[Ticket Question] Latching/non-Latching Base For Eco1000 Smoke Detector

[Secware]

Hi, I'm interested in buying a complete intruder alarm system based on the Honeywell Flex 20 panel. I want to include a smoke alarm, probably the Honeywell ECO1002 combined photo/thermal unit and connect it to the intruder alarm system. Should I buy a latching or a non-latching base?
I'd like to place the order today if possible,

If it's on it's pwn circuit then use the non latching base.
