Note: If more than one device has the same address the LCD display will show a
report of the device numbers affected. The engineer may also notice a device
missing from the expected total quantity of loop devices.
6, Interrogate the devices on an individual basis as described in section 23.29 on
page 75. To view correct electronic operation, press button 2 to set command bit 1
(self test mode). Press again to return detector to quiescent state. To turn a device
LED on (to identify its correct location), press button 3 to set command bit 2.
Press again to return the detector to quiescent state. To turn a remote device LED
on (to identify its correct location), press button 1 to set command bit 0. Press
again to return detector to quiescent state.
7. Repeat sections 1 to 6 for each loop.
WARNING: Before connecting the return leg of the loop, ensure that the returning
polarity is correct.
8. Sensor installation is now complete. Switch off the control panel.
9. Connect the return leg of loop 1 to the I1+ and I1- terminals. Repeat for all
remaining loops.
10. Switch on the control panel and observe that the no fault conditions are indicated.
If there are any loop faults caused by open circuit conditions or operation of a loop
isolator then the panel will indicate a line fault for the corresponding loop.
9.5.3Commissioning a Network System
1. Ensure the network card is fitted in each panel and that the network cabling is
correctly installed.
2. Ensure that each panel has been commissioned as a stand-alone panel as detailed
above.
3. Enable the network card on each panel. The panels will automatically recognise
the other panels on the network - a manual configuration process is not required.
4. Generate a fire condition on each panel in turn and observe that the event is
displayed correctly at each other panel. The response of each panel depends on its
response configuration.
5. Repeat step 4 for alert, fault and indication only conditions.
6. Test each panel on the network as follows:
i) Operate evacuate on the next network panel.
ii) Observe that the event is displayed at the panel under test.
iii) Operate silence alarms and reset at the panel under test and observe that the
system responds as expected.
iv) Repeat i, ii and iii for all other nodes except the panel under test
7. Identify each item of network cause/effect cause. i.e. cause and effect where the
panel response is on a different node to the event which causes that action.
8. Action each event in turn and observe that the network cause and effect operates
correctly.
Note: It is not necessary to re-test each item of local cause/effect, i.e. cause/effect
where the event and response are on the same panel. this is tested as part of the
stand-alone panel commissioning.
