Designed to provide 1 Year Warranty for additional supervised audio power for live voice, pre- System Activation: Audio recorded messages or background music (BGM). Fully supervised patent pending circuitry is always in effect even 70V or 25V input from the SP40S or SP40/2 during BGM.The SPB-80/4 also provides 4 Amps of 24 VDC 1 Volt input from SP4-RMX Supervised and Synchronized Strobe Power. System Activation: Strobe (SPB-80/4) •The SPB-320, SPB-160 and the SPB-80/4 easily connects 8 - 33VDC NAC input connected to the strobe input to the Wheelock SP40S or SP40/2. Multiple SPB-320,SPB- Power Supply&Batteries 160 and SPB-80/4 Audio Boosters can be inter-connected Fully supervised patent pending circuitry always in to accommodate large installations with supervised audio effect even during BGM power and also supervised and synchronized strobe power Power limited circuitry requirements. Class D amplifiers • Internal battery charger and power supply The SPB-320 draws 2.4 watts of audio input power to Required batteries fit inside the enclosure (sold properly operate and provide additional supervised audio separately) output power. The SPB-160 and the SPB-80/4 draws 1.2 SPB-320 requires four 12 VDC, 12 AH batteries watts of audio input power to properly operate and provide SPB-160 and SPB-80/4 require two 12 VDC, 12 AH additional supervised audio output power. A maximum of batteries 5,280 watts of supervised audio power can be achieved. Outputs: Additional strobe power can be obtained via a combination SPB-320 has four 80 watt speaker output circuits of SPB-80/4 or Wheelock Power Supplies/Chargers. SPB-160 has two 80 watt speaker output circuits • SPB-80/4 has one 80 watt speaker output circuit and two 2 amp strobe circuits (4 amps total) Applications Supervised Audio Speaker outputs: 70V or 25V field selectable (all boosters must be either 70 V or • Provides for additional supervised audio power for 25 V) large installations Expansion output(supervised, 24VDC at .5A in alarm • Provides for additional supervised and synchronizable condition) used for connecting multiple boosters strobe power for large installations DC output(unsupervised for optional splitter power). • Can be used in new construction as well Each speaker circuit (four for the SPB-320, two for the as in retrofit construction SPB-160, one for the SPB-80/4) can connect to speaker splitters 6
