If this is a new site, you may not have staff settled for this location as of yet, but we do recommend that prior to opening, you should in the least have maybe the construction team on the call list - if installation timing allows.
You can also opt to keep the alarm “Out of Service” until you are ready to open and have your staff in place. You can use the link as often as you need to update your call list, so it is no problem to put a list into the system for the construction team and then submit a new list once you have staff and are opening if that is what you want.
(Be advised, billing for the monitoring account begins upon completion of the installation – if you opt to leave the system “Out of Service” until opening, the Central Station will not respond to any alarm events, but the account will still be active.
