This compensates for weak reception caused by distance, topography, building structure, etc. The BDA receives the signal from an outside antenna, amplifies that signal, and then rebroadcasts it via antenna(s) inside the building, where it can then be picked up by radios inside. In the reverse direction, interior antennas also pick up signals coming from radios, where they are amplified by the BDA, and then passed to the exterior antenna for rebroadcast back to the tower. 1.7 A Word About Safety Follow all safety precautions in this manual.

1. Choose a mounting location for the exterior antenna. The recommended Yagi directional antenna is, pointed directly at the radio tower (line of sight). The antenna is typically mounted on the wall or roof of the side of the building with the strongest signal. A grounded lightning protector is required between the exterior antenna and the BDA. 2. Next, choose the mounting location of the interior antenna(s), being sure to take separation requirements into account. Long, narrow spaces benefit most from directional flat-panel antennas, while more square spaces benefit more from omnidirectional dome antennas. 3. Choose where to mount the BDA. This should be in a secure indoor location near a grounded power source. 4. Map the cabling route between the exterior antenna and the BDA and between the BDA and interior antennas. 5. Proceed with a soft installation connecting components without securing their placement until testing can be completed. 6. Power on the BDA and perform configuration and testing explained in Chapter 5. 7. Complete installation by securing the placement of the BDA, antennas and other components, Important Installation Safety Precautions:

The exterior antenna must not be co-located or operating in conjunction with any other antenna. Always use a properly installed SureCall lightning protector between the exterior antenna and the BDA. Always power off the BDA before working on the roof of the building, or anywhere in close proximity to the external antenna. Comply with all antenna separation requirements to prevent signal oscillation. CAUTION: FAILURE TO PROPERLY INSTALL A LIGHTNING PRO- TECTOR CAN RESULT IN DAMAGE TO THE BDA, ANTENNAS, AND WIRING. CAUTION: SIGNAL OSCILLATION CAN CAUSE RADIO INTERFER- ENCE WITH RADIO TOWERS AND RESULT IN CIVIL AND/OR CRIMINAL PENALTIES. 3.2 Exterior Antenna Overview The Yagi antenna receives and transmits signals over a focused area. It must be aimed directly (line of sight) toward the radio tower that provides the strongest signal to the building. The exterior antenna and mast (if any) must be mounted in a location that meets all of the following criteria:

16 Best signal strength. Not co-located with other antennas or used in conjunction with other antennas. Away from all power lines. At least 6 ft. from lightning rod antennas. At least 8 in. from any person. These distances are general guidelines only. Refer to the applicable building and electrical codes in your area to determine specific local requirements. 3.3 Interior Antenna Overview You may use any combination of omnidirectional (dome) and/or directional (flat panel) interior antennas to obtain balanced signal strength throughout the structure. Dome antennas provide 360-degree hemispherical coverage suitable for mostly square areas, while flat panel antennas provide a focused zone of coverage suitable for long narrow areas. The example above uses two dome antennas and one panel antenna to provide full coverage Keep in mind that floor structures in multistory buildings can cause significant signal loss, which means that you may need to install interior antennas on more than one floor. Here is an example of a multistory installation:

Note: You may not need antennas on every floor of a multistory building, depending on factors such as building material, BDA gain, etc. 3.4 Antenna Separation Proper antenna separation prevents signal oscillation (feedback) that can interfere with the radio tower. Separation is measured in a straight line from the exterior antenna to the closest interior antenna. The closest allowable distance depends on a number of factors, such as BDA gain level, building material, etc. Recommended separation distances are:

Vertical separation is more important than horizontal separation. If you are unable to obtain the required separation horizontally, try raising the exterior antenna. You may also try reducing the BDA gain as described in Chapter 5 of this manual. Antenna Safety Precautions:

You can mix and match dome and directional antennas as needed to obtain proper coverage throughout the building or area where you need to boost the signal. If you use a Yagi exterior antenna, you should normally aim it away from all interior antennas, regardless of separation, to prevent oscillation.

Away from tightly enclosed or overly hot spaces Near a properly grounded 110VAC outlet Power and warning lights are easily visible Shortest possible cable runs to all antennas 3.6 Accessories The final step in the planning process is to make sure you have all of the necessary accessories to complete the installation. You will need all of the items listed in Chapter 1 of this manual plus some or all of the following:

