3 U rack extinguishing system

Detection-Active

DET-AC 1.4 FM200



By means of the Rittal rack extinguishing system

Detection-Active (DET-AC) individual racks or series of

racks (up to 4 bayed racks) can be monitored and

extinguished (can also be used for bayed enclosure

suites equipped with Rittal cooling system LCP). The

system is fitted with a multistage smoke analysing

suction system: When sensor 1 detects smoke, alarm is

released, if sensor 2 detects smoke, extinguishing

action is released. Beyond that, the smoke suction

system with its tube system allows to take air samples

behind each server (even when they are distributed over

several racks) and to analyse these. By means of this

distributing system also the fire extinguishing gas is

fed to the individual racks. The electronics can act

directly on the ventilation systems installed in the

racks or the power supply to the installed hardware and

can switch these off. By the automatic system

deactivation the defective rack can optionally be

de-energised and spreading of the fire prevented in

this way.



For optimum function of the rack extinguishing system

the rack must always be of closed, tight construction.



Optionally the pre-alarm, malfunctions, or

extinguishing action can be signalled directly via the

Rittal CMC-TC system through the network

(SNMP/SMS/Email/etc.).
