4.5 Connection Checking and Device Registration
4.5.1 Connection Checking
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 FIRE ALARM OUTPUT, SOUNDER CIRCUIT OUTPUT and F.P.E. OUTPUT should
be equal to the end-of-line resistance.
