equipment Description National 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 SP2C series ceiling mount speaker strobe be operated with distribution amplifiers having an out voltage of either 25 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 SP2C series ceiling mount strobe can be in systems using 24 volt panels having DC or full rectified FWR power supplies The strobes can also installed in applications requiring synchronization required or applications that do not require no module required SpectrAlert SP2C series ceiling mount speaker strobes designed to meet the requirements of most agencies these devices including NFPA The National Alarm Code UL CSFM MEA Also check with your Authority Having Jurisdiction for other codes or stan that may apply Supply Considerations For Strobes typically supply DC filtered voltage or FWR full 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 Manuals Online 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 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 1 Electrical connections 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 electrical supervision 2 Voltage and Power Selection ol lo ol ls2J FROM NEXT OR EOL

as shown See Figure 2 as an example of how to select a 1 4 Watt when a 25 volt amplifier is being used Notice that header SW1 has two shunts One shunt is used to either 25 or 70.7 volts input The other shunt is to select input power of 1 4 1 2 1 or 2 Watts 1 lists the UL reverberant and anechoic output levels for each power tap on the SP2C series ceil mount speaker strobes levels exceeding 130 rated signal voltage can the speaker Consequently an incorrect tap con may cause speaker damage This means that if a tap is selected when a 70.7V amplifier is being used damage may result Therefore be sure to select proper taps for the amplifier voltage input power combination being used SP2C series ceiling mount speaker strobe can be flush on a 4 x 4 x 2 1 8 back box Use two 8 32 x 1 pan head
