What is Firetrace?• Suppression for the
“micro-environment”• Pneumatic heat
detection • Fire suppression
system• “Total flooding” OR
“Local application” • Detection and
suppression at the ignition point

“It’s All About the ………………TUBE”
• Linear, pneumatic flame detection• Bursts at 212°F (100°C)• Tubing can be the detector & the piping
network • Tubing is durable and flexible• Tubing is not conductive or corrosive• Good for harsh chemical environments

Max 3.3 ft / layer
• Tubing is used as a detector and delivery of agent from cylinder
• Valve is a X-over only to allow for connection of the tubing to cylinder
• 4 ports on this valve for gauge, P/S, Ball Valve and cylinder
• Discharge time is limited due to the x-sectional area of the ball valve orifice.
Direct Low Pressure (DLP) System

OPTIONS
PRESSURE SWITCH
• Monitors pressure in the tubing and in cylinder
• Can use one on cylinder and as many as needed on tubing network
• Used for:• Building alarm tie-in• Power lock-out or shunt trip• Fan/damper control• Auxiliary controls
