System Requirements
The Sky Sensor communicates to the View System and receives power via PoE. In CP 3.0 or lower this occurs via external PoE device. CP 5.0 or higher provides PoE direct from the switches.

1. PoE voltage requirements: Class 0, 36 – 57 VDC. Powering device should be Type 1 and not higher.
2. Category CAT5 unshielded cable or above.
3. For CAT5 cable, the maximum cable length is 328 feet (100 meters).

Mounting Requirements

1. Sky Sensor shall be mast mounted on the roof.
2. Elevate sensor height as required to obtain clear line of sight to the horizon for optimum system performance.
3. Top of Sky Sensor shall be mounted at minimum 2-feet above the highest obstruction on the roof of the building. Provide 360 degree unobstructed view horizontal.
4. Ensure mounting height will not be obscured based on average snowfall.
5. Mounting system must be bonded to building ground at the location of electrical junction box.
6. Verify mounting location in field with building owner and View Interconnect Drawings.
7. Mounting system and mast needs to comply with local building codes and withstand high winds based on geographical location.
8. If possible, for a building with a lightning arrestor system, the Sky Sensor and electrical junction box to be installed a minimum of 5-10 meters from any of the lightning rods.
9. For a building with a singular lightning tower, the Sky Sensor should be installed 2 ft. lower the highest point of the lightning tower.
10. When installed, the electrical junction box (EJB) bottom surface needs to be at least 1 ft above ground level.

Installation

Install the Mast

1. Using 3/4” Rigid Metallic Tubing (RMT), mount the mast to the top of the roof using standard industry procedures. Minimum length of the RMT must be 1 ft above the roufing. Ensure the installation complies with local building ordinances. Do not use EMC/EMT.Do not use EMC/EMT.
2. Deburr the top of the mast so that a cable can be routed through the mast and not cause damage to the cable.
3. Install electrical junction box (EJB) to the top of the mast (see Best Known Methods).
4. Add included pipe to top of the EJB for the sky sensor base assembly, make a mark 1-1/4” from the top of this pipe as shown. Make sure the top of the sky sensor is 2-feet above the highest obstruction on the roof.
5. EJB must be bonded to the building ground. Use the provided lug nut on the bottom of the EJB.
6. In case local regulations or windloads dictate, the EJB has mounting ears to attach to a structure. Use 3/4” hardware to secure when necesary.

Install Sky Sensor Base and Route Ethernet Cable

1. Using a Phillips head screwdriver, loosen the three set screws at the base of the Sky Sensor. This will allow you to slide the base down onto the mast.
2. Feed the View supplied 4-foot CAT5 Ethernet cable into the Electrical Junction Box (EJB) until the end of the cable with the dust cap is sitting inside the Sky Sensor Base on top of the mast. Use caution to ensure you don’t damage the RJ45 connector. Leave the metal dust cap on the end of the Ethernet cable during this step.
3. Slide the Sky Sensor base down onto the ½” galvanized steel pipe and ensure the bottom of the Sky Sensor Base lines up with the mark that you made 1-1/4” from the top. If the two align, this indicates that the ½” pipe is fully inserted into the Sky Sensor.
4. Hand tighten the three set screws until firmly secured to the ½” pipe. Note: Do not over tighten and strip the screws. Do not use power tools.
5. Using standard CAT5 Ethernet tester, test end-to-end to confirm Ethernet is not damaged after installation through the mast. Additional testing is required upon final installation.
6. Connect the Sky Sensor cable to the RJ45 Jack labeled as OUT on the EJB surge protector. The top connector on the surge protector is next to the grounding stud, use image for reference.
   NOTE: Connecting the Sky Sensor to the incorrect port will result in damage to the Sensor.

CSS: Connecting to Grounding Coupler and View Control Panel (1.0-3.0)

1. Install Standard Junction Box a maximum of 10 ft. from Control Panel

2. Mount the surge protector to the inside of the Standard Junction box with the four suitable self-tapping screws.

3. Crimp the provided ring lug on a suitable length (site specific) 12AWG THHN green or green/yellow wire (not provided by View) to bond the protector to a designated earth ground. If there is any doubt on the proper facility ground point, consult with the electrician on site.

4. Route the ethernet cable from the EJB to the Standard Junction Box. Connect the cable to the RJ45 Jack labeled as ININ of each surge protector.
   Note: Test the cable like in step 2.5.

5. Connect the extension Ethernet CAT6 unshielded cable (UTP) from the RJ45 Jack labeled as OUT to port J18 on top of the Control Panel. Verify that the other side of the J18 feed-thru couple is connected to the Data+PoE port of the Tripp-Lite PoE injector inside the control panel.

6. Connect the extension Ethernet CAT6 unshielded cable (UTP) from RJ45 Jack labeled as OUT to Port 7 of the NCS switch in the Telco Rack.

Prepare the Sky Sensor Body for installation

1. Using a Phillips screwdriver, loosen the three set screws on the Sky Sensor Body.
2. Remove the dust cap on the bottom inside of the Sky Sensor Body.

Connect Data Cable to Sky Sensor

1. Remove the dust cap from the CAT5 ethernet cable inside the Sky Sensor Base on the mast.
2. Align the RJ 45 connector and the keying feature (see below) and small
   hole on the bottom of the Sky Sensor. Once aligned, carefully press the two together and hand-tighten the black colored sleeve securely to the base of the Sky Sensor.

Mount the Sky Sensor

1. With the RJ45 connected to the Sky Sensor, place it onto the Sky Sensor Base.
2. Using a Phillips screwdriver, tighten the three set screws on the Sky Sensor to secure

it to the Sky Sensor base. The screw will thread into the base until the

head of the screw bottoms-out on the wall of the sensor; it does not need to be tightened past this point.

Sky Sensor Verification

1. Contact View Costumer Support to verify connectivity.

Final Operation Preparation

1. Using an optical cleaning wipe, clean the sensors on the sides and top of the Sky Sensor. Ensure all sensors are free of dust, debris, and oils from fingers.
2. Ensure the Gore Patch on the side of the sensor is not damaged, taped over or covered by silicone.
