Using Internal Reed Switch and External Sensors
When Open/Close Sensor external sensors input is used in conjunction with its internal reed switch, Open/Close
Sensor behaves much like several sensors connected in parallel (above), meaning:
• Open/Close Sensor will be open when both internal reed switch and external reed switch sensor terminals
show open
• Open/Close Sensor will be closed when either internal reed switch or external sensor terminals show closed
Power Restore
Open/Close Sensor stores all of its settings, such as links to other INSTEON devices, with non-volatile memory.
Because settings are saved in non-volatile memory, they will not be lost when the battery is removed.

All settings and scenes will be erased and return to factory default settings.
1) If you are using Open/Close Sensor to control any responders, unlink them from Open/Close Sensor. See

3) Remove battery and wait at least 15 seconds
