Address programming of loop elements
Loop elements can be programmed in two ways:
1. via the AUTO-addressing function of the fire detection control panel in conjunction with PARSOFT
2. with an external programming unit (FI700/PU or FI750/PU)
3.3.1
AUTO-addressing of elements
The element address of the Series FI700 and FI750 devices can be automatically assigned. The AUTO-
addressing can be started via the fire detection control panel or via PARSOFT.
There are two possibilities:
1.
Automatic creation of the parameter data, menu item [AUTO-setup] in PARSOFT or [Delete set-
tings and initialize devices] at the fire detection panel. This function deletes the existing configura-
tion of the fire detection control panel and automatically assigns addresses to the loop elements
anew, according to the installed componentries and loop elements.
2.
Automatic update of the parameter data, menu item [Initialize new devices]. This function detects
new elements on the loop, transfers them into the control panel configuration and automatically
assigns the element address.
Addressing a fully equipped loop (240 addresses) will take approximately 12 minutes. This results
from an addressing time of about 3 seconds per element.
The cable length between two loop elements must not exceed 250 metres.
The wiring is only allowed in the form of a ring. An example can be found on page 189 in Chapter
3.14: „Example for the wiring of detector circuits“.
No further loops may be connected to a loop line. All branch lines and the elements on this branch
shall be removed.
3.3.1.1 AUTO-setup – automatic addressing of all loop elements
The AUTO-setup deletes the configuration of the fire detection control panel, scans the installed com-
ponents (loop interface, conventional detector interface, fire brigade interface, …) and deletes the
addresses of the existing Series FI700 loop elements. In the next step a new address is assigned to each
loop element. This is done by polling the loop elements via terminals 1 and 2 of the loop interface.
The AUTO-setup is started via
PARSOFT
by selecting the following menu item:
[Communication] - [AUTO-setup]
Starting the AUTO-setup at the
fire detection control panel
(authorisation level 3) is done by select-
ing:
[
Parameter settings
]
[
AUTO-setup
]
[
Delete settings and initialize devices]
The next picture shows the address condition after the start of the AUTO-setup. The element addresses
have been set to 255 (factory default value).
