(5) Wiring instructions
1) Terminals 5, PC and SE are common to the I/O signals and isolated from each other. Do not ground.
2) Use shielded or twisted cables for connection to the control circuit terminals and run them away from the main
and power circuits (including the 200V relay sequence circuit).
3) Use two or more parallel micro-signal contacts or twin
contacts to prevent a contact faults when using contact inputs
since the control circuit input signals are micro-currents.
4) Do not apply a voltage to the contact input terminals (e.g. STF) of the control circuit.
5) Always apply a voltage to the alarm output terminals (A, B, C) via a relay coil, lamp, etc.
6) It is recommended to use the cables of 0.75mm
If the cable gauge used is 1.25mm
or the cables are run improperly, resulting in an operation panel contact fault.
7) The wiring length should be 30m (98.43feet) maximum.
