Motion Detector Behavior while Exit/Entry Delay is in Progress
Hi, I have a question on Motion Detector and alarm system behavior while Exit/Entry delay is in progress. 1. As I understand, a motion detector alert is ignored by the system after it is armed AND exit delay is in progress - the assumption being that the people exiting may be causing the alert. After the motion detector's dwell time AND the exit delay completes (whichever is longer - since the exit delay may be 60 seconds and the Gen 1 motion detector dwell time is 180 seconds), the next motion detector alert is recognized by the system. This is the case regardless of whether the motion detector's placement is Entryway or Room. Is this correct? 2. Using the above example, if the exit delay is 60s and a Gen 1 motion detector is triggered on the way out, given its dwell time of 180 seconds, there are 120 seconds without the motion detector protecting - since its dwell time has to complete before it can send the next alert. Is this correct? 3. If an Entry delay is triggered, by a contact sensor - by opening a door to enter a home, and while going towards the keypad to disarm the system, a motion detector is triggered, then will the alarm sound if the motion detector's placement is Room or, because an Entry delay is already in progress, the system ignores the motion detector because an Entry delay is in progress - similar to the exit delay? OR because the motion detector's placement is Room, the alarm sounds right away, even though an entry delay is in progress, activated by a contact sensor? 4. If the system is armed and a motion detector with Entryway placement is triggered, will the system initiate an Entry delay before sounding an alarm EVEN though all the doors have contact sensors and none of the contact sensors have been activated? Thanks.

Tom, I did read the very detailed and excellent posts by @Boone. Believe it or not (unless I missed it in the extensive detail...), the questions I posted were not covered. Yes, I guess I can try and test but thought these may be design details that may already be known.

NThank you, @Boone for an incredibly detailed response! Thank you for being so generous with your time and sharing your experience and expertise. This level of detail must take a great deal of time to first discover and then of course write-up! I do have one Gen 1 Motion Detector. I will confirm that the overall behavior (with the exception of course of the dwell time) is consistent with your observations on Gen 2. Two key takeaways: 1. The 180s dwell time on the Gen 1 motion detector is unusual and potentially problematic. I presume this is hard wired into the product - not configurable/updateable by software/firmware. While possibly contrived, there could be scenarios where this duration could pose a security risk. I will revisit where I am using this and whether it should be used at all. 2. The only reason to have a motion detector in Entryway placement is if it is covering a Main Door which does not have a contact sensor. This is possible, if unlikely. Otherwise all motion detectors should use Room placement - since the Exit/Entry delays will prevent them from trigerring an alarm while leaving/entering the home. Thank you again. Your response has been tremendously helpful.

H[quote="Boone, post:4, topic:18539"] * Contact Sensor “Placement” set at: * “Main Door”: Uses delay Entry/Exit Time settings. * “Secondary Door” or “Window”: No delay. Immediate. * Motion Sensor “Placement” set at: * “Entryway”: Uses delay Entry/Exit Time settings. * “Room”: No delay. Immediate. [/quote] Thank you! No where in the manual does it explain that and I could not understand why my basement door (set as secondary door) wouldn't follow the exit delay setting. Appreciate the thorough answer.

Hi @njarwala. I would consult @Boone for this subject! Boone has an incredible write up, that can be found [HERE](https://community.ring.com/t5/Ring-Alarm/Things-you-DIDN-T-WANT-TO-KNOW-about-Motion-Detectors/m-p/49013#M4879), on Motion Detectors. I'm pretty sure this information will answer all of your questions. Also, you can always put your Ring Alarm into Self Monitoring and test your system. Just be sure to switch back into Professional Monitoring when you are done testing! :smiley:
