General Monitor is pleased to announce the introduction of the IR5500 long range configuration.

Like the standard model, the long range system is performance approved under FM 3265, EN 50241-1, -2, and IEC 60079-29-4 on both LEL-m and ppm-m scales.

The detector covers a distance of 50 to 150m for LEL-m monitoring and 80 to 150m for ppm-m applications, providing superior detection for a wide range of applications.

Accurate and fast alignment of the source and receiver is fast and easy with a long range alignment kit (329082-1).

The following link shows in a video the specific steps to take when aligning the IR5500 through the 4 Pillars of Alignment, along with some insightful tips: http://bit.ly/IR5500demo

  1. Clear
  2. Measure
  3. Source
  4. Receiver

 

Response time is a key measure of a gas detector’s performance and strong influencer of customer preference.

Fast and early detection of unignited escapes of flammable or toxic gas allows automated fire and gas systems to launch protective responses that prevent incidents from escalating.

Among flammable gas detectors, open path IR devices have among the fastest responses. According to FM 6325 (2005), for instance, an open path detector must reach a measured value of 90% of the final reading of the standard test gas integral concentration in no more than 10sec. Not surprisingly, most commercial models have so-called T90 response times in the range of 2 to 5 sec.

Recently General Monitors obtained approval from regulatory agencies for a new specification for T90 response time. In consequence, the measure decreased from the previously published value of less than 5 seconds to that of 3 seconds or less, a 40% improvement.

The IR5500’s revised T90 is one of the shortest of those of several open path IR models in the market.
