Top Benefits

• Scales easily as buildings grow
  When a single amplifier can’t cover everything, this unit gives you a clean way to extend coverage without duplicating the whole system
• Fiber backbone keeps signal strong across long distances
  Unlike copper runs, fiber ensures there's no loss between the master and remote units—even over hundreds of feet
• Reduces weak zones in high-demand spaces
  Ideal for bringing signal into dead spots like interior offices, large meeting areas, or below-ground rooms
• Simplifies setup with smart tools
  Built-in Bluetooth app shows real-time signal strength and separation for faster, more accurate installs

Maintains uptime with remote access SureCall Cloud platform lets IT teams monitor booster status from anywhere, reducing guesswork and maintenance calls

The SC-MaxFiberRU is the official add-on kit for expanding a SureCall SignalMax Fiber DAS system. It includes everything needed to add one remote unit and connect it to the existing master unit.

Included Components:

• (1) SureCall Remote Unit (SC-FRU)
• (1) 250 ft single-mode fiber optic cable, factory-terminated (SC-SMF250)
• (4) 2-watt termination load connectors rated up to 6 GHz (TL2W)
• (1) 24VDC power supply for the remote unit
  
  

This kit is designed to connect directly to the fiber output of the master unit and support up to four inside antennas (antennas and coaxial cable sold separately or included in full system kits).

Coverage Area Expectations

The SignalMax Fiber DAS Remote Unit distributes signal to up to four inside antennas. Each remote unit typically adds 25,000 to 50,000 square feet of indoor coverage, depending on building layout and signal quality delivered from the master unit.

Use the following as a general reference per remote unit:

• Excellent signal from master unit (fed by a strong outside signal):
  Up to 50,000 sq ft of indoor coverage across four antennas
• Moderate signal from master unit:
  Expect around 30,000 to 40,000 sq ft
• Weaker input signal from master unit or challenging building conditions:
  May provide 20,000 to 25,000 sq ft per remote unit

Note: Coverage can be improved by adjusting antenna placement and ensuring proper spacing between donor and server antennas in the system. The stronger the signal entering the master unit, the better the performance you’ll get at each remote unit.

Installing the SureCall SignalMax Fiber DAS Remote Unit (SC-FRU) is a straightforward process for professionals familiar with fiber and coax systems. This unit is designed to work in tandem with an existing SignalMax master unit and should not be installed as a standalone system.

Here’s a high-level breakdown of what the installation involves:

1. Choose a Location

Mount the remote unit indoors, preferably on a wall or flat surface near an AC power outlet. The location should be central to the coverage area you’re targeting and allow for coax runs to up to four indoor antennas. Avoid areas near excessive heat, moisture, or direct sunlight.

2. Run the Fiber Connection

Use the included 250-foot single-mode fiber optic cable to connect the remote unit to the master unit. The fiber should plug into the SC UPC port labeled "Optic" on both ends. Be sure to avoid sharp bends or tight loops when routing the fiber.

3. Install Indoor Antennas

Connect up to four inside antennas to the RF ports on the remote unit using SC-400 coaxial cable (not included in this add-on kit). Each antenna should be ceiling-mounted in areas where you want to improve signal. Keep antennas well spaced from each other and from the building’s exterior walls to avoid interference.

Installer Tips:

4. Connect to Power

Plug the included 24VDC power supply into the remote unit and a standard 110V AC outlet. A power extension cable may be used if needed, but always check that the supply voltage matches the system requirements.

Important: Do not power on the system until all fiber and RF connections are complete.

5. Use the SureCall App for Optimization

Once the unit is powered on, use the SureCall Bluetooth mobile app to check signal performance. The app helps you:

This step is essential for confirming proper setup before securing hardware in place.
