Grinnell G-Fire Piping & couplings Grinnell G-Fire delivers quality grooved piping solutions for a full range of fire applications. The products offer piping and cost-effective tools for joining pipe compared with traditional welding methods. Special Design Cabinets The Tyco Model DV-5 Red-E Cabinet is a pre-assembled fire protection valve package enclosed within a freestanding cabinet designed to occupy minimal floor space and an aesthetically pleasing enclosure. The entire package is pre-wired and the water inlet and outlets to the valve riser are grooved to ensure minimal installation time. Detectors The MZX SensorLaser MZX The Zettler brand provides world class fire detection systems built on MZX Technology platforms. DV-5 TYCO Remote-Resetting, Pressure-Reducing Model DV-5 Deluge Valves are quickopening, hydraulically operated, differential-type valves designed for fire protection system service. System outlet pressure is determined by the Pilot Valve. When the valve is activated, in response to Electric Detection, the Waterway Diaphragm controls downstream pressure.
TN-25 Tunnel Protection The Tyco TN-25 tunnel fire protection system is a solution which is specifically engineered for fire protection challenges in tunnels. The improved coverage area per water spray nozzle minimises the total number of nozzles required, for instance, the coverage area of each TN-25 Nozzle is 400 ft2 (30m2), compared to a typical water spray nozzle of only 64ft2 (6m2). The nozzle s greater stream diameter results in larger water droplets, ensuring water is effectively delivered to penetrate plume and reach fuel faster, resulting in efficient wetting and cooling of fuel and tunnel surfaces. The extended coverage spray pattern is scarcely affected by obstruction as the spray pattern is designed to reach the top of the truck at the far wall. Comparison of Several System Types System: High Pressure Water Mist water mist: The Model TN-25 requires only a single pipe to protect up to 50 ft (15m) of tunnel width, with the nozzles installed with a back-to-back configuration; minimal fittings and couplings are required for fewer installed nozzles reducing installation time and materials. Easy integrated maintenance and performance testing means that piping can be flushed at regular intervals be discharging deluge zones. Valve cabinets can be customized for unique tunnel installations. Standard pressure reducing and remote re-setting deluge valves are available.

From detection to suppression, Tyco s technologically advanced Tunnel Fire Protection Solutions have been tested and approved by industry standards to ensure efficient, effective protection every time. Detection The MZX SensorLaser. The Zettler brand provides world class fire detection systems built on MZX Technology platforms. The MZX SensorLaser Plus is ideal for use in areas that are hard or impossible to access after installation, e.g. false floors, since maintenance and troubleshooting can be carried out from the control unit. The fibre optic sensor cable itself is maintenance-free and, thanks to its particularly robust characteristics, offers a high level of security against false alarms. The sensor cable is insensitive to dust, dirt, moisture, high temperatures (up to approx. 90 C), pressure and the action of vibration and wind as well as corrosive atmospheres. Because of its purely passive, optical analysis process, the MZX SensorLaser Plus is even immune from electromagnetic interference caused by generators, energy routes, cables or motors.
