Description

Firstly, Edwards Est M500XF Isolator Module is an automatic switch that opens when the line voltage drops below four volts. Isolator modules should be space between groups of sensors or modules in a loop to protect the rest of the loop.

The Edwards Est M500XF Fault Isolator Module can be used to supervise as well as activate sounders, strobes, door closers, pull stations, waterflow switches, conventional smoke detectors, and more. Also, each Edwards Est M500XF Fault Isolator Module is rigorously design and test for electromagnetic compatibility and environmental reliability, in many cases exceeding industry standards.

All existing FAST / System Sensor addressable devices can be reuse with the 3-AADC1 module. Some old FAST / System Sensor addressable devices have no equivalent and may no longer be available. Please contact us directly for alternative solutions.

In general, Addressable Analog circuit cable must be a minimum of 18 gauge twist pair with 6 twists per foot. This cable may be unshield or shield as required. Shielded cable is recommend where electrical noise might interfere with data transmission. If a shielded wire is use, it must be use through the entire length of the circuit. Besides, distance limits are determine using the maximum allowable circuit resistance and capacitance, and the manufacturer’s cable specifications.
