The fire alarm control unit (FACU), formerly called the fire alarm control panel (FACP), contains the electronics that supervise and monitor the integrity of the wiring and components of the fire alarm system. The FACU basically serves as the brain for the alarm system (Figure 14.2).
Which fire alarm component serves as the brain of alarm systems?
FACU – Fire Alarm Control Unit
The fire alarm control unit serves as the brain of the fire alarm system by monitoring all the inputs and controlling all the outputs. Some may also refer to this as a fire alarm control panel or fire alarm panel.
What is the brain of a fire alarm system?
Fire alarm control panels are the “brain” of the fire alarm system that allow personnel to activate or deactivate the entire system at will. FACPs are manufactured in a variety of shapes, sizes, and formats depending on the manufacturer and the panel’s intended scope of use.
Which detector is used for firefighting system?
The majority of smoke detectors work either by optical detection or by ionization, and in some cases both detection methods are used to increase sensitivity to smoke. A complete fire-protection system will typically include spot smoke detectors that can signal a fire control panel to deploy a fire-suppression system.
What are the basic components of an alarm system?
The main components of a alarm system would be a sensor, a camera, a motion detector, a buzzer a flash light and batteries. It is a component that is usually used to detect noise or a movement. Sensors are usually connected to the circuit.
How does the fire alarm work?
A photoelectric smoke detector uses an infrared LED light beam to tell if there is smoke in the air. Over time, the sensor emits the light through the optical detector’s chamber. If the light detects numerous smoke particles passing through it, then an alarm is triggered.
What is a part 6 fire alarm system?
LD2 – A system incorporating detectors in all circulation spaces that form part of the escape routes from the premises, and in all rooms or areas that present a high risk of fire to occupants.
Is fire alarm same as smoke detector?
Put simply, a smoke alarm detects smoke and sounds an alarm. … Put simply, a smoke detector senses smoke only and must be connected to a fire alarm system control panel. Smoke detectors are a detection device only – not an alarm.
What are the 3 main types of fire alarm?
The three most common smoke detectors are ionisation, photoelectric, and combination ionisation/photoelectric. All smoke detectors sound an alarm, when they identify smoke, in order to notify a building’s occupants. What differentiates these detectors from one another is the way that they detect smoke.
