monitoring.

Mounting, removing and wiring of control panel
The control panel is wired straight from the electrical connection box. The control panel can
also be connected in series with a CO
2
sensor or another control panel. (See External
electrical connections on page 8).
Control panel addresses
If two or more control panels are connected to the system, the addresses of the control panels
need to be changed.
E.g. 3 control panels.
• Connect the first control panel to the unit and change its address to 3.
• Connect the second control panel to the unit and change its address to 2.
• Connect the third control panel and make sure that its address is 1.
If control panels have the same address, they go to bus fault state. In this case, remove one of the control panels
and change the address of the other panel. The above mentioned situation can arise in connection with the later
installation of an additional control panel.
