CAUTION
If you conduct an open-close check for contact output 4, Alarm 016 or Alarm 017 will occur.
This is because the built-in heater power of the detector, which is connected to contact output 4,
is turned off during the above check. So, if the above alarm occurs, reset the equipment or turn
the power off and then back on to restart (refer to Section "10.10 Reboot").
