Fire in the Foundry

[prepman]

Yes that's the sort of thing I need - have you any idea of how far apart they can be? The foundry is probably 100 yards from the house and steel framed which doesn't help WiFi range.

(We've 9 smoke detectors and 1 heat detector in the farm house - all interlinked, and they make an enormous racket when triggered !)

Ah!.... so you are already part way there. Cabling would probably be your only option My furnace is just on the other side of house wall. As to temp...I don't think even near the foundry would set off the heat alarm. Hasn't so far. In the old days the electromechanical ones had 2 (bimetal?) elements. One had a damper so that if the temp came up slowly and didn't hit max then no alarm. Rapid increase set off the CO² extinguishers in the substation.

We had the same system in the substations at Longbridge, first thing you did was go into the bottle room and mechanically lockout the banks of CO2 cylinders before going into the main switch room, one day a guy who had only been half listening went in and knew he had to make the system safe so pressed the button marked "discharge"

Yes it was a bit twitchy in there even with the lockouts....fortunately I was an apprentice instrument tech on rotation. Quite interesting being with different trades. Wasn't seconded to joiners and plumbers though. Boilerhouse was like a huge adventure playground Switchgear made my mind up not to be an electrician....... only later in life trained up on 6.6KV gear (10,000BHP) as a side line.
Preferred to be only as close as the DCS was to the gear.

Computer rooms with Halon gas were the ones that scared me !

Never had a problem with ours. However, we did have a decent interlock system.

We had Halon systems on the control cabinets in the roof, I never had cause to work in one.
