RCF is showcasing its DXT series of emergency evacuation systems at ISE 2016, which have been upgraded with a number of new components to boost system architecture.
On show will be the EN54-16 compliant DXT 3000, DXT 7000 and DXT 9000 systems, with the DXT 3000 and 9000 now equipped with several new components. Upgrades on the DXT 9000 include the MU 9186R Master Unit with integrated router and RP 9600 Data Repeater.
Features of the MU 9186R include Maximum connection of eight systems, giving a total network of 256 units; Twin LAN ports for Digital Audio In (1 channel from external source), and Out (2 channels up to 4 sub-systems or 1 channel from 5 to 8 sub-systems).
RCF R&D project manager commented: “These components allow system scalability to be increased, opening it up to large scale applications, such as multi-building environments.”
Completing the new DXT 9000 system components, the IN 9000 Integrity Network Emergency Console emergency console is designed as an interface to provide a fully analogue redundancy in the event of interruption by the RCF-Flexicomm bus.
The console is equipped with a monitored fireman’s microphone with PTT button, and can be powered by 24V to 48V external supply providing at least 20W output power.
The DXT 3000 has been upgraded with the new MG 3006 Monitored GPI Board, which is an accessory that monitors emergency system GPI, to enable detection and reporting of any open line or short circuit in the signal path between the DXT 3000 and other alarm devices, such as alarm buttons. It can trigger both a general and a zone evac event from alarm devices and send the reset command, working exactly as a fire alarm system.
A maximum of four BM 3804 can be connected to the master unit, interlocked on a single chain, and the first one (with eight BE 3806 connected) is powered by the MX 3250. Up to eight BE 3806 can be connected to each BM 3804 in the chain — and each extension can select and manage each zone of a specific MX 3250 unit. Local paging for non-emergency purposes is possible by connecting a BM 3022 console to each unit.
The DXT 3000 evacuation system was installed in the pavilions of Austria, Vietnam, Azerbaijan, Moldavia and Principality of Monaco at the Expo 2015.
