© 2016 Radio Solutions, Inc. Norwell, MA - USA 8 Description: The RSI SB400M1A is a high gain, high power class B band-selective signal booster (BDA, Bi-Directional Amplifier) that operates in 450-490MHz UHF range. It is intended for enhancing two-way radio signal coverage in buildings, tunnels and other confined areas. The SB400M1A is specifically designed for public safety and other mission-critical applications. The NFPA-compliant version of the signal booster includes a built-in dual power supply system (Fig. 1.1 and 1.2) with a backup battery charging and monitoring system Fig. 1.15). It also includes two sets of alarm connections for status monitoring of the BDA operation(Fig 1.14 and 1.15), antenna systems, battery capacity, power supply monitoring, AC supply, temperatures, RF module status etc. (Fig. 1.14 and 1.15). All alarm conditions are also logged as a simple text file on a removable SD Memory Card. The two separate circuit breakers (Fig 1.3 and 1.4) are provided for easy power hookup and for the increased reliability. The RF modules (Fig 1.6 – 1.11) are mounted on a DIN rail for easy access and serviceability. The unit is factory-set for specific frequencies and bandwidths and other than the gain and power settings, it does not require any other field tuning or programming. Figure 1

The signal booster enclosure has two mounting tabs on top and two on the bottom. For optimal airflow, it is best to maintain at least 1” of spacing between the back of the enclosure and the wall. This is best accomplished by mounting the enclosure on a grounded strut channel (i.e. Unistrut, Kindorf etc.). Please make sure that there is sufficient clearance around the signal booster enclosure to ensure unobstructed airflow. 2. Connect the AC Power - The enclosure has 4 ½” trade size cutouts: two for power, one for battery backup and one for alarm circuits. Diameter of the cutouts is 7/8” to allow for easy installation of ½” trade size conduit fittings. The two power supplies have two separate circuit breakers so that either a one shared circuit or two separate circuits can be connected for backup and redundancy in mission-critical applications. Each one of the two dual circuit breakers has the Line, Neutral and Ground connections. Please make sure that the green ground terminal is connected to the ground wire and that is it secured to the DIN-rail. The DIN rail is the ground path for the enclosure. Warning – Live wire terminals on the circuit breakers! Danger - Electrical Shock Hazard – Any high voltage and electrical ground connections must be done by a qualified electrician. To prevent electrical shock when installing or modifying the system power wiring, disconnect the wiring at the power source before working with uninsulated wires or terminals. Prior to powering up the unit, please make sure that electrical ground is connected to both the DIN-Rail terminals inside the enclosure and to the enclosure grounding bolt located on the underside of the enclosure. AC Power and RF Connections should be installed with all standard installation practices for lightning protection. This includes grounding and electrical bonding together of all equipment enclosures and grounding of the primary antenna cable and the installation of proper surge suppression (lightning arrestor) equipment at the entrance to the building or the equipment room. 3. Connect the Battery Backup – RSI Battery enclosure is designed to be installed directly below the signal booster. Use the provided wire harness to connect batteries to the battery power terminal on the PMU circuit board. Leave the battery fuse out for now. Please only use the RSI supplied or RSI approved batteries. 4. Connect the Antenna system – Underside of the signal booster enclosure has two N-Type connectors - the DAS system connector on the right side and the connector for donor antenna on the left side, as labeled. 50 Ohm coaxial cable jumpers for both DAS (distributed antenna system) and for the donor antenna must have solid outside conductor (such as ¼” - ½” Superflex, Heliax, etc.). Coaxial cables with braided outside conductor may have excessive “signal leakage” that can cause feedback and oscillation of the signal booster, especially when high gain settings are used. Please ensure that both DAS and donor antenna systems are tested before they are connected to the signal booster. Bad antenna connections, antenna line breakages etc. can cause poor performance and RF intermod interference. 5. Power up the signal booster, insert the battery backup fuse

Gain can be increased as needed by setting DIP switches on LNA and ALC modules. Figure 3 shows the LNA module with an example DIP Switch setting of -8dB. This introduces 8dB attenuation to the LNA module. For example, if the rated maximum BDA gain is 90dB then: 90dB – 8dB = 82dB. So the BDA total gain now is 82dB. Figure 4 shows the ALC module with 8dB gain attenuation. With both modules settings as shown, BDA gain is calculated as follows: 90dB – 8dB (LNA Attenuation) – 8dB (ALC Attenuation) = 74dB total gain. System gain needs to be set for both downlink and uplink 7. Set the power limit – signal booster ships from the factory with output power set to minimum. Power limit can be increased as needed by setting DIP switches on the ALC module. Figure 4 shows ALC module with 7dB of power limit deduction. For example, if the maximum BDA power is 32dBm then: 32dBm - 7dB = 25dBm maximum output power. Figure 3 - LNA Module Figure 4 – ALC Module

