Honeywell X-NRI/EN Network Resource Interface

Description

Honeywell’s X-NRI/EN Network Resource Interface applies the main power supply and a 24 VDC backup power supply. By default, the device is running on the main power. When the main power is disabled, it automatically relays to a backup power supply. As the main power resumes normal, the power supply switches back to the main power.

The X-NRI/EN has main power protection. When an internal short circuit or other forms of malfunction happens, the main power supply will be cut off to protect the device. By self-detection, it can detect faults in the main/backup power supply, system malfunction, and communication faults. Whenever there is a fault, the indicator turns yellow and the siren goes off to warn the operators, while the fault status is logged.

X-NRI/EN has 4 RCA terminals for external audio source input. External audio sources can be connected to XNRI/EN directly such as CDs or DVDs. Through XSMART software, the voice alarm zones of each XDCS2000/EN can be pre-configured and overridden by the BGM broadcast using the recorded emergency voice message. It can also deliver different evacuation messages which were pre-set in each adjacent zone.

Features: 

• 4 AUX balanced audio input for digitalization of the external analog audio source and routing to the network
• With built-in 512MB Flash memory and 4G SD card as an internal audio source 
• 4 Ethernet interfaces allow communication of multiple X-DCS2000/EN
• 32 x dry contact control inputs with supervision and input faults can be monitored
• 2 x RS-485 communication terminals for integration with Fire Panel via protocol
