1INTRODUCTION
The EXXFIRE® 750TW/1500TW/2250TW is an extinguishing unit that detects and extinguishes
fires in small, protected spaces, such as server racks and electrical cabinets.
Upon detection of a fire, nitrogen gas is released from the unit. The nitrogen gas dilutes the oxygen
level within the enclosure, and consequently suppresses the fire. The TW version of the systems are
using a thermal wire to detect fire. The thermal wire will cause a short once a specified temperature
has been reached.

2PRODUCT DESCRIPTION
EXXFIRE®750TW/1500TW/2250TW
The EXXFIRE® 750TW/1500TW/2250TW is a unit that is used to detect and extinguish fires in
small, protected spaces, such as server racks and electrical cabinets. The EXXFIRE®
750TW/1500TW/2250TW is equipped with:
•One, two or three cool gas generators to release nitrogen gas
•Linear heat sensing cable to detect fire
•Software to ensure robust decision making
•Electronics for configuration settings and status outputs
•Inputs for manual activation button (MAB) and door switch (DSW)
•Back-up battery
Upon detection of a fire event, nitrogen gas is released from a cool gas generator (CGG). The
nitrogen gas dilutes the oxygen level within the protected space, and consequently suppresses the
fire. This is in line with common practice using compressed IG-100, or other clean agents in higher
hazard class A fires at 20 oC. If normal class A fires are taken into consideration the systems can
protect a larger volume (see NFPA 2001 for the exact calculation). For class B fires a single
generator produces 1.16 m3.
