DISPLAY MESSAGES

• " ." (bottom-right line of the display)
Warn
This indicates that the module line has detected the first programmed level. This level is just of information
because it has not got manoeuvre output.
• " " (bottom-right line of the display)
Preala
• " " (top-right of the display)
Ven1
This indicates that the module line has detected the programmed prealarm level and the electrovalves of area
are activated.
• " " (bottom-right line of the display)

This indicates that the module line has detected the programmed alarm level.
• " " (top-right line of the display)
Goff
This indicates that the module line has detected the programmed alarm level and that the electrovalve has

11. SYSTEM CONNECTION -all standards-
1. Press ON/OFF to connect the module line.
The message "Detector search" will be shown on the top line of the display, and the bottom line will show the
number of detectors connected (*) or detectors not connected ( - ).
Example: 1 2 3 -- - - - - - - 11 12 13 - - 16
* Detector detected
When finished, the top line of the display will show the number of detectors detected (7) and, sequentially, the bottom
line will show the number asigned to each detector: 1, 2, 3, 11...
Next, the display will show the number of programmed detection groups: 1, 2 or 4 groups, depending on the standard.
Finally, the Module Line will be connected.
If any of the groups have not been settled down correctly or can not communicate with the module line, the display
will show the messages "Group Number" and "Fau", also an acoustic signal will go off indicating the error. If none of
the groups responds, the module line will be automatically disconnected -OFF position-. Check the connections, the
programming of the module line, the detectors and repeat the process.

12. CHANGING THE SENSOR

When the sensor can not be calibrated or it seems to be unstable, it will be necessary to replace it. Follow these steps
to do so:
1. Disconnect the module line where the detector is connected to.
2. Remove the four screws from the detector housing.
3. Disconnect the CN1 connector.
