Fire Protection Association NFPA has pub standards and recommended practices for the described in this manual As a result the must be familiar with these requirements as well all local codes and special requirements of the authority jurisdiction SpectrAlert SP2 series speakers can be operated with amplifiers having an output voltage of either volts or 70.7 volts speakers operate at any one of four input power levels output sound level is selected at the time of installa but can be changed if necessary speaker is also equipped with a capacitive input to al for DC supervision SpectrAlert SP2 series strobe can be installed in using 24 volt panels having DC or full wave FWR power supplies The strobes can also be in applications requiring synchronization MDL or no module required do not SpectrAlert SP2 series speaker strobes are designed to the requirements of most agencies governing these including NFPA ADA The National Fire Alarm UL CSFM MEA Also check with your local Au Having Jurisdiction for other codes or standards may apply Supply Considerations For Strobes typically supply DC filtered voltage or FWR full Strobe Range DC or Full Wave Rectified to 30 volts 21 to 30 with MDL module flash per second Rate Output Models with 1575 are listed at 15 candela UL1971 but will provide 75 candela axis straight ahead with 15 30 75 or 110 are rated for candela rectified voltage The system design engineer must the number of units used in a zone based on the of panel supply Be certain the sum of all the device do not exceed the current capability of the panel are based on using the device current found Table 2 and must be the current specified for the type of power supply used Sizes designer must be sure that the last device on the circuit sufficient voltage to operate the device within its rated When calculating the voltage available to the last it is necessary to consider the voltage drop due to resistance of the wire The thicker the wire the less the drop Generally for purposes of determining the size necessary for the system it is best to consider all the devices as on the end of the supply circuit case wire size resistance AWG solid Approximately 8 ohms 1,000 ft AWG solid Approximately 5 ohms 1,000 ft AWG solid Approximately 3 ohms 1,000 ft AWG solid Approximately 2 ohms 1,000 ft Assume you have 10 devices on a zone and each 50 mA average and 2000 Ft of 14 AWG wiring to length outgoing return The voltage at the end of loop is 0.050 amps per device x 10 devices x 3 ohms ft x 2000 ft 3 volts drop same number of devices using 12 AWG wire will pro only 2 volts drop The same devices using 18 AWG will produce 8 volts drop Consult your panel specifications as well as SpectrAlert oper voltage range to determine acceptable voltage drop Manuals Online wiring must be installed in compliance with the Na Electrical Code NEC and applicable local codes as as special requirements of the authority having juris using the proper wire size This also includes all NFPA Standards ANSI UL 1480 UL 1971 and 760 Connect the speaker strobe as shown in Figure 1 Keep mind that even though the speaker and strobe are a mechanical unit they are electrically independent require separate power sources Do NOT loop electrical wiring under terminal Wires connecting the device to the control must be broken at the device terminal con in order to maintain
