Applications:• Road and railway tunnels● Cable routes, bus ducts and data centers● Storage facilities and warehouses ● Nuclear and other special hazard facilities● Commercial Buildings and Parking Garages

Features:● Immune to electromagnetic noise (EMI), dirt,

dust and humidity● Pinpoints exact location, size and spread of fire

events● Cost effective, gathers thousands of measure-

ments in a single sensor over long distances● Easy to install and integrate into fire management systems ● No maintenance or individual calibration required for each sensing point being measured● System life expectancy of 30 years or more based on mean-time-between-failure (MTBF)

statistical field analysis ● Intrinsically safe sensor for hazardous environments● Eliminates power and communication cabling to operate individual/multiple sensors● Alleviates the need to know which exact locations need to be monitored for each application● Wide range of packaging techniques for harsh environments● Stand-alone or system integrated operation

The alarm criteria in hundreds of zones along the same sensor cable are user configurable, which minimizesthe risk of nuisance alarms in environments with dynamic temperature ranges. The system can be pro-grammed to interact with surveillance and suppression systems to ensure an accurate and effective response.

Marmon Engineered Solutions provides fire detection for harsh, hazardous environments, basedon fiber optic Linear Heat Detection. These systems offer maximum asset protection with lowoverall installation and operating costs, in even the most extreme conditions.
