recommended practices for the speak 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 for DC supervision SpectrAlert SP2 series strobe can be installed in systems 24 volt panels having DC or full wave rectified FWR supplies The strobes can also be installed in appli requiring synchronization MDL required or appli that do not require synchronization no module 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 Having Jurisdiction for other codes or standards 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 in 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 cir has sufficient voltage to operate the device within its voltage When calculating the voltage available to the device it is necessary to consider the voltage drop due the resistance of the wire The thicker the wire the less voltage drop Generally for purposes of determining wire size necessary for the system it is best to consid all of the devices as on the end of the supply simulates 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 length outgoing return The voltage at the end of loop is 0.050 amps per device 10 devices 3 ft 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 manu specifications as well as SpectrAlert operating range to determine acceptable voltage drop If class wiring is installed the wire length may up to 4 times the single wire length in this calculation wiring must be installed in compliance with the Electrical Code NEC and applicable local codes well as special requirements of the authority having using the proper wire size This also includes applicable 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 electrical supervision 1 Electrical connections FROM NEXT OR EOL FROM SUPPLY NEXT OR EOL Supply power for strobe must be continuous for operation See Figure 2 as an example of how to select a 1 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

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 CURRENT

reverse the strobe module insert screwdriver as shown Fig 3 to unlock snap While pushing in the screwdriv pull back on the strobe module Hinge the strobe mod disengage the Locking Rib and lift the module away the mounting plate Turn the module so that it is down from its original position re insert the mod into the mounting plate be sure to insert the Locking into the slot and press the module into the mounting The strobe module will make a when it has into place Turn the entire assembly so that the word is right side up The unit can now be mounted mount back box speaker strobe can be flush mounted on a 4 4 back box Fig 4 as follows Select the appropriate pair of diagonally opposite holes in the speaker grille that will be used to the speaker strobe to the back box Do not insert mounting
