    Product Description The SharpEye IR3 Long Range Fire simulator 20/20-310 is designed specifically for use with SharpEye IR3 flame detectors. The Fire Simulator emits IR radiation in a unique sequential pattern corresponding to and recognizable by the IR3 detector as fire. This allows the IR3 detectors to be tested under simulated fire conditions without the associated risks of an open flame.

  • Page 55: Figure 17: Mini Ir3 Detector Target Point

    Follow these instructions to simulate a fire: 1. Aim the Fire Simulator towards the detector’s “Target Point”. 2. For testing keep a distance of at least 50cm (20 inches) from the detector. 3. Press the operation button once. Fire simulation will last for 20 seconds.
