Fire detection and extinguishing system

The Firepro extinguishing system is based on the use of a fire suppression agent, a potassium-carbonate aerosol spray developed from a solid mixture defined as «compound», contained in steel dispensers fitted with grilles for discharging into the environment and referred to as «aerosol spray generators». The ultra-fine dispersal, in a protected space, of solid particles suspended in an inert gas makes it possible to extinguish fires. The extinguishing mechanism is the interruption of autocatalysis and consists of the chemical inhibition of combustion at a molecular level, without it leading to any reduction in the environment’s oxygen content.

Monitoring system with touch screen terminal

The cabinet is fitted with a system for monitoring vital parameters. Data are collected and made available via a touch screen monitor with a simple and intuitive user interface. In a critical alarm situation, the monitoring system sends an e-mail or SMS and records the event in a log. The monitoring interface, through which it is possible to interrogate, change certain operating parameters, consult logs etc., is remotely accessible via an Internet browser.

Parameters monitored:

• Cabinet’s temperatures on the front and back, and humidity
• Air conditioning control unit
• Status of fire detection and extinguishing system
• Door opening
• UPS status

UPS

The RAM batt line’s UPS make careful PWM management of the fans possible, in order to minimize power consumption and reduce the system’s noisiness, to improve its comfort. Moreover, management of the UPS batteries has been optimised with charging curves based on the temperature and continuous dynamic control of their integrity.

Air conditioner

The RAM klima air conditioner is designed for cooling IT cabinets. Its use makes it possible to cool and dehumidify the air inside the cabinet thus preventing the equipment installed from malfunctioning. The air conditioner is fitted with an adjustable intervention thermostat which is controlled from the Net One touch screen terminal. The refrigeration circuit only begins operating when a pre-set temperature has been reached. In the 4000 W version the air conditioning unit draws warm air from the servers from the rear part of the cabinet and returns it cooled to the front of the cabinet throughout the cabinet’s entire height.
