than incandescent lamps, however, they require several minutes to warm up and restart
after power is interrupted. This period of time, which could be 15 to 20 minutes, is
unsatisfactory for security operations. The 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 per
TM 5-811-1. 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.
6-14.5 General Requirements
Provide the ECF with multiple, redundant luminaires to ensure the loss of a single
luminaire does not seriously degrade the total available lighting available for security
personnel.
The lighting at the ECF should be designed as controlled lighting, to reduce light
pollution and increase traffic safety. Glare projection or glare lighting should be avoided
where a safety hazard would be created. Use luminaires that are classified as cutoff or
semi-cutoff.
Where an ECF includes modifications to the installation perimeter lighting system refer
to IESNA HB-9 and TM 5-811-1 for guidance on the design of installation perimeter
lighting.

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 to increase resistance to a moving vehicle threat. In addition, the gate must
have Type III Barricade markings in accordance with MUTCD (3 per lane) secured to
the gate horizontally. This configuration enables a reduced potential penetration,
maximizes standoff, and prevents entry of pedestrians during periods when the ECF is
not in use.
The fence gates at ACPs must maintain an equivalent level of security as the
A
adjacent fence/barriers.

PERSONNEL PROTECTION
Design the ECF to ensure safety of the security personnel operating the access control
zone. All ECF facilities, or other manned posts, should be afforded crash protection
(from traffic in either direction). Passive barriers such as bollards, reinforced concrete
walls or knee-walls, or crash cushions should be used to protect personnel standing on
the traffic islands.
