Z-loop functional tests
Connect all the loops to the panel. Power-up the panel, and allow the panel to go through
the self-diagnostics, device acceptance, and automatic calibration. Then go into the Setup|
Points|Accept Points menu, and manually accept all devices online. Then carry out the
following checks.
Identify the device addresses on each loop that are [1] the closest to the panel, [2] the
furthest from the panel (ie, near the end of the Z-loop), and [3] about halfway along the Z-
loop.
In the maintenance|reports to screen|point analogues menu, check that the first analogue
value (the "Reference Value", V1) of each device is within the range 208 - 216 counts, and
within 5 counts of each other.
If the Reference Value is substantially reducing between the beginning and the end of the Z-
loop, this is an indication that the wiring is out of specification, resulting in signal loss. This
could be caused by wiring that is inadequately sized, a loop that is too long, by loose
connections, or similar faults. If this is the case, the fault must be found and rectified.
Data wiring RS485
Check that RS485 data cabling connecting panels together meets the requirements of the
Ziton ZP Wiring Guide. As a guideline, this must be high-quality, screened, data cable, with
a maximum of 2000 metres of cable connected in any one network.
The cable terminating jumpers on the communications boards must be set correctly; see the
applicable equipment data sheets.
