Just a thought.......

We have had previous success with the following
methods:

1.  Install a smoke detector within this space for an
early warning alarm signal prior to the activation of
the 360 degree head, OR

2. Install an air sampling system and control panel
for the room, along with the 360 degree head.  The air
sampling system (AnaLaser, VESDA, etc)is a very
sensitive detection system and gives an alarm
condition way far earlier than the common smoke or
heat detector. When we used this method, our
sprink-head temperature was no higher than 212
degrees.
