1. The sensors on my doors read as open but my doors are closed so how do I fix that?
There are a few reasons this might occur. If the batteries have never been changed they may be too low to properly signal and the panel may not be getting close reports.
Try opening and closing a few times, does your panel indicate any change? After replacing the batteries, any change?
2. My panel is in my bedroom and I enter and exit my house through my garage 100% of the time. Should there be a sensor on this door? I ask because when I left my house on Friday (9/30), I received a notification that my front door had alarmed. Is this because I did not exit the house through the front door?
Typically you would want a sensor on every door, yes. Is there not one?
Do the doors have wireless sensors like this? Or are they perhaps using wired sensors and a Takeover Module? (If there is a Takeover module and its battery is low, all wired sensor zones connected to it would report low.)
If you provide the model number of the sensors we can more specifically address the issue.
My panel use to speak a voice command when I would open a door but now it doesn’t anymore. So what have I done wrong and what do I need to do to fix it?
Chimes can be controlled by “Security - Menu - Toolbox - master code - Chimes” You can set chimes for each sensor. One of the options is “Voice Only” which will announce the voice descriptor of the zone.
