5.6Edit

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.
