Types of Protective Alarm

FIRE ALARM, BANK ALARM

Any visual or audible signal produced by a device or system to warn the occupants of the building or fire fighting elements of the presence or danger of fire to enable them to undertake immediate action to save life and property and to suppress the fire.

FIRE ALARM

a device placed at the ceilings of the floor that detects smoke, typically as an indicator of fire

SMOKE DETECTOR

a hollow device made of metal that makes a ringing sound

FIRE BELL

a type of built in sprinklers which works by the increase of room temperature and which automatically operates the system to put out the fire.

AUTOMATIC SPRINKLER

G.I. (galvanized iron) steel or plastic pipes located inside the building from the lowest to the top floor with water under pressure for use in case of fire.

STANDPIPES

It is a mechanical device strategically located in an installation or in a street where a fire hose will be connected so that the water will be available to extinguish a fire

FIRE HYDRANT

is a fire fighting equipment which can be a fire fighting equipment which can be portable or in a cart that is used to put out fire depending on the contents to extinguish certain types of fire.

FIRE EXTINGUISHER

Classes of fires

CLASS A TO E

involving ordinary combustible materials such as wood, cloth, and paper, requires an extinguishing agent which cools

CLASS A

fires involving flammable and combustible liquids, such as solvents, greases, gasoline, and lubricating oil, require an extinguisher which removes oxygen or cuts the chain reaction

CLASS B

fires involve energized electrical equipment

CLASS C

metal fires such as magnesium

CLASS D

fires involving flammable gasses

CLASS E

What are the fire alarm devices

SMOKE DETECTOR, FIRE BELL, AUTOMATIC SPRINKLER, STANDPIPES, FIRE HYDRANT, FIRE EXTINGUISHER

What are the bank alarms

FOOT RAIL ACTIVATOR, KNEE OR THIGH BUTTON, FOOT BUTTON, DOUBLE SQUEEZE BUTTON

They are placed on the floor in such a position that tellers may activate the alarm by placing the front of their foot to foot rail to activate the alarm

FOOT RAIL ACTIVATOR

It is installed inside the teller station so that they can be activated by knee or thigh pressure

KNEE OR THIGH BUTTON

Like the foot rail, it permits alarm activation in relatively safety, while both hands remain clear in view of the robbers

FOOT BUTTON

It requires pressure on both sides of the device , thus the probability of accidental alarm is reduced.

DOUBLE SQUEEZE BUTTON

What are the other types of alarm system

METALLIC FOIL OR WIRE, PHOTOELECTRIC OR ELECTRIC EYE DEVICE, AUDIO DETECTION DEVICE, VIBRATION DETECTION DEVICE

What is the minimum required clear zone distance between the perimeter barrier and exterior structures outside the protected area?

20 FEET

Within the protected area, what is the minimum required clear zone distance between the perimeter barrier and any structure?

50 FEET

What color of light that does not attract the insects

AMBER

It will detect any action that moves or break the foil or wire

METALLIC FOIL OR WIRE

A light beam is transmitted at a frequency of several thousand vibrations per second. It is connected by a wire to control station and when an intruder crosses the beam , he breaks the contact with the photoelectric coil which activates the alarm

PHOTOELECTRIC OR ELECTRIC EYE DEVICE

It is a supersensitive microphone speaker sensor that is installed in the walls, ceilings, and floors of the protected area

AUDIO DETECTION DEVICE

devices mounted on barriers and are used primarily to detect an attack on the structure itself. When movement or vibration occurs, the unstable portion of the circuit moves and breaks the current flow, which produces an alarm

VIBRATION DETECTION DEVICE

Other Alarm Devices:

MAGNETIC DOOR CONTACT, PASSIVE INFRARED DETECTOR OR MOTION SENSOR, PANIC BUTTON, CCTV

Often located under the counter, the button can be pressed in times of distress

PANIC BUTTON

a protective device usually placed in the door, and window that can send notification when the opening and closure occurs;

MAGNETIC DOOR CONTACT

are able to distinguish if an infrared emitting object is present by first learning the ambient temperature of the monitored space and then detecting a change in the temperature caused by the presence of an object

PASSIVE INFRARED DETECTOR OR MOTION SENSOR

a system consisting of a television camera, video monitor, and a transmission medium (Cable, fiber or wireless) connecting the two. It is used to monitor the premises

CLOSE CIRCUIT TELEVISION SYSTEM OR CCTV

is an aural or visual signal given by the annunciator to the security when intruders actuate certain devices in a protected area

PROTECTIVE ALARM

3 Basic Parts of Alarm System

SENSOR OR TRIGGER DEVICE, CIRCUIT OR TRANSMISSION LINE, ANNUNCIATOR/ENUNCIATOR

device that can sense an abnormal condition within the system and provide a signal indicating the presence or nature of the abnormality

SENSORS OR TRIGGER DEVICE

It is the communication channel that conveys the information from all sensors in the system to the signal by means of wire, radio waves

CIRCUIT OR TRANSMISSION LINE

is a visual or audible signaling device. The actual alarm may be audible or silent, a bell, buzzer, phone ringing, or flashing of light.

ANNUNCIATOR OR ENUNCIATOR
