installation should designate the maximum acceptable period for which loss of illumination can
be tolerated, however, without specific data two (2) minutes is considered the maximum
outage period acceptable (5, 11-1). The selection of light sources, especially in the access
control zone, should include an evaluation of restart or restrike time. It may be necessary to
provide lamps and auxiliary equipment for rapid startup and restrike to provide minimal
adequate lighting in the event of a power interruption.
Where an ECF includes modifications to the installation perimeter lighting system refer to
references 5 and 6 for guidance on the design of installation perimeter lighting.
4.8 Communications and Information Technology
The guard facilities will have telephone communication capability. In addition, some
installations may require an emergency ring down telephone, which provides a direct, hard-
line connection to the installation emergency dispatch or control center. The requirements for
radio-based communication should be coordinated with the installation. Due to the potential
of computerized identification systems, the ECF shall be capable of connecting to installation
wide information technology systems. Each guard shelter will have provisions for connection to
the installation wide computer network, as well to a central server to be located in the
gatehouse. If no installation wide data cabling system exists, this capability can be achieved
through the use of the telephone system.
The ECF shall be provided with a central duress alarm, which will signal the installation
emergency control center, dispatch center, or similar designated location. The duress alarm
will be activated automatically upon emergency activation of the active vehicle barrier
As discussed in Section 4.6, to facilitate the installation of the electronic systems, spare duct
bank and conduit shall be run in a similar manner to that shown in Figure 4.5. At a minimum
provide a system of underground concrete-encased PVC ductbank and fiberglass/composite
handholes for distribution of power, control, and communications/data wiring from the ECP
control center (gatehouse) to each remote device. If no detailed locations are pre-determined
for remote devices, provide two handholes located at either end of each channelization island
and the median. The layout should consider the first automation device to be positioned prior
to the rejection point located before the main identification checkpoint. Consider the
possibility of access control systems being used for recording outbound lane activity in
addition to inbound traffic identification.
Water service for general use and for the unisex restroom in the gatehouse will be provided.
Waste system utilities will be provided for the unisex restroom. If it is technically impossible or
economically infeasible to provide these utilities to an ECF due to site constraints, the
installation may wave the requirement to provide the water and waste utilities. See Section
4.6 for electrical power requirements.
4.10 Perimeter Fence and Gate
The ECF typically begins at the installation perimeter. In most cases the perimeter is defined
and secured with a fence. Each ECF should have a gate enabling the ECF to be closed at the
installation perimeter when not in use. This gate should be reinforced with cables as indicated
