5-1. Preparing for Start-up

Before supplying power, read and understand the following precautions. Ignoring these precautions may
cause an electric shock or detector damage.
• Connect the detector to a grounding circuit.
• Check that external device wiring is correct and secure.
• Check that the power supply voltage is compliant with the specifications.
• Because the external contact may be activated during startup, make sure an activated contact won't
affect an external device.

Detection mode is used for normal operations. (Detection Mode is activated after the power is turned on.)
The detector is restarted
after recovering from
fault.
WARNING
When the detector enters other mode from Detection Mode while an alarm is activated, the alarm is
reset.
