 4.12.1 Overhead Canopy
Providing an overhead canopy at the access control area can improve lighting, protect the
guards and drivers from inclement weather, and serve as a platform for traffic control
devices, signage, and security equipment. An overhead canopy will be provided for all posts
routinely occupied by security personnel and the inspection/truck lanes unless directed by the
installation not to provide the canopy over a portion or all of the posts. The canopy should
extend over the entire access control area, providing protection for all potential guard
positions. Variable message signs (VMS) should be provided on the canopy to indicate
current force protection condition, provide driver instructions, and other general information
(2). Each lane should have lane control signals in both directions, similar to toll collection or
parking facilities, to inform incoming vehicles of the current lane configuration.
The overhead canopy also serves as a platform for lighting and security equipment. The
canopy should be designed to support the future installation of closed circuit television (CCTV)
cameras over each lane for inspection purposes or general observation.
The minimum clear height shall be 5.2m (17 ft.) to support common vehicle heights and
facilitate use of the overhead canopy for lighting or security equipment. This clear height
shall be measured from the pavement to the lowest point on the overhead canopy including
light fixtures and other equipment. The architectural appearance of the canopy shall match
surrounding features and meet the requirements of the installation exterior architectural plan.
4.12.2 Gatehouse
The gatehouse serves as the central control center for the ECF and provides shelter for security
personnel. Every ECF must have a gatehouse, designed to support three to five security
personnel (7). As the control center, the gatehouse controls the vehicle barricades, traffic
control devices, access controls, and lighting. The design of the gatehouse should be based on
consideration of the following equipment and functions:
Communications equipment
Electronic control panels for all current or anticipated future automated gates or
barriers
Monitor stations for CCTV or computer monitors associated with automation controls
An electrical room for the main electric panelboards
Locker storage for traffic control devices, weapons, and personnel equipment including
vehicle inspection kits and the pre-positioning of personal protective equipment for
CBR exposure
Computer servers for future automated identification systems
Counter or work space
A unisex restroom.
4.12.3 Sentry Booth
The sentry booth is located in a median strip between incoming and outgoing lanes. The
sentry booth provides one or two guards with protection against the weather and potential
threats (1). The sentry booth should have space allotted for electronic control panels for gate
automation equipment, workspace incorporating space for computer monitors, and an
electrical panelboard. It should be possible to enter or exit the sentry booth from either side
of the structure.
