Fault Indication
This fault indication without display of any device no. appears only on the repeater
panel. It means, that no call of the master reaches the controller of the indication- /
control module in the repeater panel. Therefore no other faults can be displayed.
Please check the following:
• Check setting of rotary switch at indication- / control module in smoke detection
panel. The adjusted no. determines the no. of called slaves.
• Check setting of rotary switch at indication- / control module in repeater panel. The
adjusted no. determines the address-no. of the repeater panel.
• Ensure, that the address-no. of the repeater panel is not assigned to another
component.
• Check the fuses on the adapter – pcb of the repeater panel.
• Ensure correct bus-cable connection to the repeater panel. Note: In most cases the
cable between smoke detection panel and repeater panel is lead through a cable
connection box. This bears the risk of a mix-up of the 4 wires. If you are not sure,
whether the connection is correct, please proceed as follows:
Go to the smoke detection panel and disconnect the wires to terminal nos. 19/20
from the cable which connects the repeater panel. Switch on power supply. Go to
the repeater panel and find out the wires which carry 24V ( 20 – 28 V ). Connect
the plus-pole to terminal no.17 and the minus-pole to terminal no.18 in the repeater
panel. When power is on, the green lamp of the repeater panel must be lighted now.
Now connect the remaining wires to terminal nos. 19/20. If the a.m. fault indication
is still present, please exchange the wires at terminal nos. 19/20. Now the repeater
panel should be connected to the master.
Fault Indication
This fault indication shows the address of the component, which is not detected by the
master or by the repeater panel. Please check the following:
• Check setting of rotary switch at indication- / control module in smoke detection
panel. The adjusted no. determines the no. of called slaves.
• Check the setting of the rotary switch of the component, which shall have the
address no. "x".
• Ensure that this address no. is not assigned to any other component.
• Check the wire connections of the bus-cable.
• Check fuses of the component with address-no. "x".
