4.5 Connection Inspection and Device Registration
4.5.1 Connection Inspection
Check the circuit connected with the FACP. Measure the insulation resistance between
loops and between loops and ground, which should be more than 20MΩ. Measure the
load of detection loops, which should be more than 1kΩ. The resistance between cables
of ALARM ROUTING, OUTPUT TO SOUNDER and OUTPUT TO FPE should be equal
to the end-of-line resistance.
4.5.2 Device Registration
Step 1: Set the FACP into commission state. Press SYSTEM SETUP and enter system
setup menu. Choose
“3 WORKING STATE SETUP”, you can then set the FACP as
commission or monitoring state (Fig. 4-9).
