Description
 
Supervised Facility Communication and Emergency Voice Evacuation Audio and Audio Strobe Power Boosters, UL Standard 1711 and UL Standard 864, 9th edition with 24VDC battery backup capabilities. Designed to provide for additional supervised audio power for live voice, pre-recorded messages or background music (BGM). Fully supervised patent pending circuitry is always in effect even during BGM. The SPB-80/4 also provides 4 Amps of 24 VDC Supervised and Synchronized Strobe Power.

The SPB-320, SPB-160 and the SPB-80/4 easily connects to the Wheelock SP40S or SP40/2. Multiple SPB-320, SPB-160 and SPB-80/4 Audio Boosters can be inter-connected to accommodate large installations with supervised audio power and also supervised and synchronized strobe power requirements.

The SPB-320 draws 2.4 watts of audio input power to properly operate and provide additional supervised audio output power. The SPB-160 and the SPB-80/4 draws 1.2 watts of audio input power to properly operate and provide additional supervised audio output power. A maximum of 5,280 watts of supervised audio power can be achieved. Additional strobe power can be obtained via a combination of SPB-80/4 or Wheelock Power Supplies Chargers.
