connectors, terminators, interconnections, services, and adjustments
required for a complete and operable system.
D. The IDS will be designed, engineered, installed, and tested to
ensure all components are fully compatible as a system and can be
integrated with all associated security subsystems, whether the system
is a stand alone or designed as a computer network.
E. The IDS shall be able to be integrated with other security
subsystems. Integration with these security subsystems shall be
achieved by computer programming and the direct hardwiring of the
systems. Determination for methodology shall be outlined when the
system(s) is/are being designed and engineered. For installation

other security subsystems. The Contractor will ensure all connections
are per the OEM and that any and all software upgrades required to
integrate the systems are installed prior to system start-up.
F. For programming purposes, the Contractor shall refer to the
manufacturer’s requirements and Contracting Officer instructions for
correct system operations. This includes ensuring computers being
utilized for system integration meet or exceeds the minimum system
requirements outlined in the IDS software packages.
G. Lightening and power surges to the central alarm reporting and
display unit shall be protected at both ends against excessive
voltages. This requirement shall apply for circuits that are routed
both in underground conduits and overhead runs.
H. At a minimum, the Contractor shall install primary detection
devices, such as three electrode gas-type surge arresters, and
secondary protectors to reduce dangerous voltages to levels that will
cause no damage. Fuses shall not be permitted as protection devices.

of dust, dirt, grease, or oil incurred during installation in
accordance to manufacture instructions.
2. Prepare for system activation by following manufacturer’s
recommended procedures for adjustment, alignment, or synchronization.
Prepare each component in accordance with appropriate provisions of
the component’s installation, operations, and maintenance
instructions.
L. Tamper Switches
1. Install tamper switches to initiate an alarm signal when a panel,
box, or component housing door or cover is moved as little as 6.35 mm
(1/4 inch) from the normally closed position unless otherwise
specified.
2. Locate tamper switches within enclosures, cabinets, housings,
boxes, raceways, and fittings to prevent direct line of sight to any
internal components and to prevent tampering with switch or circuitry.
3. Conceal tamper switch mounting hardware so that the location of the
switch within the enclosure cannot be determined from the exterior.
M. Unique IDS Installation Components:
1. BMS Surface Mounted:
a. Surface mounted BMS housing for the switch element shall have the
capability to receive threaded conduit. Housing covers for surface
mounted BMS, if made of cast aluminum, shall be secured by stainless
steel screws. Magnet housing cover shall not be readily removable and
BMS housings shall be protected from unauthorized access by a cover
operated, corrosion-resistant tamper device.
b. Conductors running from a door to alarm circuits shall be contained
within a flexible armored cord constructed from corrosion-resistant
metal. Each end of the armored cord shall terminate in a junction box
or other enclosure. Armored cord ends shall be mechanically secured to
the junction boxes by clamps or bushings. Conductors within the
armored cord shall be provided with lug terminals at each end.
Conductors and the armored cord shall experience no mechanical strain
as the door is removed from fully open to closed position. Switch
circuits shall initiate an alarm if a short circuit is applied to the
door cord.
c. For exterior application on double gates, both BMS elements must be
mounted on the gate. Flexible armored cord constructed from
corrosion-resistant metal shall be used to provide electrical
connection.

such that when the locking mechanism is secured, the door bolt engages
an actuator, mechanically closing the switch.

section, even though spacing closer than that required for midrange
sensitivity may result.
c. House sensors in protective mountings and fasten to surface with
concealed mounting screws or an epoxy.
d. Adjust discriminator on the job to precise needs of application.

retain the center bolt (lever arm), which functions as a lever to
translate movement of the attached horizontal wire into contact
closure. When the neoprene cap is firmly seated on the cup-shaped
polycarbonate housing, it shall function as the fulcrum for the lever
(bolt).
b. Upper exposed end of the lever shall be threaded to accommodate
clamping to the horizontal wire. The lower end of the lever, which is
fashioned to serve as the movable electrical contact, shall be held
suspended in a small cup-shaped contact that floats in a plastic putty
material.
c. Plastic putty used shall retain a degree of elasticity under
varying temperature conditions and provide the sensor switch with a
self-adjusting property. This provides the switch with a built-in
compensating mechanism that ignores small, very slow changes in lever
alignment (i.e. which may result from environmental changes such as
extreme temperature variations and ground seepage due to weather
conditions) and to react to fast changes only, as caused by manual
deflection or cutting of the wires.
d. Contractor shall provide metal slider strips having slots through
which the barbed wires pass. Wires shall be prevented from leaving the
slots by rivets. A slider strip shall be used to translate normal
forces to the barbed wire and to the horizontal displacement of the
sensor.

post except where sensor posts or anchor strips are installed.
f. Separation between slider elements along the fence shall be 3000 mm
(10 feet).
g. Attach wires of sensor to existing, specially installed fence
posts, called anchor posts, located equidistant on both sides of
sensor posts and at ends of sensor zone run.
h. Anchor strip shall be a strip of steel plate on which fastening
plates are installed. Weld or otherwise attach the strip to anchor
post and ends of tensed barbed wires wrapped around the fastening
plates. Attempts to climb on fastening plates or on the attached
barbed wires shall cause plates to break off, creating an alarm and
making it impossible to defeat the system by climbing at the anchor
post.
i. The use of barbed wire as part of the IDS system shall be suitable
for installation under a preload tension of approximately 392 N 88
pounds and be flexible enough for convenient manipulation during
tensioning. Double-strand 15 1/2-gage barbed wire shall be the minimum
acceptable.
6. Electromechanical Fence Sensors:
a. The fence length shall be divided into 100m (300 ft). or zones.
b. Sensors shall consist of individual electromechanical sensing units
mounted every three-thousand and 3045mm (10 ft). on the fence fabric
or posts and wired in series to a sensor zone control unit and
associated power supply.
7. Electrostatic Field Sensors:
a. Sensors shall be capable of following irregular contours and
barrier bends without degrading sensitivity below the specified
detection level.
b. In no case shall a single sensor zone exceed 100m (300 ft). or be
long enough to significantly degrade sensitivity.
c. Adjacent zones shall provide continuous coverage to avoid a dead
zone. Adjacent zones shall be designed to prevent crosstalk
interference.
d. Exterior components shall be housed in rugged corrosion-resistant
enclosures, protected from environmental degradation and include
tamper switches.
e. Interfacing between exterior units shall be carried in underground
cables.
f. Exterior support hardware shall be stainless or galvanized to avoid
tension degradation.
g. Sensor and field wires shall be stainless steel. Wire spacing for
various configurations shall be maintained constant throughout each
zone and shall be uniform with respect to the ground and follow
manufacturer's specifications.
h. Signal processing equipment shall be separately mounted such that
no desensitized zones are created within the zone of detection.
