5.6.2 Numbering the control modules
WARNING
The renumbering of an input or relay module (by repositioning the jumper on the
module) after configuring the control unit can cause alarms to not be activated as
desired.
► If an input or relay module is renumbered, configure the control unit to ensure
that the alarms are activated as desired.
Input modules
Place a jumper on the appropriate "Module no." terminals on the input module to
determine the channel numbers in the REGARD
®
3900 system.
When numbering the input module, the following should be noted:
– Each input module within the control unit must have another module number (1
to 4).
– If only one module is installed, assign the number 1.
– All modules must be numbered consecutively, otherwise problems may occur
during the configuration of the system.
Relay modules
Place a jumper on the appropriate "Relays" terminals on the relay module to
determine the relay numbers in the REGARD
®
3900 system.
When numbering the relay module, the following should be noted:
– If only one relay module is installed, place the jumper at position 1–8.
– If a second relay module is installed, place the jumper at position 9–16.
