connection. The maximum current of the circuit depends on the number of fire
supervisory device. Do not overload.
Connection of Class A Loop
A Class A loop is shown in Fig. 4-7.

Note: If more than 32 devices are connected to the loop, loop isolators shall be
used and each loop isolator shall not cover more than 32 detectors.

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 20M
Ω
. Measure the
load of detection loops, which should be more than 1k
Ω
. 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.
