System Power Supply - Detnov CMD-501 Manuel D'installation Et Mode D'emploi

It is imperative to use the holes marked in the box for connecting the power supply
wires and those from the areas to the terminal block. Use a "crown" drill bit to perforate
the box and insert the PG11 type gland.
Each area module includes an 11-pole connector for connecting:
• First extraction relay.
• Second extraction relay.
• Line input.
• Alarm relay.
The line detector connections are shown in the following drawing.
Once you have made all the connections described above, connect the mains power
supply by activating the bipolar magnetothermic switch and check the system.
• Once you have connected the power supply the station will check the system,
calculating the detectors that are connected to the lines and showing them on the
display for 5 seconds. If there is any kind of fault, it will be shown on the display.
• Also, pressing the test key will check the displays and all the system indicators are
working correctly. It will also show the number of detectors installed in the area and,
finally, the display will show any faults there may be in the installation.
• Once you have done this, all the indicator lights of the station must be off, except the
AUTO LED on the keypad. The reading taken by the CO detectors associated with
the area will appear on the module display. To start up the extraction outputs, use key
B to activate the desired state, ON or AUTO.
The system is checked based on the following points:
• Verify that when you cause an alarm, the alarm relay is activated.
