notification appliances are designed to meet the of NFPA The National Fire Alarm Code and UL Also check your local Authority Having Jurisdiction for other codes or standards may apply SpectrAlert S2475XXX Series Strobe and P2475XXX Series style can be installed in systems using 24 volt panels having DC or rectified FWR power supplies The models can also be installed systems requiring synchronization module MDL required or systems do not require synchronization no module required This manual shall be left with the owner user of this equipment Alarm System Considerations and Non Temporal Coded Signals American National Standards Institute and the National Fire Alarm require that all horns used for building evacuation installed after July 1996 must produce Temporal Coded Signals other than those used for evacuation purposes do not have to pro the Temporal Coded Signal Temporal coding is accomplished by inter a steady sound in the following manner Sec Sec Sec Sec Sec Sec Supply Considerations typically supply DC filtered voltage or FWR full wave rectified The system design engineer must calculate the number of units in a zone based on the type of panel supply Be certain the sum of the device currents do not exceed the current capability of the panel are based on using the device current found in the subsequent and must be the current specified for the type of panel power sup used Sizes designer must be sure that the last device on the circuit has sufficient to operate the device within its rated voltage When calculating voltage available to the last device it is necessary to consider the volt drop due to the resistance of the wire The thicker the wire the less voltage drop Generally for purposes of determining the wire size nec for the system it is best to consider all of the devices as the end of the supply circuit simulates case wire size resistance AWG solid AWG solid AWG solid AWG solid 8 ohms 1,000 ft 5 ohms 1,000 ft 3 ohms 1,000 ft 2 ohms 1,000
