The colorful flashing balls can indicate different situations of cell phone jammer

Are installed under the floor. 1) strong electric trunk tray selection 400 * 200mm galvanized tray. Bottom height of 0.3 m from the ground. 2) strong electrical tributary bridge use 100 * 100mm galvanized tray in the cabinet. Bottom height of 0.3 m from the ground. 3) building a network bridge selected 300 * 100mm galvanized bridge from the ceiling into the room hosts a dedicated channel. 4) backbone network bridge host room selection 500 * 100mm galvanized tray. Bottom height of 0.4 m from the ground. 5) branch network bridge host room selection 300 * 100mm galvanized tray. Bottom height of 0.4 m from the ground. 6) bridge outside the frame selected 200 * 100mm galvanized bridge outside the wiring from the ceiling into the room. 7) the strength of electrical bridge installation to avoid mutual interference.
The colorful flashing balls can indicate different situations of   cell phone jammer    .Distribution cable 1) room all made high-quality power distribution cables are used ZR-YJV flame retardant power cable. See materials list. Branch pipe from the bridge leads to wear protection. 2) room in the power distribution trunk cables are laid inside the tray. Grounding System 1) separate shield ground. 2) other types of grounding a common grounding. Room floor installation 40 * 4MM ground copper busbar, copper busbar and ground power distribution cabinet composed of rows of rooms equipotential ground bus. The engine room of a variety of ground, such as security, the anti-static grounding and equipment enclosures, cabinets cabinet, metal components are all connected to the grounding wire equipotential ground bus. 3) room floor bracket 16MM composed of braided copper grounding grid spacing 1800 * 1800MM. 4) Each equipment cabinet leads to two 16MM woven copper, received equipotential ground bus. 5) The engine room of the ground wire or ground terminal provided by the building construction, requiring the building grounding resistance of grounding device is less than 1 ohm. It means       cell phone jammer is in the status and it works normally.Room distribution system construction phases 1) a power distribution system includes 2 UPS, 7 power distribution cabinets, counters and the first four columns corresponding distribution cables, power distribution equipment rack 60 slip, non-shielded room distribution.
Structural process: components arranged in a reasonable, neat; wire colors and reasonable cross-section, laying flat; connector firmly; inlet and outlet in line with project needs; c) signs, markers: should be flat clear. d) shall comply with IEC standards for electrical performance air distribution 1) shielded precision air-conditioned indoor air from the shielded room power distribution cabinet. 2) non-shielded non-shielded room VRV air conditioning room air distribution equipment power supply. 3) Air-conditioning and lighting distribution panel master switch shall be linked with the fire, when the fire alarm action, the power cut off air conditioning, lighting, power supplies (start the emergency lighting), so in a timely manner to eliminate the disaster. The intelligent management system of school   cell phone jammer will be centrally controlled.Room lighting 1) According to the room design specification, the average room illumination should be greater than or equal to 500Lx. 2) room lighting use 1200 * 600MM for 3 * 40W fluorescent lamps, the light switch shunt control. 3) The room shall be within a certain interval install emergency lighting. Emergency lighting illumination ≥ 50LX. 4) All rooms are required to install security lights at the exit. Repair the wall socket 1) installed on the room wall socket 250V/10A service five-hole (from the floor 0.3 meters), distance of 5-8 meters apart. 2) by the corresponding power distribution cabinet lighting, air-conditioning supply. Bridge bridge into a strong distribution power distribution backbone network backbone bridge and bridge.The intelligent management system of school   cell phone jammer     will be managed through the man-machine operation interface of the main control software.
