Power consumption is 1.2 Watts. Audio Input Return.
Field Wiring Connections NOTE: The terminal blocks on the Audio Booster are removable. To remove a terminal block, pull the block straight up from the circuit board, as shown in Figure 3-4. Attach wires to the desired connections, then plug the terminal block back on the board being careful to match the pins. Figure 3-4 Removable Terminal Block 4.
Audio and Auxiliary Input Connections The audio input circuit (AUD IN) consists of either the power limited 25V or 70.7V circuit of the SP40/2 panel. The input uses a blocking capacitor for DC supervision. The audio return (AUD RET) can be used to link other SAFEPATH4 Audio Boosters to the host voice evacuation panel, additional speakers powered by the host panel, or connecting the host panels EOLR.
Audio and Strobe Output Circuit Connections NOTE: A UL Listed 10K Ohm EOLR shall be installed on both AUD1 and AUD2 outputs for supervision whether they are used or not. If the audio circuit is used, the UL Listed 10K Ohm EOLR shall be place on the last audio appliance on the circuit. Failure to do so will cause an open condition causing the TROUBLE LED D24 to turn on as well as the respective OPEN LED to light. NOTE: AUD1 and AUD2 are two separate 80 watt, Class B, power limited audio output circuits.
Expansion Output and Trouble Contact Connections The purpose of the Expansion Output (EXP OUT) is to provide a 24VDC at 0.5A supervised, power limited output when the Audio Booster audio output is operating. This allows additional Audio boosters to be connected by having the EXP OUT connect to the AUX IN of the next Audio Booster. The strobe input circuit on an SPB-80/4 will not cause the expansion output to energize.
CAUTION: Do not connect input voltage to any equipment until the field wiring has been tested, inspected and approved. 1. Check the integrity of all field wiring. Confirm that specified wiring is installed, and that there is continuity between required points (no open circuits), with no unwanted shorts to other conductors, chassis, or earth ground. a. Verify that the field wiring complies with the instructions of this manual and the detailed wiring diagram prepared for this installation. b.
CAUTION: The National Electric Code limits the maximum number of conductors that can be installed in conduit and wiring boxes depending on the size of the conduit, the volume of the boxes, and the gauge of the wire used. Make sure that wiring used for installation complies with the latest NEC, NFPA, Local, State, County or Province requirements.

Perform the following tests: Strobe Circuit Test (SPB-80/4 Only) 1. Switch SW4 to the CC position (depressed to the left). Short the STB IN terminals. Strobe Output Circuit should flash. Red LEDs D61 STB1 OUT and D62 STB2 OUT shall be lighted. Remove short. Audio Output Test 1. Play a digital message or use the built in microphone on the SP40/2 voice evacuation panel and test the audio output circuit(s). WARNING: ALL PROTECTIVE SIGNALING SYSTEMS REQUIRE PERIODIC TESTING.
Batteries of different capacities, age, or manufacturer shall not be used together. Battery Storage Batteries which are to be stored for an extended period of time should be given a supplement charge monthly. Batteries should never be stored in a discharged condition. The self-discharge rate of batteries is approximately 3% per month when the storage temperature is maintained at 20 degrees C (68 degrees F). The self-discharge rate will vary depending upon temperature.
Section 3-9 - AC Power and Battery Installation Procedures NOTE: Power limited and non-power limited wiring must be separated. 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 PROPERTY DAMAGE, SERIOUS INJURY, OR DEATH TO YOU AND/OR OTHERS. WARNING: OBSERVE CORRECT POLARITY REQUIREMENTS ON ALL CONNECTIONS. FAILURE TO DO SO MAY DAMAGE THE EQUIPMENT.
