- Product description
- The active extinguisher system includes the smoke extraction system and the extinguisher unit. The smoke extraction system is identical to the smoke extraction system in the EFD III. The extinguishing process begins automatically when a main alarm is activated. For the extinguishing process, the tank is pressurised via a propellant cartridge. The extinguisher gas Novec™ 1230 evaporates at the extinguisher nozzle and is distributed in the server enclosure.

- DET-AC III Master, fire alarm and extinguisher system, active smoke extraction system, early fire detection, automatic extinguishing.
DET-AC III Master fire alarm and extinguisher system
The fire alarm and extinguisher system is able to detect and extinguish
fires at an early stage. The compact system occupies 1 U of rack space
and is designed for installation in the 19" level of closed server
enclosure systems.
An integrated fan continuously draws in air from the protected space via
a pipe system. This air passes two smoke detectors. If smoke aerosols
are detected, the high-sensitivity smoke detector triggers a pre-alarm
state. The second smoke detector triggers the main alarm and activates
the extinguishing process. The proper functioning of the smoke detectors
is monitored continuously by the evaluation and control electronics on
the control board.
The extinguishing agent used is NOVEC 1230, which is held in liquid form
in the tank. When extinguishing is activated, the tank is pressurised.
The extinguishing agent vaporises at the nozzle and spreads through the
protected space.
The extinguishing nozzle is located in the front panel of the unit. The
frame for installation of the active extinguishing system is designed as
a 19" rack module. The depth of the system is such that it can be
installed in 19" server enclosures with an internal depth > 800 mm.
The pre-assembled system can be inserted or removed without interrupting
operation of the equipment to be protected.
A CAN bus interface enables direct connection to the Rittal CMC III
system.
The fire alarm and extinguisher system has been tested by VdS
Schadensverhütung GmbH. All tests were completed with a positive result.
A USB port offers a possibility to retrieve information on operating
states and events, as well as to perform various settings. To this end,
a special maintenance program is made available for use by appropriately
trained personnel.
The commissioning must be carried out by Rittal.