Cable clips: Use these to secure the cables to interior and exterior walls/ceilings. Appropriately rated sealant/caulking to waterproof exterior cable entry points Hand and/or power tools as needed to complete the installation Personal Equipment (PPE): Use all PPE required by local codes and/or best practices to help ensure personal safety during installation. CAUTION: YOU ARE RESPONSIBLE FOR ENSURING THAT THE INSTALLATION MEETS ALL APPLICABLE CODES. Note: You may need to obtain a permit from your local building department to install the BDA and antennas. Check your local building and/or electrical codes. 3.7 Alert These draw the attention of personnel to hazards that may cause damage to the equipment. An example of use is the case of static electricity hazard. Caution notices may also be used in the handbook to draw attention to matters that do not constitute a risk of causing damage to the equipment but where there is a possibility of seriously impairing its performance, e.g. by mishandling or gross maladjustment. Warnings and Cautions within the main text do not incorporate labels and may be in shortened form. Caution risk of explosion if battery is replaced by an incorrect type dispose of used batteries according to the instructions. Disconnection of the 2 RF connectors may cause damage to the equipment when power is on. The application antenna and RF cable are not provided. The antenna gain should not exceed 3 dBi for downlink and 6 dBi for uplink, and the shortest distance from human is 0.8843m.. Caution messages for use of unauthorized antennas, cables, and/or coupling devices not conforming with ERP/EIRP and/or indoor-only restrictions. 3.8 Need Help?

Call: 1-888-365-6283, 7 a.m. to 5 p.m. PST, Monday Friday Email: support@surecall.com CHAPTER 4: INSTALLATION 4.1 Soft Installation Perform a soft installation of all components to test signal coverage and oscillation before making the installation permanent. Avoid making holes or other permanent attachments during this phase. Refer to Chapter 5 for configuration and testing instructions. Proceed with final installation once configuration and testing are complete. 4.2 Exterior Antenna Mount the exterior antenna in the location you selected during planning. Follow all of the instructions included with the antenna to ensure that your installation is done properly. Here are a few reminders and essential steps:

A Yagi antenna is mounted horizontally with drip hole facing down and aimed at the desired radio tower (line of sight). Mount the antenna. Connect a length of cable to the antenna and hand-tighten. Run the cable along the planned route. Install a properly grounded SC-LP lightning protector. Seal any exterior cable entry points on building exterior with caulking or sealant. WARNING: DO NOT TOUCH ANY LIVE ELECTRICAL WIRES OR ALLOW THE ANTENNA OR CABLING TO TOUCH ANY LIVE ELECTRICAL WIRES. CAUTION: AVOID AIMING A YAGI ANTENNA TOWARD ANY INTERIOR ANTENNA. 20 4.3 Interior Antennas Mount the interior antenna(s) in the location(s) you selected when planning. Follow all instructions included with the antenna(s) to ensure the installation(s) are done properly. Here are a few reminders and essential steps:

Dome antennas are mounted on the ceiling as close to the center of the desired coverage area as possible, domed (convex) side pointing down. Flat panel antennas should be wall-mounted as close as possible to the center of the wall, or at one end of long narrow space. Mount the antenna. Connect a length of cable to the antenna and tighten until hand-tight. If you are installing multiple antennas, run the cable to the splitter location and connect the cable to one of the outputs on the splitter. Connect another length of cable to the input side of the splitter (if used) and run this cable to the BDA location. It is important to keep the cable runs equal or use taps to ensure a harmonious install. CAUTION: VERIFY THAT ALL INTERIOR ANTENNAS MEET THE SEPARATION REQUIREMENTS DESCRIBED IN THE PREVIOUS CHAPTER, AND THAT NO ANTENNA IS AIMED TOWARD THE EXTERIOR ANTENNA. CAUTION:DO NOT CONNECTAN INTERIORANTENNATO THE SPLITTER INPUT. 4.4 Mounting the BDA Mount the GuardianA as follows:

