(d)  Security.

(1)           The PSAP and other buildings that house essential operating equipment shall be protected against damage from vandalism, terrorism, and civil disturbances.

(2)           Entry to the PSAP shall be restricted to authorized persons.

(3)           Exterior entryways to the PSAP shall have a security vestibule. "Security Vestibule" means comprising a compartment with two or more doors to prevent unobstructed passage by allowing the release of only one door at a time.

(4)           Door openings shall be protected by listed, self-closing fire doors that have a fire resistance rating of not less than 1 hour.

(5)           Where a PSAP has windows, the following requirements shall apply:

(A)          Windows shall be a minimum of 4 ft (1.2 m) above floor level.

(B)          Windows shall be rated for bullet resistance to Level 4 as defined in UL 752, Standard for Safety Bullet-Resistant Equipment, which is hereby incorporated by reference, including subsequent amendments and editions.  This may be accessed at no cost at http://ulstandards.ul.com/standard/?id=752.

(C)          Windows that are not bullet resistant shall be permitted provided that they face an area that cannot be accessed or viewed by the general public.

(D)          Windows that are required to be bullet resistant shall be configured so that they cannot be opened.

(E)           Walls with bullet-resistant windows shall be required to provide the same level of protection as the window.

(6)           Means shall be provided to prevent unauthorized vehicles from approaching the building housing the PSAP to a distance of no less than 82 ft (25 m).  Alternatively, unauthorized vehicles shall be permitted to approach closer than 82 ft (25 m) if the building has been designed to be blast resistant.

(e)  Lighting.

(1)           Artificial lighting shall be provided to enable personnel to perform their assigned duties.

(2)           The PSAP shall be equipped with emergency lighting that shall illuminate automatically immediately upon failure of normal lighting power.

(3)           Illumination levels shall be sufficient to allow all essential operations.

(f)  Circuit Construction and Arrangement.

(1)           As-built drawings shall be provided.

(2)           Circuits shall not pass over, under, through, or be attached to buildings or property that are not owned by, or under the control of, the PSAP or the entity that is responsible for maintaining the system.

(3)           911 call instruments installed in buildings not under control of the PSAP shall be on separate dedicated circuits.

(4)           The combination of public emergency services communication and signaling (C&S) circuits in the same cable with other circuits shall comply with the following:

(A)          Other municipally controlled C&S circuits shall be permitted; or

(B)          Circuits of private signaling organizations shall be permitted only by permission of the PSAP.

(g)  Underground Cables.

(1)           Underground communication and signal cables shall be brought above ground only at points where the PSAP has determined there is no potential for mechanical damage or damage from fires in adjacent buildings.

(2)           All cables that are installed in manholes, vaults, and other enclosures intended for personnel entry shall be racked and marked for identification.

(3)           Cable splices, taps, and terminal connections shall be located only where accessible for maintenance and inspection and where no potential for damage to the cable due to falling structures or building operations exists.

(4)           Cable splices, taps, and terminal connections shall be made to provide and maintain levels of conductivity, insulation, and protection that are at least equivalent to those afforded by the cables that are joined.

(h)  Aerial Cables and Wires. Protection shall be provided where cables and wires pass through trees, under bridges, and over railroads, and at other locations where damage or deterioration is possible.

(i)  Wiring Inside Buildings.

(1)           Wiring at the PSAP shall extend to the operations room in conduits, ducts, shafts, raceways, or overhead racks and troughs of a construction type that protects against fire and mechanical damage.

(2)           Cables or wiring exposed to fire hazards shall be protected from the hazards.

(3)           At the PSAP, cable terminals and cross connecting facilities shall be located either in or adjacent to the operations room.  

(4)           All wired dispatch circuit devices and instruments whose failure can adversely affect the operation of the system shall be mounted in accordance with the following:
