over the ambient noise such as traffic, air conditioners, machinery or music appliances that may prevent alert persons from hearing the alarm.
The low frequency sounder may not be heard by persons who are hearing impaired.
NOTE: Strobes must be powered continuously for sounder operation.
WARNING
The signal strobe may not be seen. The electronic visual warning signal uses an extremely reliable xenon flash tube. It flashes at least once every second. The strobe must not be installed in direct sunlight or areas of high light intensity (over 60 foot candles) where the visual flash might be disregarded or not seen. The strobe may not be seen by the visually impaired.
The signal strobe may cause seizures. Individuals who have positive photoic response to visual stimuli with seizures, such as persons with epilepsy, should avoid prolonged exposure to environments in which strobe signals, including this strobe, are activated.
The signal strobe cannot operate from coded power supplies. Coded power supplies produce interrupted power. The strobe must have an uninterrupted source of power in order to operate correctly. System Sensor recommends that the sounder and signal strobe always be used in combination so that the risks from any of the above limitations are minimized.
