3.4 Control circuit terminals
(1) Terminal layout
(2) Instructions for wiring of the control circuit terminal
1)
Terminals 5, SD and SE are common to the I/O signals and isolated from each other. Do not earth (ground).
Avoid connecting the terminal SD and 5 and the terminal SE and 5.
2)
Use shielded or twisted cables for connection to the control circuit terminals and run them away from the main and
power circuits.
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
2
gauge for connection to the control circuit terminals.
If the cable gauge used is 1.25mm
2
or more, the front cover may be lifted when there are many cables running or
the cables are run improperly, resulting in an operation panel contact fault.
7)
The wiring length should be 30m (98.43feet) maximum.
Terminal screw size: M3.5
Tightening torque: 1.2N·m
