INSTALLATION AND MAINTENANCE INSTRUCTIONS SP2 Series Speaker/Strobes for Protective Signaling Systems Ohio Avenue, St. Charles, Illinois 60174 FAX: 630-377-6495 to 18 AWG (3.31 to 0.82 mm2) inches (101 mm) Strobe Range: DC or Full-Wave Rectified use with the following models: SP2R2415, SP2R2430, SP2R241575, SP2R2475, SP2R24110, SP2W2430, SP2W241575, SP2W2475, SP2W24110 Patent Nos. 5,593,569; 5.914,665; 5,850,178; 5,598,139; 6,049,446; 6,127,935 Speaker Terminals: Size: Dimensions: 8.25 x 4.9 Input: Range: Range: 32 to 120 (0 to 49 for Strobes: Do not exceed 1) 16-33 Voltage range limit, 2) Maximum number of 70 strobe lights when connecting MDL Sync module with a maximum line impedance of 4 Ohms per loop and 3) Maximum line impedance as required the fire alarm control manufacturer. Rate: Output: Models with 1575 are listed at 15 candela UL1971 but will provide 75 candela on (straight ahead). with 15, 30, 75 or 110 are rated for candela. to 30 volts, (21 to 30 volts with MDL flash per second volts or 70.7 volts (nominal) 4000 Hz 1 1 and 2 Watts S4048 (Speaker/Strobe), S5512 (Strobe) This manual shall be left with the owner/user of equipment.

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.

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.
