Terminal Block 1
TB1
AC IN AC sensing Input Connection Factory connection senses proper AC Voltage input. Low AC or no AC input
will light the AC LED and cause a trouble condition.
Terminal Block 2
AUD IN Audio Input 25V or 70.7V power limited audio input. Blocking capacitor for DC
Supervision. Power consumption is 1.2 Watts.
AUD RET Audio Return Audio Input Return. Used to continue Audio Circuit from the voice
evacuation panel, connecting additional audio boosters, or voice evacuation
panel’s EOLR.
AUX IN Auxiliary Input 8 to 33VDC (10mA) NAC power limited source or contact closure input.
Used in the Four Wire mode. Applying an alarm input restores audio booster
to full power from the power saver mode when panel is in battery backup
mode. Reverse Polarity.
TB2
AUX RET Auxiliary Return 8-33VDC (10mA) NAC power limited source (only) Auxiliary input return.
Used to connect to additional audio boosters through the voice evacuation
panel.
Terminal Block 3
STB IN Strobe Input (SPB-80/4 Only) Power limited 8 to 33VDC (10mA) NAC power limited source or contact
closure input. Initiates Strobe Outputs on the SPB-80/4 only. Reverse
Polarity.
TB3
STB RET Strobe Return (SPB-80/4 Only) Strobe Input Return - Used to continue strobe input circuit, connecting
additional strobe input circuits from audio boosters, Strobe appliances or
voice evacuation panel’s EOLR.
Terminal Block 4
DC IN DC Input Factory wired 24VDC Input from power supply (SAPS)
DC OUT DC Output 24VDC at 0.5A, non-power limited used for splitter power only.
TB4
BATTERY Battery 24VDC Battery connection for battery charging and battery backup.
Terminal Block 5
AUD2 OUT Audio 2 Output (SPB-160 Only) Audio Output #2 - Provides 25V or 70.7V, power limited audio output at 80
watts. Supervised using a UL Listed 10K Ohm EOLR.

watts. Supervised using a UL Listed 10K Ohm EOLR.
STB2 OUT Strobe 2 Output (SPB-80/4 Only) 24VDC at 2.0A NAC power limited Supervised using a UL Listed 10K Ohm
EOLR.
TB5
STB1 OUT Strobe 1 Output (SPB-80/4 Only) 24VDC at 2.0A NAC power limited Supervised using a UL Listed 10K Ohm
EOLR.
Terminal Block 6
EXP OUT Expansion Out 24VDC at 0.5A power limited circuit energized when a signal is applied to
AUX IN or Strobe In. Reverse polarity Supervised using a UL Listed 10K
Ohm EOLR.
TB6
TRB Trouble Form C relay rated at 24VDC at 1.0A. Used for external trouble reporting.
