FIRE SUPPRESSANT SYSTEM- FM-200
FM200 fire suppression works hand-in-hand with state-of-the-art detection to identify and extinguish a fire hazard, long before substantial fire damage can occur. FM-200 does not leave harmful or messy residues that could damage delicate electronic and data processing equipment.
FM-200 reacts quickly at low concentrations to eliminate a fire. In normally occupied areas, people can breathe FM-200 at extinguishing concentrations without fear as it is used as a propellant in inhalers for asthmatic patients.
IVORY SYSTEMS is offering Hygood FM-200 Fire Suppression system with detection system manufactured by GENTS UK.
Solution Overview
FM-200® is a clean, safe fire-fighting agent for use in total flooding automatic extinguishing systems. It is intended as a long-term replacement for Halon 1301 and, whilst maintaining the excellent fire suppression properties of Halon, has none of the environmental problems. Storage and distribution requirements are similar to Halon and the majority of system components are identical. However, FM-200® is not a direct replacement for existing Halon 1301 installations due to the difference in agent quantity and discharge characteristics. The FM-200® design concentration for ‘normal’ risks is 7.17%, and therefore requires approximately 60% additional storage capacity over that required for Halon in the same area.
Design Consideration
The Hygood FM-200 system is designed such that a detection system sees the fire and causes the suppression system to actuate and extinguishes or suppresses the fire.
The system components and their description are as follows
Control Panel
A microprocessor-based system, that allows continuous monitoring of data from sensors.
Sensing Devices
The sensing devices are divided into smoke detectors and heat detectors. They are sensors which detect the presence of smoke or heat in a particular enclosure and sends back signal to the control panel. Detection will be achieved with a combination of Optical and Ionisation detectors. This combination is to enable the system detect the different kinds of fire namely fast burning and smouldering fires. It also has the advantage of early warning and precise identification of the source of fire. The two smoke detectors work with a double-knock principle, which allows it to identify false alarm. Before the discharge of the gas, one detector detects fire while the other confirms the true presence of the fire before triggering the gas.
Alarm Devices
These are units for alerting the occupants of a room on the outbreak of fire. A sounder with an audible output sound is used along side a Flasher which produces a visual alert for occupants who may not hear the sound from the Sounder.
Extinguishing Devices
In case of a fire outbreak, an automatic fire alarm system will automatically activate an extinguishing system thus minimising loss. The FM-200 gas will automatically discharge on confirmation of fire from the sensors. Other components of the extinguishing part are:
- FM-200 Gas Cylinder
- Nozzles
- Actuators(pneumatic & manual)
- Pilot hose.
Advantages of FM-200 System
- Effective: No other gaseous suppressant has been more rigorously tested and proven. FM-200 has been proved to be an effective, rapid acting, fire suppressing agent available today.
- Reliable: with a rapid response time of time, you can be sure that you are adequately protected.
- Low Maintenance Cost: Sensors come with a unique disposable chamber that simplifies and reduces the cost of maintenance.
- Less Space required: when space is at a premium, FM-200 is the right choice.
- Time Saving: FM-200 systems are engineered to reach minimum design concentration in 10 seconds or less. When high-value assets are at risk, every second counts. Losses can range from being virtually non-existent to catastrophic.
Re-fill Station
The Fill Station is a reservoir of FM 200 gas, which we put in place to meet our customers’ needs in this area. This has enabled us to overcome the initial challenge of the logistics involved in the importation of filled cylinder and in event of gas discharge, the cylinder can easily be refilled which has saved us the risk of having the server room/IT room unprotected against fire hazards for months.
Further to this, three standby vehicles assigned to the team to deliver the gas within the response time.
