I am currently looking for a hazer (in the sub-1000 dollar range) to put in to the long-term improvements proposal that I'm working on right now for an on-campus venue. The only trick is that there's a particulate detector, that cannot be turned off, above the stage (10' ceiling). We set the alarm off with a Le Maitre G150 (we own two) yesterday afternoon when testing, but we did not set it off when the room was pretty much filled with haze from a Le Maitre Neutron hazer (which the visiting LD brought in), but most of the haze stayed below the detector (lucky for us). We now know that the G150s are useless in the venue, even though they were a part of the original install! I'm looking at the Le Maitre Radiance hazer, and I want to know what experiences people have had with the Radiance and particulate detection fire alarm systems. If I run it at low output, just enough to keep the beams from my scanners visible, will it set off the system? The rest of the upgrade package includes 4 Vision Scan 250s, 20 Chauvet LEDsplash 2s, an NSI 7500 series board (either 24 or 32) to complement the MLC16D that's already there, and an opto-iso and cabling for the upgrade. Also, two new pieces of uni-strut to hang the new lights on.
