9.2. Pre-amplifier Panel PP-025B Connection • You can install the Chime Unit in the Pre-amplifier Panel. (Refer to p. 16.) • Input 1-A jack is located on both the front and rear panels. When both jacks are simultaneously used, the broadcast from the front panel is allowed to go through. • Input 1 takes precedence over Inputs 2 and 3, while Input 2 takes precedence over Input 3. Connect a BGM player to Input 3, and the microphone and chime to Input 1 or 2 depending on the degree of their importance.
9.3. Power Amplifier Panel Connection • Use the same output line voltage when connecting power amplifier panels for parallel operation. You can connect up to three power amplifier panels of the same kind in parallel. Important: Make connection so that the total of speaker rated input power is less than 1 kW for a group of five consecutive speaker lines (i.e. lines 1-5, 6-10, etc.). • Do not use the 4 Ωoutput terminal for the rack PA system. • Refer to p.
9.4. Emergency Power Supply Panel DS-029B Connection 9.4.1. Battery connection Internal Ni-Cd batteries are optional. Depending upon the output and number of power amplifier panels to use, and the number of connected emergency remote control units, select the proper type of battery. After installing the selected battery in the DS-029B, make connections. For battery selection, refer to p. 8 "About the Emergency Power Supply".
9.4.3. About the operation of the Emergency Power Supply Panel DS-029B When the AC power is supplied and the Emergency Activation terminal is not shorted (standby status).... Current flows in coils D and E, and contact points d and e are as shown below. 24 VDC is not sent to REMOTE (left) or outputs 1-4.
When the emergency function is operated while the AC power is cut off (power failure).... Current flows in Coil F in the Junction Panel JP-0410 and contact point f switches, thereby causing the 24 VDC power output from REMOTE (left) of the Emergency Power Supply Panel DS-029B to return to the DS029B's REMOTE (right). As a result, the current flows in Coils B and C and contact points b and c switch as shown below, transmitting 24 VDC to outputs 1-4.
9.4.4. Connections Connections of the Emergency Power Supply Panel DS-029B are classified into four methods a, b, c, and d depending on the composition selected in the section "About the Emergency Supply Panel" on p. 8. Because the operation and control sections are fundamental to the emergency broadcast system, any failure in their operation will disable the function of the entire system.
Connection method b for the DS-029B In this method, two batteries (one DS-029B unit) are connected to supply power to the operation/control sections and power amplifier panel separately.
Connection method c for the DS-029B In this method, three or more batteries (multiple DS-029B connection) are connected to supply power to the operation/control section and power amplifier panel separately.
Connection method d for the DS-029B In this method, three or more batteries (multiple DS-029B connection) are connected. A single DS-029B unit contains two batteries: one to supply power to the operation/control section and one to supply power to the power amplifier panel.
9.4.5. Connecting a single emergency power supply panel to power amplifiers The figure below shows the method of connecting the Emergency Power Supply Panel DS-029B to the power amplifier panel. Refer to the figure when expanding power amplifier panels or designing the power amplifier rack. • Only a single power amplifier panel (up to 120 W) can be connected per output terminal of the emergency power supply panel.
9.5. Junction Panel JP-0410 Connection 9.5.1. Connecting the Junction Panel's rear-mounted terminal block 1. 24V IN/OUT terminals • The power capacity of the JP-0410's built-in power supply is 2 A. Use the 24V IN/OUT terminals when the power capacity is insufficient because of an increase in the number of zones or remote controls. (Refer to p. 35.) • The junction panel is shorted between IN and OUT terminals using a jumper wire at the factory.
9.5.2. Connecting the AC power supply of the Junction Panel JP-0410 • The Junction Panel JP-0410 supplies the AC power to each component mounted in the rack. • AC power is always supplied to the UNSWITCHED AC outlets. Be sure to connect the Emergency Power Supply Panel to the UNSWITCHED outlet to keep its internal batteries fully charged. Make sure that the DC Power Supply Panels AD-011 and AD-031B are also connected to the UNSWITCHED outlet.
9.6. DC Power Supply Panel Connection 9.6.1. When the DC power supply panel is not required (i.e. when you can do with the junction panel's internal power supply).... The power capacity of the Junction Panel's (JP-0410) internal power supply is 2 A in maximum output current. Note the total current of connected components and external equipment. If their total current exceeds 2 A, the power supply must be expanded.
9.6.2. When expanding the power supply for external equipment Let us assume that one expansion power supply is added to the system solely to cover the shortage of power to be supplied to external equipment as the result of connecting many external equipment or mounting many components in the rack. Note: Remove the jumper wire placed between the 24V IN and OUT terminals of the terminal block located on the rear panel of the Junction Panel JP-0410.
