NT Security would need a few feet of wall space in a well ventilated IT room to mount the access control main panel and sub panels. We will run wires to each other doors and depeneding on the length we offer a wireless soution as well. Once the wiring is in place we will install all the locks, card readers, and other means of egress per code. Depending on the amount of doors, size of the building, and the General Contract depends on how long the installation will take. For example a 3 door access control system can be complete in 2-5 days while a 40 door system can take 3-5 weeks. There are many moving parts including working around other trade memebers and inspections.
