RS485 Fence Alarm Systems 4 Lines 2 Zones Tension Sensor Controller Rod Taut

Features

Alarm function:

1) Cable tension alarmWhen the cable is tightened by an external force and the tension change amount and duspecified requirements, an alarm signal should be issued.

2) Rope relaxation alarm: When the cable is relaxed under external force, when the tension change reaches or excrequirement, an alarm signal should be issued.

3) Cable cut alarm: When the cable is cut, an alarm signal should be issued.

4) Tamper alarm: When the tension main housing is disassembled, an alarm signal should be issued.

5) Power off alarm: When the power supply is powered off, it should be switched automatically, powered by tand an alarm signal should be issued.

6) Self-test and fault alarm function

How it works

A screen of metal wires is deployed around the installation's perimeter, connected to exclusive sensor posts equipped with Strain Gauge Sensors. The resistance of the strain gauge changes relative to the distortion of the sensor caused by load changes and the signal processing unit analyzes the signal including its velocity and using imbedded algorithms decides if the signal is an alarm. The Taut Wire System uses advanced technology which allows it to face all weather conditions, for the sake of intrusion detection only
