CHAPTER 1: INTRODUCTION & OVERVIEW 1.1 Product Overview GuardianB 1/2W is a Class B, 1/2‐watt, bi‐directional amplifier with a maximum gain of 80 dB supporting both the 700 and 800 MHz Public Safety frequency bands.
1.5 Optional Accessories TowerIQ provides many optional features and accessories for the GuardianB amplifier. Note, some component options are listed in table below. Not all accessories are listed. See your TowerIQ salesperson for all compatible part numbers Outdoor Antenna Options Directional Wide Band 50Ω Yagi Antenna (698‐960 MHz); N‐Female connectors; 9 dBi. Note: The sum of antenna gain (dBi) and cable loss (dB) cannot exceed 9.
1.6 How it Works The GuardianB amplifies signals that reach a building from the nearest radio tower, and from radios inside the building going back to the tower. 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.

CHAPTER 3: PLANNING THE INSTALLATION 3.1 Installation Overview Typically, a BDA installation follows these steps: 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.
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.
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 dependson a number of factors, such as BDA gain level, building material, etc. Recommended separation distances are: Amplifier gain Min.
3.5 BDA Location Select an indoor location for the BDA that meets the following criteria: • Indoor dry • Ambient air temperature is 25°C • Away from tightly enclosed or overly hot spaces • 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.
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.
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.
4.4 Mounting the BDA Mount the GuardianB as follows: • • • • • Verify that the selected location meets all criteria described in the previous chapter. Mount a 24 inch x 24 inch x 3⁄4 inch thick sheet of plywood on top of sheetrock, secured into wall studs where the Type 4 housing is to be placed. The plywood should be flush against wall. Once the plywood is secure, attach the Type 4 housing to the plywood base using the screws provided.
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 Type 4 enclosure. 2. Verify that the green Power light is illuminated. 3. 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 THEBDA. USE OF ANOTHER POWER SUPPLY COULD DAMAGE THEBDA AND/OR POWER SUPPLY.
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. The following diagrams and notes explain how to interpret, and use, these switch banks.

CHAPTER 6: MAINTENANCE AND TROUBLESHOOTING 6.1 Band LED Conditions This section will help you interpret the LED indicators on your GuardianB. 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.
7.1 Sentry Software Introduction TowerIQ’s Sentry is a revolutionary advancement in signal‐booster management. It aids in the installation, optimization, and ongoing management of your GuardianB BDA. It provides installers with tools for seamless system configurations, and it helps pinpoint malfunctions due to unforeseen changes in the amplifier landscape, such as new towers or repeater systems. Sentry also notifies installers or end users about various parameters via email.
7.3 Hardware Installation Once the Sentry software is installed, you can proceed to connect and configure the GuardianB BDA. To install the hardware, first complete the following steps: To Computer USB To NFPA GuardianB’s USB To Network server Computer USB • • To Ethernet Computer USB USB Connection: Use a USB cable to connect your computer directly to the GuardianB USB port. The USB connection on the GuardianB is accessible by opening the Type 4 enclosure.
7.4 User Registration You’ll need to register an account. Connect your computer to the network.

7.6 Sentry Operation Leaving all DIP switches off by default allows the AGC to adjust gain as needed. The absence of red LEDs indicates that the system is working as intended. ATTENUATION THROUGH SENTRY SOFTWARE IS CUMULATIVE WITH THAT OF THE BOOSTER’S DIP SWITCHES. ATTENUATION GREATER THAN 25 DB (EITHER MADE BY THE BOOSTER’S DIP SWITCHESOR CUMULATIVEADJUSTMENTS OF DIPSWITCHES AND SOFTWARE) WILL CAUSE THE AFFECTED BAND TOSHUT OFF AND DISPLAY A SOLID RED LED.
RF State • PS700 and PS800 share the same uplink RF link. Setting the Uplink attenuation on this page between 1 and 25 will simultaneously set the equivalent value for all uplink channels for both PS700 and PS800. • PS700 downlink Attenuation is used to attenuate the downlink gain for 700MHz band. Inputting any value between 1 and 25 will set the equivalent value for all downlink channels in this band. • PS800 downlink Attenuation is used to attenuate the downlink gain for the 800MHz band.
