NOTICE
Failure of the electrical connection
Damage to the screw terminals or contact problems may lead to faults in the
electrical connection. If the cable cross-sections you want to connect to the radio
gateway are larger than 1.5 mm², the screw terminals may be damaged or
contact problems may arise.
Use the connection terminal DBZ1190-AB for cables with a diameter of
1.5...2.5 mm².
Obtain a corresponding terminal from the customer for even larger cross-
sections. The terminal can be positioned inside the housing.
The radio cell is in battery mode.
The detector line cable has a wire diameter of 0.2...1.5 mm².
The detector line terminal strip is not inserted.
The 2-pin terminal strip must not be connected.
1. Wire the detector line terminal strip in accordance with the required topology.
Do not insert the detector line terminal strip until the radio cell has been
commissioned and is about to be connected to the detector line.
2. Switch the detector line off.
3. Connect the terminal strip to the radio gateway.
4. Switch the detector line on.
5. Snap the housing cover on and screw it down tight.
The radio cell is now set up and ready for commissioning via the control panel.
