27Bypass a Sensor1

The vast majority of home security users are bound to come across a scenario where they will want to bypass one (or more) of their sensors. To clarify, when we use the term bypass, we are referencing how to set up your security system so that you can open a door or window when your system is armed without the fear of sounding the alarm. We will walk you through how to bypass one (or more) sensors for home security systems anchored down with the following three panels: Simon XTi, Simon XTi-5, and IQ Panel 2.
