Switching detector over to collective operation
When supplied, the detector is set for operation on an FDnet/C-NET detector line.
When operating a collective detector line, the control panel normally switches the
detector to collective operation automatically.
Some collective control panels do not however automatically switch from FDnet/C-
NET operation to collective operation. In these cases, you must switch the detector
over manually. If you are not certain whether the detector is switched over
automatically, switch it manually to collective operation before installing.
The detector always switches automatically from collective operation to FDnet/C-
NET operation.
Procedure
Note the positive and negative poles.
The detector base must not be connected to the detector line.
1. Connect the detector base to a DC 12 V to 28 V source of DC voltage, e.g. a
battery, according to the connection diagram shown below. Use a screwdriver
to remove the load from the spring clip so you can slide in the wire.
2. Insert the detector unit into the detector base.
3. Wait around 15 seconds and then remove the detector unit and source of DC
voltage.
The detector is switched over to collective operation and can be connected to a
collective detector line.
