enables on-the-spot operation of the extinguishing SECTION
–
it is possible to have four B3Q440 control consoles each with identical functions
–
monitored for open line and for equipment presence
–
separate supply and data lines (however, they can be run in the same cable)
–
individual stub lines to each B3Q440 and parallel branching permissible
–
twisted cable required (data line)
–
Max. length of line between E3G080 and B3Q440 600m (0.8 mm wire gauge)
–
with several B3Q440s on the same stub line, the line will be correspondingly
–
shorter –> see connection page158)
Setting parameters
With each B3Q440 control console, the device address must be set via the DIP
switch "S3" (for details –> see B3Q440 page 238)
Purpose
In systems in which several extinguishing SECTIONS have common reserves of
extinguishing agent, several E3G080 can be interlinked. This prevents the simul-
taneous release of extinguishing agent in several extinguishing SECTIONS.
Function
As soon as voltage 0V is applied to terminal 20, activation of extinguishing for all
the E3G080 concerned is blocked and 'Main valve' is activated. Within a group of
interlinked E3G080s, the first E3G080 activated blocks the rest.
Interlinking of several E3G080s
To interlink several E3G080s, terminal 20 must be connected to all E3G080. The
main valve can therefore be connected to any E3G080, even if the appropriate
E3G080 is in emergency operation.
