Fire detection, false alarm caused by liquid spray

[David Rooney]

BSI BS 6266 Code of practice for fire protection for electronic equipment installations

This is not an "electronic equipment installation" (i.e. it's not an IT room).

7273-1 : 2006 should apply.

If its that critical I would have thought an aspirating system would have been more approriate for very early warning. This could be tied in to a coincidence system or simply used as a stand alone system.

A really radical thought might be to install a water detection system (if suitable for the liquid obviously) that could be used to disable the extinguishant release if activated first....
