Audio Boosters
Description
Features
SPB-320
320 Watt Supervised Audio Power
Booster (Four 80 watt circuits)
SPB-160
160 Watt Supervised Audio
Power Booster (Two 80 watt circuits)
SPB-80/4
80 Watt Supervised Audio
Power Booster with 4 Amps of
Supervised and Synchronizable
Strobe Power (Two 2 Amp circuits)
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.
