Currently on your system I see three sensor tamper conditions and two sensor offline malfunctions. These are not conditions you can fix remotely.
Sensor tampers on wireless sensors are due to the cover not being affixed properly/the sensor tamper switch not being closed. Remove and reattach the cover securely.
Please read the following thread for what can cause Offline conditions.
Additionally some specific sensors like 2GIG Smoke Detectors may throw offline conditions for specific circumstances unrelated to signaling, such as being beyond expiration date or having a dirty sensing element. This is usually accompanied by LED flashing and beeping from the device.
If the above link does not help resolve the offline issue, what model number are the offline smoke detectors? What is their replace-by date?
