### Industrial Telecom Power Distribution FSU Vibration Monitor System Kit
SIMPLE LAYMAN GUIDE - HOW THIS SYSTEM WORKSThis complete security kit protects remote equipment boxes, solar panel frames, gate structures, or container rooms against physical break-ins, hammering, cutting, and drilling. You do not need complex engineering knowledge to understand the setup:The Isolated Power Box (DOM-48D35S12): Takes raw high-voltage battery or solar tower power and drops it down safely to a steady 12V stream of household-safe electricity.The Control Brain Card (ED972ZTE): Acts as the central smart hub. It uses that safe power to stay awake 24/7 and monitor your security loop lines.The Vibration Sensors (4 x ED702): These compact sensor blocks mount directly to your security walls, fences, or container doors. If someone tries to cut a wire, drill, or hammer the wall, the sensor chain instantly snaps.The Outdoor Warning Siren (KF81TX): The exact second the control brain detects a sensor wire break, it triggers this rugged strobe box, launching a loud alarm sound and a bright flashing light to stop intruders.
De-risk your next private cellular deployment, base station maintenance project, or remote telemetry shelter refresh. Up for sale is a specialized, carrier-grade Field Supervision Unit (FSU) power distribution and vibration monitor system ecosystem bundle. Specially engineered by telecom infrastructure partners, this hardware matrix is designed to monitor and safeguard remote telecommunication enclosures, cellular base stations, and fiber-optic distribution hubs against critical structural impacts, tampering, and line noise.
The system utilizes an advanced, galvanic-isolated step-down power converter running a continuous, tamper-protected Normally Closed (NC) loop array across multiple high-precision shock and environmental sensor nodes.
#### System Logic & Operational Flow
* Power Conversion: The DOM-48D35S12 module swallows raw site power (-48V DC nominal) and cleanly drops it to a stable 12V DC bus line.
* System Power: This clean 12V line continuously runs the ED972ZTE Control Card and feeds standby potential to the KF81TX Siren.
* Loop Monitoring: The four ED702 Sensors are wired together in a continuous, tamper-protected Normally Closed (NC) loop monitored by the ZTE controller.
* Alarm Activation: If any sensor detects a physical strike, persistent drilling, or environmental breach, the loop breaks. The ED972ZTE card detects this fault and switches 12V DC power straight to the KF81TX Strobe Siren, activating visual and audible deterrents.
