For Data Centers

The highly com­plex tech­nical equip­ment of data cen­ters and other IT areas, as well as the ma­ter­i­als used there, carry a par­tic­u­larly high risk of fire. Due to the high con­cen­tra­tion of en­ergy and the ma­ter­i­als used, e.g. plastics, data cen­ters present an in­creased fire risk. 

Due to ab­sent or un­pro­fes­sional cool­ing, hot spots can occur in the sys­tem, caus­ing over­heat­ing. Nu­mer­ous act­ive elec­tronic com­pon­ents, com­plex cabling in false floors and trans­ition res­ist­ances in the many cable ter­min­als en­tail a risk of short-cir­cuits, tech­nical de­fect or thermal over­load­ing. This is es­pe­cially true for the com­puter and server areas, in­clud­ing the as­so­ci­ated cli­mate brack­ets in data cen­ters. Even small or me­dium-sized server rooms and closed server cab­in­ets as part of a com­pany's in­fra­struc­ture in any sec­tor of the eco­nomy fea­ture the same fire haz­ards.

Flames, smoke, gas emis­sions, heat – fire has many fa­cets. Orena has the right fire de­tect­ors for the vari­ous areas within data cen­ters. Their sig­nals con­verge in the fire de­tec­tion and ex­tin­guish­ing con­trol panel, which is­sues an alarm to the people at risk and the fire bri­gade. In ad­di­tion, the Orena panel mon­it­ors the in­stalled fire pro­tec­tion sys­tem for proper func­tion­ing and elec­tric­ally trig­gers the ex­tin­guish­ing sys­tems.

Traditional fire alarm systems are not dedicated to data center application, there are the following prominent pain points:

1. Ordinary point-type smoke detectors are difficult to play a role
A large number of air conditioners and fans are used in the machine room, and the air flow speed is fast, and the smoke generated by the fire is difficult to gather, so that the traditional point detector alarm is slow or even unable to sense and alarm.

2. The high-sensitivity aspirated detector has many false alarms
The aspirated smoke detectors commonly used in data rooms are extremely sensitive, and are often prone to frequent false fire alarms because of dust in the air, and dust accumulation will also lead to more fault alarms.

3. Delay in extinguishing the fire
Because of the many false alarms, the fire duty personnel had to go to the scene to verify the authenticity of the fire, delaying the precious fire extinguishing disposal time at the initial stage of the fire, resulting in significant fire losses.   

Specialization, Customization, Visualization

• Visual alarm through 2-wire fire signal loop circuit, quickly confirm fire alarm, quickly extinguish fire, no fear of false alarms, avoid false spray.

• The visual fire detector is equipped with a built-in camera, integrating security and fire protection.

• An aspirating high-sensitivity fire detector is added, providing an extremely early warning and visual confirmation of fire alarms.

• Different types of fire detectors are set in different places. 

Combine local control and remote control

Construct a closed-loop fire control system featuring high reliability, high anti-interference, multi-dimensional detection, early warning, timely confirmation of fire alarms, and rapid fire extinguishing.

Fire detectors setup scheme: Classified partition protection

Based on usage functions and importance, data center applications are divided into the following four categories:

1. Core areas: Data room, UPS distribution room, battery room, set up point-type air breathing smoke detector, visual smoke/temperature detector (can be linked with air breathing detector, the first time to confirm the fire alarm), HFC-227/FM200 gas fire extinguishing system, electrical fire monitoring system

2. Rooms for supporting equipment: High-pressure water mist fire extinguishing system is used in diesel generator room and low-voltage distribution room; HFC-227/FM200 gas fire extinguishing system is used in medium voltage room and weak current access room, and ordinary point-type smoke and temperature detectors are set.

3. Attached areas: Offices, meeting rooms, underground garages, etc., adopt automatic sprinkler system, and set ordinary point-type smoke and temperature detectors.

4. Special area: Shared atrium and other tall space, set dual-band infrared flame detector, light beam smoke detector, with automatic water cannon fire extinguishing system.
