CIE-A-200 Control Panel Engineering and Commissioning Manual

Good Practice
The following suggestions are good practice if carried out during commissioning, and may help avoid
common problems at a later date. The Fike Safety Technology Technical Support department may be
unable to assist if the information is unavailable, and the guidelines not followed.
Number of Devices
Make a clear note in the control panel back box in a conspicuous position of the number of devices on the
system.
In the event of any future visits to site it will be clear how many devices are expected if the system is
initialised. Without knowing this it is not possible to be sure that all devices have initialised correctly.
Label the Loop Ends
Make a clear note on the loop cables attached to the terminal block to show
LOOP END 1
and
LOOP END 2
.
Thus, if the addressable device loop is reversed for any reason it will be plainly visible from the labels.
Note the Loop Readings
Make a clear note in the control panel back box of the loop continuity and insulation resistance readings,
including those for the screen and mains earth.
These are then available for fault finding at a later date, ie.
+ -- SCRN
LOOP END 1
+ -- SCRN
LOOP END 2
