Isolator Module

Name: Isolator Module
Brand: Dahua
SKU: HY-1431

Stock Code: HY-1431

Isolates a short circuit on the line and keeps the rest of the loop running.

An isolator module for addressable fire detection loops. It separates the section where it detects a short circuit and confines the fault to a single zone.

Key features

WiringIt uses a two-wire, polarity-free line, so installation needs no polarity check.

Short circuit protectionIt acts at a short circuit current of 450 mA and separates the faulty section from the loop.

IndicatorThe red LED flashes once every 6 seconds during polling, drops to 2 seconds on a fault and stays lit during a short circuit.

Operating conditionsIt works between -10°C and +55°C and up to 95% relative humidity.

CertificationIt meets the GB16806-2006 standard.
