8/9/ Diversified Air Systems,Inc. Firetrace Technology Call today:

8/9/ 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

8/9/ “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

8/9/ Direct System Direct Low Pressure System

8/9/ Direct System Effects of high air velocity may impact discharge Must be careful with locating tubing … discharge is at tubing burst point Limited to 50 ft – furthest point from cylinder … system can have well over 200 ft of total tubing 1 lb / 3lb / 6lb / 12lb Clean Agent Assemblies 2.5lb and 5lb Dry Chemical Assemblies

8/9/ Commercial Name : FT 1992 Thermoplas Physical Appearance: 6mm OD red tube Change in Physical state: 194 C (381.2 F) Bulk Density :17g / meter (5.18g/ft) Dielectric Strength:(DIN 53481)kV/mm dry 40 Thermal Decomposition:Above 300 C (572 F) Temperature at Burst: psi ( psi) Characteristics of the Firetrace Detection Tubing

8/9/ The “Burst”

8/9/ 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

8/9/ DLP (Direct Low Pressure) System

8/9/ 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
