LEA FINALS Flashcards
measures adopted to prevent unauthorized access to equipment, facilities, material and document and to safeguard them against espionage, sabotage, damage, loss and theft.
PHYSICAL SECURITY
Any structure or physical device capable of restricting, deterring, delaying illegal access to an installation.
BARRIER
an unobstructed area maintained on both sides of the perimeter barrier
Clear zone –
An additional overhang or barbed wire placed on vertical perimeter fences facing upward and outward with a 45-degree angle with three to four strands of barbed wires spaced 6-inches apart.
TOP GUARD
Normally provided at main perimeter and entrance to secure areas located out of doors, and manned by guards on a full-time basis.
GUARD CONTROL STATION
House-like structures above the perimeter barriers.
It gives a psychological effect to violators.
GUARD TOWER
It provides a means of continuing illumination during hours of darkness.
PROTECTIVE LIGHTNING
It is otherwise called as stationary luminary.
CONTINIOUS LIGHTING
The intensity is focused to the intruder while the observer or guard remains in the comparative darkness
GLARE PROTECTION TYPE
It is generally employed where, due to surrounding property owners, nearby highways or other limitations, it is necessary for the light to be more precisely focused.
CONTROLLED LIGHTNING
It is designed for or to supplement continuous systems.
It can be most useful to selectively light a particular area in an occasional basis.
STANDBY LIGHTNING
This system is manually operated and is usually made up of movable search or floodlights that can be located in selected or special locations which will require lighting only for short period of time.
MOVABLE OR PORTABLE LIGHTNING
This system is used in times of power failure or other emergencies when other systems are inoperative.
EMERGENCY LIGHTING
It is the least expensive in terms of energy consumed and has the advantage of providing instant illumination when the switch is on
INCANDESCENT LAMP
t is considered more efficient than the incandescent and used widespread in exterior lighting.
MERCURY VAPOR LAMP
It emits purplish-white color caused by an electric current passing through a tube of conducting and luminous gas.
MERCURY VAPOR LAMP
It has similar physical appearance to mercury vapor but provides a light source of higher luminous efficiency and better color rendition.
METAL HALIDE
This provides good colors rendition, high lamp efficiency as well as long life.
FLOURESCENT
These can be used to accommodate most outdoor security lighting needs, including the illumination of boundaries, fences and buildings and for the emphasis of vital areas or particular buildings.
FLOODLIGHTS
These lighting equipment received the most widespread notoriety for its value in reducing crime.
STREET LIGHTING
These are highly focused incandescent lamp and are designed to pinpoint potential trouble spots.
SEARCH LIGHTS
It assists the security in detecting, impeding, or deterring potential security threat in the installation.
PROTECTIVE ALARM
Its function is to alert the security personnel for any attempt of intrusion into a protected area, building or compound.
PROTECTIVE ALARM
– it emits aural or visual signals or both.
Sensor or trigger device
a circuit which transmit the message to the signaling apparatus.
Transmission line –
it is the signaling system that activates the alarm.
Annunciator –
It can be located in an agency and the installation is one of the subscribers.
When alarm is sounded, central station notifies police and other agency.
CENTRALIZATION SYSTEM
In this case, the sensor activates the circuit, which in turn activates a horn or siren or even flashing light located in the immediate vicinity of the alarmed area.
LOCAL ALARM SYSTEM
In this system installation circuits are led into local police or fire department by lease telephone line
AUXILIARY ALARM SYSTEM
This is a local alarm system in which a bell or siren is sounded with no predictable response.
LOCAL ALARM BY CHANCE SYSTEM
These systems are used in residence or small retail establishments, which cannot afford a respond system.
The hope is that a neighbor or passing will reach to the alarm and call for police assistance, but such a call is purely a matter of chance.
L
LOCAL ALARM BY CHANCE SYSTEM
This system is set to dial a predestined number when the alarm is activated.
DIAL ALARM SYSTEM
The number selected might be the police or the subscriber’s home number, or both.
When the phone is answered, a recording states that an intrusion is in progress at the location so alarmed.
DIAL ALARM SYSTEM
Supersensitive microphone speaker sensor is installed in walls; ceiling and floors of the protected area of any sound caused by attempted forced entry inspected by the sensor.
AUDIO DETECTION DEVICE
sensor is attached to walls, ceiling or floors of the protected areas. The sensor detects any vibration caused by attempted forced entry,
VIBRATION DETECTION DEVICE
In building or compound, all point of entry can be wired by using electrically charge strips of tinfoil wire.
Any actions that will move the foil or wire break the circuit and activate an alarm.
Metallic foil or wire is used in window or glass surfaces.
METALLIC FOIL OR WIRE
A laser emitter floods a wall or fencing with a beam so that when this beam is disturbed by a physical object, an alarm is activated.
LASER BEAM ALARM
One of the most widely used physical security devices in the asset protection program of an installation.
LOCKS
A mechanical, electrical, hydraulic or electronic device to prevent entry into a building, room, container or hiding place and to prevent the removal of items without the consent of the owner.
LOCKS
A portable and detachable lock having a sliding hasp which passes through a staple ring or the like and is then made fast or secured.
PADLOCK
Instrument for locking and unlocking.
A metal bar with notches or grooves that, when inserted into a lock and turned, operates the lock’s mechanism.
KEY
An English term used to describe a lock picker.
PETERMAN
Offer very little security.
This type of lock must therefore be used only to have privacy but not to provide a high degree of security.
WARDED LOCK
These are difficult to defeat, since they cannot be picked because few experts can manipulate the device to discover the combination.
Most of these locks have three dials, which must be aligned in the proper order before the lock will open.
COMBINATION LOCK
These are combination-type locks and that no key is used.
Pressing the series of numbered button in the proper sequence opens them.
CODE OPERATED LOCKS
These are electronically or more usually magnetic. Coded card notched, embossed or containing an embedded patter of copper locks are used to operate such locks. These are frequently fitted with recording device, which registers time of use and the identity of the user.
CARD OPERATED LOCKS
is the key element in a y security system. Without it, all other perspective devices – mechanical, electrical or electronic – would be useless
