Type of detector in EDG room
Type of detector in EDG room
(OP)
Do the IEC Standards (or fire standards) mention which type of detector should be in the Emergency diesel generator (EDG) room. Should it be Heat or Smoke Detector .There is confusion as earlier we had smoke detectors & it gets activated when EDG starts as some smoke is also generating in the process.Then we replaced it to heat.

Good luck.

The insurance company of the installation may also have a view, especially if the set is in a basement, for example.
Might be a good case to find a consultant with experience of this.
RE: Type of detector in EDG room
Smoke detectors, such as they are, are generally life safety devices to protect personnel against certain hazards and the occasional over alarming is completely acceptable. Heat and flame detectors are generally to protect equipment/process/structure against certain hazards where the life safety personnel protection is unsuitable or inadequate for some reason. If a misoperating smoke detector can create greater hazards, can easily happen around this type of equipment, and the general public is not in the area, accommodations can generally be mad.
If forced into use of a smoke detector where not truly suitable for the conditions, perhaps the authorities would accept alarming from the smoke detector but allowing the heat or flame detector for equipment shut down.

BUT, rate of rise detectors are not suitable everywhere. They may alarm at temperatures below freezing if installed in a cold storage room and are subjected to a rapid temperature rise if a door is left open. Say from minus 20 degrees to minus 5 degrees.
Some places where rate of rise detectors are NOT USED are;
Cold storage rooms.
Elevator shafts.
Near doorways where they may be subject to rapid temperature changes,
Boiler rooms.
Engine rooms (generator rooms).
