1.2. Connecting External Sensor Input/Relay Output
• Connecting External Sensor Input (16 Channels)
☞ Connect one of two strands of signal lines for various sensors (Infrared sensor,
Heat Wire Detector, Magnetic) to a Signal ( S1 ~ S16) terminal. Connect the other
line to Ground ( GND) terminal.
(Specify sensor "NC, NO" type setting on "Sensor Setting".)
• Connecting External Sensor Relay Output (4 Channels)
☞ Factory setting for control output access point is "NC".
☞ For controlled output, access point is output if it is applied when its type is "No."
