Product OverviewApplied with advanced MCU single-chip micro-processor, Surface Mount Technology and Two-wire non-polarity Input, the OM521 Dual Output 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 OM521 Dual Output Module receives the programmed commands from the Control Panel and controls 2 groups of the Output signals: NO or NC signal, in order to start the field linkage equipments. Then it receives 2 Feedback signals sent by the linkage equipments after action and transmits the signals of Started and Feedback back to the Control Panel showing the location of the signals, meanwhile lighting the LED indicator (Blinking green at normal state and Blinking red continuously when Start and Feedback). The OM521 Dual Output Module occupies 2 addresses and has 2 Output groups.SpecificationsSupply Voltage: Two-wire bus, DC20V~DC28V, non-polarity; External power, DC24VConsuming Current of Relay Starting: < 30mAStandby Current of Bus: < 0.3mA Alarm Current of Bus: < 0.6mACapacity of the Relay Contact: DC24V, 1A Range of the address: 1~192Size: 96×65×37mm (length × width × height)Using Environment: Temperature: –10°C~+50°C Related Humidity: ≤95% (40±2°C)
