## Questions & Answers

**Q: Does it interconnect with x-sense wireless model?**
A: No, the XP06 cannot be connected to X-Sense Link+ series alarms. The XP06 is an AC hardwired detector, while X-Sense Link+ series alarms like SC07-W are connected through RF (radio frequency) technology. The XP06 can be interconnected with other X-Sense hardwired alarms such as the X-Sense XP04 hardwired detectors.

**Q: Is this hardwired or battery power only?**
A: The XP04 is an AC-powered combination smoke and carbon monoxide detector and contains a replaceable 9 V alkaline battery backup. Note that the battery backup is only used in the event of a power failure and is slowly consumed, so you do not have to worry about frequent battery replacement.

**Q: Is the green light on all the time?**
A: No. The LED indicator flashes green once every 60 seconds in standby mode, indicating normal operation.

**Q: How much of the house does it cover**
A: The single room coverage is 215-430 sq ft. If your room is larger, you should install several devices.
