Introduction Introducing SureCall’s CM2020, Industrial booster Please read this entire manual before proceeding. with the installation. This manual applies to the CM2020 Industrial model. 1.1 - Package Contents Your booster box contains the following items: • CM2020 Booster. • Mounting kit (not shown). • DC power supply (not shown). • Wall anchors (not shown). 1.
Safety • Sufficient SC-400 ultra low loss interior/exterior cable (for boosters above 55dB). • Sufficient SC-240 ultra low loss interior/exterior cable (for boosters 55dB and below). • Up to 6 internal antennas (such as the SC-222W, SC-223, or SC-224 omnidirectional domes and/orSC-248W flat panel by SureCall). • Grounded surge suppressor for DC power 1.
Safety Some components may be heavy and/or bulky. Always use proper lifting and carrying techniques when handling components, especially when working on a ladder, roof, or other area with a fall hazard. • 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 booster.
Planning CHAPTER 3: Planning 3.1 - Overview The general booster installation process follows these steps: 1. Decide where to mount the exterior antenna. This will generally be on the wall or roof of the building in the location with the strongest signal. You will need to decide whether to use an omnidirectional antenna mounted vertically or a directional Yagi antenna pointed directly at the cellular tower (line of sight).
Planning 3.2 - Exterior Antenna You may use either an omnidirectional antenna such as the SC-100-L (flat area with no obstructions) or a directional Yagi antenna such as the SC-230W (to point directly at the tower). The omnidirectional antenna receives and transmits signals over a horizontal 360-degree circle while the Yagi antenna receives and transmits signals over a focused area and must be aimed directly (line of sight) toward the cellular tower that provides the best signal to the building.
planning 3.3 - Interior Antennas You may use any combination of omnidirectional (dome) and/or directional (flat panel) interior antennas needed to obtain optimal signal strength throughout the building or installation area. Dome antennas such as the SC-222W, SC-223 and SC-224 provide 360-degree hemispherical coverage suitable for mostly square areas while flat panel antennas such as the SC-248W provide a focused zone of coverage suitable for long narrow areas.
planning Note: You may or may not need antennas on every floor of a multistory building depending on factors such as building material, booster gain, etc. 3.4 - Antenna Separation Proper antenna separation is essential in order to prevent signal oscillation (feedback) that can interfere with the cellular tower. Separation is measured in a straight line from the exterior antenna to the closest interior antenna.
planning The easiest way to calculate the straight-line separation between antennas is to break it down into three simple measurements and then use some basic geometry to find the distance, as follows: 1. Measure the distances ab, bc, and cd as shown in the diagram on the next page. - Distance from the nearest interior antenna (Point a) to the wall underneath the exterior antenna (Point b). This is distance ab. - Distance from Point b to directly underneath the exterior antenna. This is Point (c).
Planning Separate interior antennas based on the calculations shown in Section 3.5. You may 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 are using a Yagi exterior antenna, you should normally aim it away from all interior antennas regardless of separation to prevent oscillation.
Planning • Inside antenna gain (IAG): This is the signal boost provided by an interior antenna and is always a positive number with SureCall antennas. SC-222W omni dome SC-223 omni dome SC-248 Directional panel +3 +3 +7 +3 +3 +10 • Cable loss (CL): This is the signal loss caused by the cable and is always a negative number.
Planning 3.6 - Booster Location Select an indoor location for the booster that meets the following criteria: • Wall or ceiling mounts are acceptable. • Near a properly grounded 110VAC outlet. • Not in a tightly enclosed or overly hot space. • All power and warning lights easily visible. • Least amount of cable to connect all antennas. 3.7 - Accessories The final step in the planning process is to make sure you have all of the necessary accessories to complete the installation.
Installation Chapter 4. This chapter describes how to install the booster and antennas for best results. 4.1 - Selecting the Locations Select the locations for the exterior antenna, interior antenna(s), booster, cables, and accessories as described in the previous chapter. CAUTION: FAILURE TO PROPERLY PLAN THE BOOSTER INSTALLATION CAN CAUSE SIGNAL OSCILLATION AND/OR OTHER EQUIPMENT MALFUNCTION. 4.
Installation CAUTION: MOUNT THE EXTERIOR ANTENNA ON A FIXED STRUCTURE. WARNING: FAILURE TO EXERCISE CAUTION WHEN WORKING IN HIGH AREAS COULD CAUSE A FALL AND PERSONAL INJURY. 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. 1. Mount the antenna. 2. Connect a length of SC-400 cable to the 3. Run the cable along the planned route. 4.
Installation 4.4 - Internal Antennas Mount the interior antenna(s) in the location(s) you selected during the planning process. Be sure to follow the instructions included with the antenna(s) for a safe installation. Remember: • Dome antennas (SC-222W, SC-223, etc.) should be mounted in the ceiling as close to the center of the desired coverage area as possible with the domed side pointing down.
Installation 4.5 - Mounting the Booster Mount the booster as follows: 1. Verify that the selected location meets all of the criteria described in the previous chapter. 2. Attach the included mounting kit to the booster using the screws provided. Tighten the screws by hand with a screwdriver until tight plus 1/4 to 1/2 turn. Do not over-tighten. 3. Mount the booster to the wall using appropriate screws and/or wall anchors.
Configuration & Testing CHAPTER 5: Configuration & Testing This chapter describes how to power on, configure, and test the booster. 5.1 - DIP Switches and Lights The CM2020 Industrial booster has the following indicators and controls: • PCS Uplink Warning light/DIP switches (1): These DIP switches control the PCS communications with the cellular tower. • PCS Downlink Warning light/DIP switches (2): These DIP switches control the PCS amplification within the building.
Configuration & Testing When the booster is powered on: • The green Power light (3) should illuminate. • The red Warning lights (1, 2, 4, 5) should remain OFF. If one or more Warning lights illuminates, power off the booster immediately. Each bank of DIP switches contains five switches. • Moving a switch down (away from the indicator lights) turns that switch OFF and increases booster gain for the selected channel.
Configuration & Testing 2. Plug a surge suppressor into a grounded 110VAC wall outlet. 3. Plug the AC end of the power adapter that came with the booster into the surge suppressor. 4. Plug the DC end of the power adapter into the Power port on the booster. CAUTION: ONLY USE THE POWER SUPPLY INCLUDED WITH THE BOOSTER. USE OF ANOTHER POWER SUPPLY COULD DAMAGE THE BOOSTER AND/OR POWER SUPPLY. 5. Verify that the green Power light is illuminated. 6.
Configuration & Testing 5.4 – Testing Once the booster is powered on and no Warning lights are illuminated, walk around the entire area to test the voice and/or data signal. Refine the antenna locations and/or gain levels as needed, and then complete the permanent installation once the system is working as desired. 5.5 - Adjusting the Booster Keep the following points in mind when adjusting the booster: • Full power is not always your best option.
Warranty 2. If oscillation occurs on the PCS side, lights 1 and/or 2 will blink as appropriate and the Power light (3) will turn red if it is not already red because of cellular oscillation. 3. If the problem is not resolved, the affected side will shut down after 30 seconds. In general the cellular side will oscillate more easily than the PCS side. 4. The booster will wake back up. When this occurs, the power light will be green. If oscillation resumes, the lights will flash as previously described.
