my brother just got a hazer, we were fire alarm testing and it set off our fire alarm
but that was right under it, with the hazer aiming at it

Hi,
Just a thought. I have a contract doing the electronics and Technical events for a resonably large events centre... here in NZ..liek Theatre, Auditoriums, Conference rooms etc etc.
We have the ability and regularly (like most weeks) "isolate" a particular area.. we have also "event mode" which will give warnings to duty staff but not sound the alarms for a pre-determined period.
Some of our shows, like the Ten Tenors etc use haze, smoke etc without this isolation option, this would not be possible.
Suggest you contact the Venue Tech manager and see if they have this function available. Sometimes there is a fee as there has to be someone 'on gaurd' during such an isolation.
Cheers

I once did a show for my cousin and her kids in a hotel room. I was concerned that my fog machine would set off the smoke alarm, so we covered the smoke detector in the room with a wet towel and were just fine.
Not sure that such a remedy would go over really well for a comercial gig though! Maybe you could contact the local fire marshal and ask him for advice...
As for a hazer not setting off the smoke alarm - don't bet on it! Even oil-and-compressor-based hazers can trigger an alarm. It's true that heat-based cracking units (foggers or hazers) have a better chance of triggering the alarm, but I've heard of DF50 units setting of smoke detectors before.

In my former life (one which I enjoyed much more!) I was the Stage Manager / Lighting Designer for a couple theatres. We had all sorts of shows come through those venues... A lot of them used standard glycerol smoke machines and CO2 smoke machines. Never had a problem with either of them tripping the smoke alarms at either venue. And sometimes the smoke machine operators got a bit carried away and it was so thick you couldnt see your hand in front of your face. Hehe.
We never used hazer's, so I cannot comment on them.
I believe both venues used standard ionization based smoke detectors. It's entirely possible that optical based detectors could be more sensitive to smoke/fog, especially if it's laid in pretty thick...

Thanks for all the replies...
I finally got to see the venue and they have an optical and heat sensing fire alarm. Apparently they can't disable the room and can't disable either function of the alarm...
So I got my water based hazer and glycerole based fogger and filled the room with really thick smoke, both running flat out... And guess what?
No alarms were triggered
Now I am a happy man, it's going to be one helll of a party as I am doing the music lights and lasers.... What could be better than a night of your favourite tunes and your favourite hobby all rolled into one?

BTW: Since we are on the topic. And you will laugh at Floridas stupidity on the issue but its a law.
The state of Florida requires one fire extinguisher per smoke machine right next to each machine regardless of output or if it is a hazer or smoke machine. Not because it sets off alarms, but because it produces "smoke". You know what they say, where there is smoke, theres fire. I had a fire marshal almost shut down an event because of it.
And since we are on the topic of Florida and dumbness. A certified Florida electrician must be present at all times a laser is present, to plug up, unplug and stand by the thing while its on. Even if the laser simply plugs up to a 110v circuit.
I forgot to mention this to people involved with FLEM but it applies to commercial and private events. The fire marshal was nice enough to show me both of them in the books so I know its true.
Does that mean I need to become an electrcian fpr the projector next to me?![]()
