Q

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.

A

FLOODLIGHTS

20
Q

These lighting equipment received the most widespread notoriety for its value in reducing crime.

A

STREET LIGHTING

21
Q

These are highly focused incandescent lamp and are designed to pinpoint potential trouble spots.

A

SEARCH LIGHTS

22
Q

It assists the security in detecting, impeding, or deterring potential security threat in the installation.

A

PROTECTIVE ALARM

23
Q

Its function is to alert the security personnel for any attempt of intrusion into a protected area, building or compound.

A

PROTECTIVE ALARM

24
Q

– it emits aural or visual signals or both.

A

Sensor or trigger device

25
Q

a circuit which transmit the message to the signaling apparatus.

A

Transmission line –

26
Q

it is the signaling system that activates the alarm.

A

Annunciator –

27
Q

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.

A

CENTRALIZATION SYSTEM

28
Q

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.

A

LOCAL ALARM SYSTEM

29
Q

In this system installation circuits are led into local police or fire department by lease telephone line

A

AUXILIARY ALARM SYSTEM

30
Q

This is a local alarm system in which a bell or siren is sounded with no predictable response.

A

LOCAL ALARM BY CHANCE SYSTEM

31
Q

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

A

LOCAL ALARM BY CHANCE SYSTEM

32
Q

This system is set to dial a predestined number when the alarm is activated.

A

DIAL ALARM SYSTEM

33
Q

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.

A

DIAL ALARM SYSTEM

34
Q

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.

A

AUDIO DETECTION DEVICE

35
Q

sensor is attached to walls, ceiling or floors of the protected areas. The sensor detects any vibration caused by attempted forced entry,

A

VIBRATION DETECTION DEVICE

36
Q

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.

A

METALLIC FOIL OR WIRE

37
Q

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.

A

LASER BEAM ALARM

38
Q

One of the most widely used physical security devices in the asset protection program of an installation.

A

LOCKS

39
Q

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.

A

LOCKS

40
Q

42
Q

An English term used to describe a lock picker.

A

PETERMAN

43
Q

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.

A

Most of these locks have three dials, which must be aligned in the proper order before the lock will open.

A

COMBINATION LOCK

45
Q

These are combination-type locks and that no key is used.
Pressing the series of numbered button in the proper sequence opens them.

A

CODE OPERATED LOCKS

46
Q

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.

A

CARD OPERATED LOCKS

47
Q

is the key element in a y security system. Without it, all other perspective devices – mechanical, electrical or electronic – would be useless
