Fire

[alarm man]

id go for ror heats,if smokes are being set off beams will too if the steam is causing the problem.you could go down the vesda route but will mean ripping the system out and starting again,no doubt at your company's expence

I take your firm didn't do the design for the Fire Alarm circuit

If the design company specified what you should put in and you did it to spec then sorry your job is done -if it does not work because of a problem with the wrong equipment in the spec (from the sound of it this is the case) the design company is responsible.

Throw it back at them and tell them to redesign it as their system is not working to the customers spec and it is not fit for purpose!

Then if they change the system they are responsible for meeting the costs encored, if they dont pay up then that's a claim against their PI.


As this post is now a few days old have you sorted it yet?

Vesda, or airsense can be a problem in this situation, water evapourators can help, but the filters dont really like water.
Beams are the only answer in hostile situations.

steam is not a problem for vesda and the small amount of steam which could arise in this situation would pose no problems at all.most ir beam manufactures say not suitable for areas of dust and steam..

Alarm man, see were your coming from, with the amount of steam or water when it condistates, but would wonder how much a vesda or airsense could function over a long period in such evoroments, and to what extent. The old fixed beams being a pain in the rear have now been sorted with programmable beams such as Fire beam made by my old company Lemtronics. In areas of dust or high combustion would certainly go for the fast response of vesda.

id compare vesda to a fine car,needs looking after and regular tuning for the filter and airflow,if looked after never false alarms and provides the best protection around..

Certainly would not disagree with that, air sampling has always showed a faster response time, always found it the best solution for closed cieling voids.
Just checked with vesda, Airsensense, recommended use of water traps, evapourators in high humidity so your answer is correct, vesda is suitable if well mentanained

I think most of us signed up for that reason. There are times though, especially on something of this scale and importance, where a forum is really not the answer imo.
