Portable Fire Suppression

["Christopher J. Wolff" <chris () bblabs com>]

Greetings;

I would like to protect an unattended server enclosure in a remote
location with some variety of fire suppression device.  I imagine that
some enterprising soul has invented a fire extinguisher with a nozzle
that opens at a preset temperature (i.e. exploding head).  Thank you in
advance for any advice you can provide.