9.6.4. Connection between DC power supply panel and Expansion Operation Panel EP-029 Make connections using the optional expansion power cable YR-931. Note the polarity when connecting. The red cord is for 24 VDC (+), while the black cord is for 24 VDC (–). YR-931 EP-EP cord Integrated Control Panel EP-0510 Use this cord to disconnect the power supply. Supplied with EP-029.
9.6.5. Connection between DC power supply panel and Expansion Junction Panel JP-039 Use the optional expansion power cable YR-931 for connection. Note the polarity when connecting. The red cord is for 24 VDC (+), while the black cord is for 24 VDC (–). YR-931 JP-JP cord Junction Panel JP-0410 Use this cord to disconnect power.
10. SETTING OF THE INTEGRATED CONTROL PANEL EP-0510 Use switches SW1-SW4 on the EP-0510's control circuit board for setting. ON 12345678 SW1 ON ON ON 12345678 12345678 12345678 SW2 SW3 SW4 Set the following items using the switches SW1-SW4. • [Warning Announcement Interlock] or [Warning Announcement Non-Interlock] mode (SW4-1) Use SW4-1 switch to set either mode.
• Evacuation Announcement interval (SW4-4 through SW4-8) Time intervals can be set for 30 seconds to 15 minutes 30 seconds in 30 seconds units. ON SW4 4 5 6 7 8 ON 8 minutes 4 minutes 2 minutes 1 minute 30 seconds OFF 0 0 0 0 0 1 2 3 4 5 6 7 8 SW4 Evacuation Announcement interval • All-zone announcement interval (SW2-3 through SW2-8) Time intervals can be set for "OFF", "0 second" or "30 seconds to 15 minutes 30 seconds" in 30 seconds units.
• Main Rack BGM broadcast (SW1-1 and SW1-2) Set equipment that can initiate Main Rack BGM. Both switches are set to OFF at the factory so as to allow the Main Rack BGM to be played from the [Main rack system and all emergency remote control units].
11. EXPANSION PANEL ADDRESS SETTING 11.1. Expansion Operation Panel EP-029 When your system contains the 10-Zone Expansion Operation Panel EP-029-10 or 20-Zone Expansion Operation Panel EP-029-20, the address number needs to be assigned to each expansion unit. • Use consecutive numbers starting with 0 to set the address.
12. CONNECTING THE RACK-MOUNTED COMPONENTS TO EXTERNAL LINES 12.1. Names of the Front-Mounted Terminal of the Junction Panel JP-0410 12.2. AC Power Supply Connections The power supply circuit of an emergency broadcast system must be a dedicated circuit, and the circuit breaker after a branch point must be marked with the indication of the dedicated power supply.
12.3. Speaker Connections Connect speaker cables to terminals R,N, and C, as shown below. (The R wire may be omitted when no attenuator is used.) When Expansion Junction Panel JP-039 is additionally used, make connections in like manner. Notes • The maximum connectable speaker wattage per line is 200 W. When exceeding 200 W, divide the line into two or more groups. • Connect speaker cables so that the total of rated inputs of every five speaker lines (1-5, 6-10, etc.) is less than 1 kW.
12.4. Connections to the Automatic Fire Alarm Systems By connecting the emergency PA system to an automatic fire alarm system, voice alarms can be automatically provided as soon as the PA system receives a fire signal from a fire detector. It must be seen to that the floor signal lines (EL) are connected to the junction panel terminals of their corresponding floors. Because fire confirmation signals (EF) are also important to automatic broadcast, connect their cables properly.
13. CONNECTION INSPECTION 13.1. Inspection of Connections and Wiring • After all connections are completed, inspect the connections and wiring again before turning on the AC breaker of Junction Panel JP-0410. • Ensure that cables are correctly connected between components. Also, check external wiring for connection errors and wiring omissions. 13.2. Adjustment and Measurement of Power Circuitry 13.2.1.
13.3. Speaker Line Adjustment and Measurement 13.3.1. Speaker line impedance measurement (using impedance meter) Measure the impedance of each speaker line, then measure the total impedance of all lines. Record the planned impedance and measured impedance for future maintenance and inspection. If the planned impedance is notably different from the total impedance, inspect individual lines again to find and remove the cause. Impedance of arbitrary wattage can be calculated using the formula below.
13.3.2. Speaker line insulation resistance measurement (Measuring instrument: Megger) Measure between the ground and the cable for each line. Do not measure between cables, as this can damage both the speaker and matching transformer. It is recommended that wiring be performed so that the following resistance values are obtained.
13.4. Speaker Sound Pressure Level Measurement [Measuring instrument: Sound level meter (A weighting network characteristics)] Measure the output sound pressure level at a 1 meter distance from the center of the installed speaker when the voice alarm second signal is sounding at the rated output. Check to confirm that the output sound pressure level is greater than the value shown below depending on the type of speaker.
