Thanks for the response.
Regarding the instructions, as we would be only leaving the alarm for 48 hours we should be fine without leaving any maintenance instructions. If Oakville moves towards a loner program it is more of a gap filler until they install their new alarm.
Our legal department if fine with installing a battery operated alarm as the owner will be required to install the proper alarm on the same day but prevention will return within 48 hours to confirm.
I never thought about the idea of the owner to provide a new alarm, this will be discussed with management.
You definitely bring up some interesting points.
