how do I patch a radiance ultratec hazer to etc element lightboard. They want to eventually control the hazer with submasters - one for haze and the other for fan

the element has channel fader and subs. if the want to use the channel faders you would have to patch two dimmers, patch one to the hazer's start address and one to the address + 1.

with subs you don't have to patch as dimmers but of course still can. but from a data visibility point of view it's probably to patch as dimmers as well.

when you patch a hazer as dimmer (and also make use of a grand master fader) you want to think about if the grand master should influence the hazer or not, and use the attribute GM Excempt in patch accordingly.

last but not least: i prefer hazers not recorded into cues. that's why i set hazer subs to Exclude:Record so they don't get accidentally get recorded into cues. i also like to have a haze Inhibit sub somewhere. e verybody using the console is taught to always have that inhibit at 0 until they get clearance (e.g. smoke detectors) and also but the inhibit back to 0 when they leave the board.

Sorry, I need clarification - is a haze inhibit sub a separate, third sub created to turn the haze/fan to zero? Is that not accomplished by sliding the fader on the haze sub and the fan sub down to the zero mark?

you're absolutely right, the inhibit sub would be an additinal fader. i like it because the fire deparment's fee for false alarms is just too high... so i like the fact that it's not enough to just come to the console and move the haze fader up, but rather i have to think of the additional safety precaution as well and move the inhibit to allow haze.

the inhibit at 0 would also avoid problems if someone by mistake recorded haze values into a cue. you want to do a rehearsal without haze and think "haze fader is at 0, nothing will happen". until you hit the cue that has haze values recorded by mistake.
with a haze inhib you can be sure that no cue or other sub can activate the hazer.

if you want to go even further, you could make your haze subs Shielded. that means the hazer can only be controlled from those shielded subs. it cannot be recorded into a cue, i cannot be controlled manually (type the channel number and roll the wheel).

As always, your help and timely response is very much appreciated!
