Description
Technical Description – SpyGlass SG50-F-IR3 Triple IR Flame Detector
The Spyglass SG50 IR3 is the next generation of the IR3. It has been introduced to further enhance the protection and safety for these high risk and high value industries.
The Spyglass SG50 IR3 will detect fires and explosions extremely fast, thus allowing preventative action to be initiated even more rapidly and minimizing the consequences!
A Closer Look
The unmatched detection times and distances are:
- Highest immunity to false alarm
- Triple IR uses three wavelengths in the infrared spectrum from 4.0 to 5.0 μm to detect hydrocarbon fires.
- HD, or composite, video output with automatic HD video recording of events on IR3-V
- 5 selectable sensitivity levels
- Ultra-fast detection within 40 milliseconds for fireballs or explosions
- Fast flame detection, <1.5 s for standard fire up to 30 m. Option for <0.5s, in compliance with NFPA 33, available
- Optimized CO2 L option for aircraft hangars, helipads & truck loading racks available
- Detects up to 262 ft. (80m) for a 1 ft (0.1m²) n-heptane fire
- Event logger: Alarms, faults (& videos for IR3-V) are logged to non-volatile memory
- Universal outputs, 3 and 4 wire, 4-20 mA sink / source, Fire, Auxiliary and Fault Relays. RS485 port using Modbus RTU
- Built-in-Test (BIT) – Automatic and manual internal self-test of window cleanliness and the overall operation of the detector.
- HART® 7 units available – Easy configuration and diagnostic capability, including dirty optics warning for preventative maintenance needs.
- Window heater to avoid condensation and icing.
- Stainless steel tilt mount with horizontal and vertical adjustment
- SIL 2 compliant – suitable for use as part of a SIL 2 compliant safety system
