Dual Input ModuleOM522

Product Overview

Applied with advanced MCU single-chip micro-processor, Surface Mount Technology and Two-wire non-polarity Input, the OM522 Dual Input Module possesses 2 kinds of encoding methods both auto-encoding of the Control Panel and electro-encoding of the Address Encoder. It also has the function of auto-measuring Voltage between both ends of the module. This module is used together with the Intelligent Fire Alarm Control Panel OZH4800. The auto-encoding method can take reference to the Instruction of the Control Panel. And the electro-encoding method can take reference to the Instruction of the electronic encoder.
The OM522 Dual Input Module is used for monitoring any of NO contact signals of the field devices, like the water-flow indicators, signal valves, pressure switches, etc., when it acted. Then transmits the signal it received to the Fire Alarm Control Panel through the Bus line and showing the location of the signal, lighting the alarm indicator on the faceplate of the module meanwhile (Blinking red continuously is for Fire Alarm and blinking green at normal checking time). The OM522 Dual Input Module occupies 2 addresses and has 2 Input contact signals.
