5.6 Edit
This option is used to enter device location messages and to enter the company name of the
installation. Text editing must be done using either the PC download facility or special
keyboard.
WARNING: We strongly recommend that no text editing should be attempted without the
use of the PC down-load facility due to the extensive range of options available. However, if
direct panel programming is unavoidable, a separate document entitled “Programming the
Nexus 1-8 Loop Analogue Addressable Control Panel Without a PC” is available.
5.7 Configure Loop
At Step 4 within the Engineer’s Menu (see Section 5.3 above), select 4:CONFIGURE LOOP.
Then follow on-screen instructions.
All devices on a loop must be configured using this option in order for the panel to respond to
these devices.
The control panel is automatically searching the detection loop circuit and noting the type of
devices at the various addresses. The process takes approximately 16 seconds to complete and
provides the following report:
