產(chǎn)品名稱：GMI 4500氣體報警控制系統(tǒng)

When you’re looking to monitor a medium to large application of up to 40 potential gas leak points, you need an system that will respond quickly, is tried, tested and proven in a wide variety of industries, and more importantly; has a history of being reliable and cost effective.

With that criteria in mind, GMI produced the 4500, an advanced fixed detection system which will quickly monitor any combination of flammable and toxic gasses, oxygen and fire. Typically these applications include water utilities, petrochemical industry, boiler rooms, underground car parks, landfill sites, building management systems and the oil industry.

Its traditional design allows all gas and operating values to be displayed on the LCD using the buttons on the inbuilt keypad.

特性：
 

• Up to 40 Detection Points per 19'' rack
• Relays to enable interfacing with your existing equipment/systems.
• Easily calibrated
• LCD displaying system status
• LED for individual A1,A2 and Fault Alarm
