System tests
After confirming that the system has been correctly installed and programmed, perform the
following tests to confirm that the equipment is functioning correctly:
Panel check
1. Disconnect the loops from the panel.
2. Jumper the "in and out" terminals of each loop, and connect 3 sensors (or other line devices)
to each loop.
3. Address these devices at any desired addresses, do not duplicate.
4. Make sure the addresses are zoned.
5. Carry out the following checks:
Check that the first analogue value (the Reference Value, V1) of each ZP device is within
the range 208 - 216 counts in the maintenance/reports to screen/point analogues menu.
If any of the devices are out of this range, then replace the panel main board. For ZX, ZR
or EX devices, check for the appropriate levels as shown in Table 26 below.
Place one device on each loop into alarm (activate callpoints, or place smoke or test-
smoke into a sensor). Make sure the panel reports an alarm and that the zone is reported
on the LCD display (correct illuminated zone and status LED).
Create a fault on one device on each loop (disconnect a callpoint, or unplug a sensor
base). Make sure the panel reports a fault and that the zone is reported on the LCD
display (correct illuminated status LED).

Z-loop wiring check
1. Disconnect the loops from the panel.
2. Bridge out any line isolators (if fitted).
3. Measure the resistance of the complete loop (combined resistance of both the positive [+]
and negative [-] legs), using a multimeter, as follows:
If the system is wired as a class-A return loop, measuring the resistance is a simple
matter. At the panel, measure the resistance of the positive leg from [+out] to [+in], and
record. Multiply by two to get resistance of the total cable and check that they are within
the required parameters as described under
Z-loop wiring parameters
on page 94.
If the system is wired as a class-B return loop, measure as follows. If the loop has Tee-
Offs, identify the longest leg (measured from the panel to the last device). At the last
device connect the positive leg to the negative leg. At the panel, measure the resistance
from the positive leg [+out] to the negative leg [-out], and record.
