switch, the message “Blocking by door cont.” is generated and the yellow LEDs
(Fig. 40/1+3) lit up.

rear side of the system, the door contact
switch is deactivated. The message
“Failure door contact” is also shown in the
display.

vate the system using the upper [Reset]
button (Fig. 40/2).
The check must be performed for each of the door contact switches that are
installed.