Verify that the selected location meets all criteria described in the previous chapter. Mount a 24 inch x 24 inch x 34 inch thick sheet of plywood on top of sheetrock, secured into wall studs where the NEMA housing is to be placed. The plywood should be flush against wall. Once the plywood is secure, attach the NEMA housing to the plywood base using the screws provided. In most installations, the housing will be oriented so the I/O ports are facing down. Connect the outdoor antenna cable to the signal booster connector port marked OUTSIDE and tighten the connection. Connect the outdoor antenna cable to the signal booster connector port marked INSIDE and tighten the connection. CAUTION: DO NOT POWER ON THE BDA UNTIL INSTRUCTED TO DO SO. CAUTION: NEVER POWER ON THE BDA WHEN ANY ANTENNAS ARE DISCONNECTED AS THIS COULD DAMAGE THE BDA. CHAPTER 5: CONFIGURATION & TESTING 5.1 Powering on the BDA 1. Make sure the exterior and interior antenna cables are firmly connected to their corresponding ports on the NEMA-4 enclosure. 2. Plug a surge suppressor into a grounded 110VAC wall outlet. 3. Plug the AC end of the power adapter (supplied with your BDA) into the surge suppressor. 4. Plug the DC end of the power adapter into the Power port on the NEMA enclosure. 5. Verify that the green Power light is illuminated. 6. When the booster is turned on, the band lights will flash red and yellow for approximately 10 seconds. CAUTION: ONLY USE THE POWER SUPPLY INCLUDED WITH THE BDA. USE OF ANOTHER POWER SUPPLY COULD DAMAGE THE BDA AND/OR POWER SUPPLY. CAUTION: DO NOT PROCEED BEYOND THIS POINT UNTIL THE BDA IS POWERED ON AND NO RED WARNING LIGHTS ARE ILLUMINATED. 22 5.2 DIP Switch Configuration By default, all DIP switches are turned in the OFF position, which provides maximum gain to all channels. To access digital channelization, see "Chapter 7: Sentry Configuration & Monitoring" on page 26. Note that attenuation made through Sentry software is cumulative with that of the Boosters DIP switches. BEFORE INITIAL CONFIGURATION, set booster switches with high, but not full, attenuation (as full attenuation would cause the band to shut off). DURING CONFIGURATION, you may add gain incrementally until the signal level has improved enough to meet safety requirements. Note that red flashing lights indicate the system has detected oscillation for the corresponding channel(s). The band will turn off if adjustments are not made. When adjusting booster attenuation, full power is not always the best option. The goal is to obtain a signal level throughout the building that meets safety requirements. NOTE: TURN ALL UPLINK DIP SWITCHES TO ON AND ADJUST THEM BACK ONE STEP AT A TIME UNTIL UPLINK CONNECTIVITY IS MADE WITH THE EMERGENCY RADIO TOWER. The following diagrams and notes explain how to interpret, and use, these switch banks. DIP switch organization PS 700 DL DIP switches control 700 band downlink PS UL DIP switches control 700 band and 800 band uplink PS 800 DL DIP switches control 800 band downlink ATTENUATION THROUGH SENTRY SOFTWARE IS CUMULATIVE WITH THAT OF THE BOOSTERS DIP SWITCHES.

few practical attenuation examples:

Important Note: Turn ALL uplink attenuations dip switches to ON and adjust them back one step at a time until uplink connectivity is made with the Emergency Radio Tower. Turning all switches OFF = 0 dB attenuation (booster is at full gain). Turning ON switch #1 in a bank = 1 dB attenuation (booster maximum gain is reduced by 1 dB). Turning ON switches #1, 3, and 5 in a bank = 1+4+16 dB attenuation = 21 dB attenuation. For example, in an 80 dB booster, the selected channel is reduced to 59 dB (80 dB -21 dB). Turning ON all switches in a bank = 1+2+4+8+16 dB attenuation = 31 dB attenuation. For example, in an 80 dB booster, the selected channel is reduced to 49 dB (80 dB-31 dB). When the BDA is powered on, the green Power Light (3) should illuminate. If any of the bands are oscillating, the corresponding band lights

(1 and/or 2) will flash red and that band will eventually shut down if adjustments are not made. Note: In general, the uplink and downlink DIP switches should be set identically but this is not always the case. 24 CHAPTER 6: TESTING AND TROUBLESHOOTING 6.1 Band LED Conditions This section will help you interpret the LED indicators on your GuardianA. But first, here are a few configuration and testing points to keep in mind:

SILENCING PS700 POWER PS800 If the control light for a specific frequency band is flashing red or red-yellow, try increasing the antenna separation between the inside and outside antennas as much as possible first, then restarting the booster. Attenuation can be lowered to a maximum of 25 dB through sentry software and maximum of 31 dB using the boosters dip switches. Attenuation greater than 25 dB (either made by the boosters dip switches or cumulative adjustments of dip switches and software) will cause the affected band to shut off and display a solid red led. 6.2 LED Conditions LED INDICATIONS LED Color LED Condition Resolution GREEN ON Normal operation. RED FLASHING Indicates Oscillation RED SOLID RF link is off Call: 1-888-365-6283 Email: support@surecall.com 6.3 Testing & Troubleshooting GREEN FLASHING Normal operation. The Automatic Gain Control (AGC) is self-adjusting. Refer to your Sentry Monitoring Software for more information about LED codes. Meanwhile, if you have any questions during setup, please reach out to our U.S.-based support technicians:

Once the booster is powered on (and no Warning lights are on), assess the signal in locations of needed signal improvement. Refine the antenna locations and/or gain levels as needed, then complete the permanent installation when you are confident the system will perform well. A few tips and some perspective:

As a general rule, increasing gain by 6dB doubles the coverage distance of the interior antennas. Start at the lowest gain and increase Its not realistic to expect full reception everywhere in the building. gradually as needed. If one or more red Warning lights comes on, it indicates there is oscillation in that band and adjustments are needed If you cant get the coverage reasonably well-balanced, you may need to install an additional interior antenna and/or a different type of interior antenna and/or relocate interior antennas.