Connect the Alarms and the Booster Monitoring Annunciator panel (NFPA-Compliant versions olnly) The LED Light Indications: Red “Signal” LED’s on both modules indicate that the ALC (Automatic Level Control) circuit has been activated – i.e. input signal is high enough where amplifier needs to reduce the gain to limit the output power to 32dBm max. The Green “Status” LED’s indicates status of the module. Green LED light indicates that the unit is powered up and no faults have been detected. No LED lights or a red status LED light would indicate a problem with the module, such as: over/under voltage, over/under temperature, over/under current draw or other module fault. All alarm conditions are signaled to the central monitoring unit which then displays the alarm condition on the LCD, logs the alarm condition with the current time stamp to the SD card and activates the BDA fault alarm outputs.

© 2016 Radio Solutions, Inc. Norwell, MA - USA 13 1. Design the Distributed Antenna System (D.A.S) – Design the D.A.S for optimal signal coverage of the building or other confined area. The D.A.S. system can be designed by using a combination of radiating cable, non-radiating cable, antennas, signal taps, splitters or hybrid couplers. To prevent feedback oscillations, a solid outer conductor, non-radiating cable must be used to connect the booster to the D.A.S. and donor antenna systems. If high gain antennas are used, it is important to limit the output power of the signal booster so that the maximum ERP does not exceed the 5W limit (see the warning and calculation instructions on page 2). 2. Locate the Donor Antenna – The Donor antenna should be a high-gain, directional type antenna and should be aimed at the nearest radio system repeater site. Location of the antenna should be chosen so that it provides highest possible signal isolation from the D.A.S. system. It is important to limit the output power of the signal booster so that the maximum ERP does not exceed the 5W limit (see the warning and calculation instructions on page 2). 3. Measure the D.A.S. to Donor Antenna Signal Isolation – Probably the most important step in design and deployment of an in-building signal booster system is to ensure that there is a sufficient signal isolation between the donor antenna and the D.A.S. system. Just like the feedback that occurs when the microphone and speaker get too close together on a public address system, a signal booster can start to oscillate when the gain of the system is higher than the isolation of the antenna system. The oscillations can cause continuous in-band interference to other users that are in the range of the signal booster. To prevent the feedback oscillation from happening it is important to ensure that the amount of antenna isolation is at least 15dB higher than the signal booster gain. Antenna isolation is measured by generating a test signal into the D.A.S. system and measuring the level of the signal received off the donor antenna using a spectrum analyzer or other device capable of accurately measuring RF signal levels. If a directional hybrid couplers are used in the D.A.S. system then the same test should be performed in other direction by generating the test signal into donor antenna and measuring the received signal level from the D.A.S. system. Once the signal separation is measured, deduct 15dB from the figure and the result is the maximum amount of gain that is allowed. Example: Test Signal Level generated into the D.A.S. system: 0dBm Measured Test Signal Level at the Donor Antenna: -70dBm Signal Isolation = 0dBm – 70dBm = 70dB Maximum Booster Gain Allowed: 70dB -15 = 55dB

Follow the Good Engineering Practices and be a Good RF Neighbor - Good engineering practice must be used in regard to the signal booster’s noise radiation. Accordingly, the gain of the signal booster should be set so that the ERP of the output noise from the signal booster should not exceed the level of -43 dBm in 10 kHz measurement bandwidth. In the event that the noise level measured exceeds that value, the signal booster gain should be decreased accordingly. Also, please note that in general, the ERP of noise on a spectrum more than 1 MHz outside of the pass band should not exceed -70 dBm in a 10 kHz measurement bandwidth. 5. Set the Booster Gain using the procedure described on page 10 to the value as determined by following the step 3 and 4. System gain can be further reduced if required by specific site conditions or factors. 6. Set the Booster Power Limit to the desired value using the procedure described on page 10. 7. Power up the Booster and Test the Coverage. Class B broadband signal boosters are permitted to be used only in confined or indoor areas such as buildings, tunnels, underground areas, etc., or in remote areas, i.e., areas where there is little or no risk of interference to other users.
