How we install the AC43
Door hardware, cabling, power and the fire alarm interface are all done by our own electricians, so one contractor is responsible for the door working. We set up doors, schedules and credentials in Command and train whoever manages them.
Other access control models: AC12, AC62, AX11, AD34, AD64, AF64. See all on Verkada access control or the model guide.
