Chapter 4: Installation 4.2.4 Installing Audio and Auxiliary Input Connections The audio input circuit (AUD IN) consists of either the power limited 1V, 25V, or 70.7V circuit of the SP40S panel. The input uses a blocking capacitor for DC supervision. The audio return (AUD RET) can be used to link other Series SPB Audio Boosters to the host voice evacuation panel, additional speakers powered by the host panel, or connecting the host panels 1/2W 1/2W EOLR.
Chapter 4: Installation 4.2.5 Installing Strobe Input Connections (SPB-80/4) The strobe input circuit (STB IN) consists of either a power limited 8-33VDC regulated NAC circuit input or a contact closure input. The input uses reverse polarity for supervision. The strobe return (STB RET) can be used to link other Series SPB Audio booster strobe NAC circuits to the host voice evacuation panel, additional strobes powered by the host panel, or connecting the host panels 1/2W EOLR.
Chapter 4: Installation NOTE: STB1 and STB2 are two separate 2-Amp, Class B, power-limited strobe regulated NAC circuits. Do not wire STB1 and STB2 together. Figure 4-12 shows the audio and strobe output connections as they are on the SPB-80/4. Notice that there are two strobe outputs.
Chapter 4: Installation Audio Out Figure 4-8 Audio Output (SPB-160 and SPB-320) Connections 1. Connect Audio Appliance circuit to Audio Output (AUD OUT) connection(s). Figures 4-12 and Figure 4-13 are enlarged diagrams of the referred areas. The Audio Output(s) is supervised. A UL Listed 10K Ohm, 1/2W EOLR is required at the end of the circuit for proper supervision. 2. For the SPB-80/4, select the proper output voltage (25V or 70V) using the Audio Output Select Jumper J1B and J3.
Chapter 4: Installation Expansion Out and Trouble Contacts Figure 4-9 Alarm and Trouble Connections The Trouble relay changes state whenever a trouble condition occurs on the Audio Booster circuit board and when the TROUBLE LED D73 lights. As shown in Figure 4-14, connecting to the common terminal (C) and the normally open terminal (NO) would prevent current flow through the relay contacts in the normal operating condition. A trouble condition causes the relay to switch states, allowing current to flow.
Chapter 4: Installation Power and DC Connections Figure 4-10 Power and Battery Connections NOTE: DC OUT is a 27VDC at 0.5A output for powering splitter modules only. BATTERY terminals are used to connect the backup batteries to the panel for recharging and backup power. The UL approved battery connection is 24VDC up to 33Ah. The enclosure can accommodate up to 12Ah. See Figure 4-15. CAUTION: Do not connect input voltage to any equipment until the field wiring has been tested, inspected, and approved. 1.
Chapter 4: Installation WARNING: Two different sources of power may be connected to this unit. Disconnect both sources of power before servicing. Failure to disconnect both power sources before servicing could result in serious injury, or death to you and/or others. 4.3 Two-Wire Audio and Four-Wire Audio Modes The Series SPB Audio Booster can be connected to the SP40S in four different modes. Refer to Table 4-1 for a description of these modes.
Chapter 4: Installation Table 4-1. Series SPB Wiring Modes Wiring Mode When To Use Effects Section Two-Wire Mode with AC Loss reported on Main Trouble Contacts This mode is generally used when no secondary operations (BGM, Telephone Paging, etc.) are being used on the SP40S and the least amount of connection wires is desirable. If one Audio Booster has any trouble, then all Audio Boosters connected to the SP40S lose secondary operations. 4.2.1.

Chapter 4: Installation 4.6.2 Checkout Procedure Connect AC power, then connect batteries. NOTE: When the AC power source is applied to the panel, the battery voltage check circuitry is activated. If batteries are not connected within 20 seconds, the panel trouble circuit activates. The battery voltage check circuitry re-checks for batteries every two minutes. If the batteries are installed during the two-minute period, the panel remains in trouble until the next re-check.
Chapter 4: Installation 4.8 Battery Care and Backup Battery Calculations 4.8.1 Caring for Sealed Lead Acid Batteries Sealed lead acid batteries are designed to operate in standby service for approximately five years. This is based upon a normal service condition where there is an ambient temperature of 20 degrees C (68 degrees F) and batteries are completely discharged once every three months.
Chapter 4: Installation 4.8.3 Calculating Backup Battery Requirements A Worksheet for assisting in calculating batteries is available in Chapter 11. Due to the current drain on the battery, the maximum battery size for the Series SPB Audio Booster SPB-80/4 and SPB-160 is 33Ah. For the SPB-320, each SPB-160 has its own backup batteries. The enclosure can accommodate up to 12Ah. Larger batteries may necessitate a separate battery box. It is necessary to calculate the current draw for batteries requirement.
Chapter 4: Installation 4.9 Installing AC Power and Batteries NOTE: Power-limited and non-power limited wiring must be separated. WARNING: Two different sources of power may be connected to this unit (SPB-80/4 and SPB-160); for the SPB-320, each module uses two different sources of power. Disconnect both sources of power before servicing. Failure to disconnect both power sources before servicing could result in serious injury or death to you and/or others.
Chapter 4: Installation 4.9.2.B Installing Batteries on the SPB-320 NOTE: Batteries are not supplied with this panel and must be purchased separately. The SPB-320 requires four 12V batteries UL rated up to 33Ah. The enclosure can accommodate up to 12Ah batteries. Two are wired in series to each SPB-160 module. Run the battery wiring across the top of each power supply (SPBPS) and down the right side of the power supplies to the batteries.
