Environmental control system,1U 19'' installation,smoke,water leak,temp/humidity alarm sensors

Model Number: WB-NEM500 Brand Name: WebiTelecomms Key Specifications/Special Features: The WB-NEM-500 is a small high-reliability environment monitoring unit developed to provide environment/device controland remote monitoring for communications base stations, integrated equipment rooms, and out-door cabinets.The monitoring unit monitors important environmental factors such as temperature, humidity, smog, water penetration,access control, vibration/leaning, main distribution frame (MDF), and surge protection device (SPD). When any valuecollected by a sensor exceeds the preset threshold, an alarm is sent through the LCD, buzzer, or system log.The monitoring unit also provides complete device detection functions, such as switch power status detection.Through a preserved custom interface (optional), the unit can be connected to another sensor in main contact pointoutput type.2. Features2.1 Front maintenance (front cabling): higher space utilization and easy maintenance2.2 Combat structure: standard 1U/19-inch chassis for easy installation
2.3 Monitoring of cabinet switch power: The monitoring unit can be connected to the switch power for transparent
data transmission and forwarding. The complete monitoring functionality is to be developed based on standard
communications protocols.
2.4 Uploading over standard protocols: The monitoring unit uploads environment data to the monitoring background
and receives remote system commands over specified protocols in main contact point or RS485/232/IP mode.
2.5 Complete monitoring functionality: The monitoring unit intelligently controls all environment devices in an
equipment room, and automatically monitors environment parameters against the alarm thresholds from remote.
2.6 GUI-based host computer control software:
2.7 Various sensors supported: The monitoring unit can be connected to various analog-output sensors,
switch-output sensors, and RS232, RS485 interface sensors.
2.8 Built-in common sensors for simplified cabling during monitoring system installation
Optional built-in DC power failure sensor, AC power failure sensor, and water sensor
2.9 Flexible power supply mode: voltage range as 85 VAC to 300 VAC, or 20 VDC to 60 VDC
