=============================
Fire Alarm Systems are designed to alert us to an emergency so that we can take action to protect ourselves, staff and the general public.
Whatever the method of detection is, if the alarm is triggered, sounders will operate to warn people in the building that there may be a fire and to evacuate.
In this video, we will have a look at the structure and types of the “Fire Alarm Systems”.
The “Brain” of the system is the Fire Alarm Control Panel. It is the central hub for all of the detector signals to be wired to and provides a status indication to the users.
The unit can also be set up to simulate an alarm for use in routine Fire and evacuation drills, so all staff knows what action to take in the event of a real fire.
There are a wide array of different types, but we can divide them into groups including Heat detectors, Smoke detectors, Carbon Monoxide detectors, Multi-sensor detectors, and Manual Call Points.
A Heat detector can either work on a fixed temperature basis, where it will trigger an alarm if the temperature exceeds a pre-set value or they can work on the rate of change in temperature.
There are three basic types of smoke detectors including Ionization, Light Obscuring, and Light Scattering.
In the Light obscuring smoke detector, smoke interferes with a light beam between a light source and photocell. The photocell measures the amount of light it receives.
The variation in photocell output is being used to initiate an alarm. This type of detection can be used to protect large areas with the light source and photocell positioned some distance apart.
The light scattering smoke detector operates on the Tyndall effect; a photocell and light source are separated from each other by a darkened chamber such that the light source does not fall on the photocell.
The photocell output is being used to initiate an alarm.
Carbon monoxide detectors are known also as CO fire detectors and are electronic detectors used to indicate the outbreak of fire by sensing the level of carbon monoxide in the air.
Carbon Monoxide fire detectors use the same type of sensor as those in the home but are more sensitive and respond more quickly.
Carbon monoxide detectors have an electrochemical cell, which senses carbon monoxide, but not smoke or any other combustion products.
The Multi-sensor detectors combine inputs from both optical and heat sensors and process them using a sophisticated algorithm built into the detector circuitry.
When polled by the control panel the detector returns a value based on the combined responses from both the optical and heat sensors. They are designed to be sensitive to a wide range of fires.
A Manual Call Point or Break Glass Call Point is a device which enables personnel to raise the alarm by breaking the frangible element on the fascia; this then triggers the alarm.
Fire Alarm Systems can be broken down into four main types; “Conventional”, “Addressable”, “Intelligent Fire Systems” and “Wireless Systems”.
In a Conventional Fire Alarm System, physical cabling is used to interconnect several call points and detectors, the signals from which are wired back to the main control unit.
The detection principle of an Addressable System is the same as a Conventional System except that each detector is given a set Address (usually by means of a dip-switch) and the Control Panel can then determine exactly which detector or call point has initiated the alarm.
In our next type of System, which is an Intelligent Fire Alarm system, each detector effectively incorporates its own computer which evaluates the environment around it and communicates to the Control Panel whether there is a fire, fault or the detector head needs cleaning.
The final type of system we will consider is the Wireless Fire Alarm System. These are an effective alternative to traditional wired fire alarm systems for all applications.

I have been a fire engineer for 9 years now so I can say yes this video is good I loved how you guys broke down how detectors work and call points too if most of my clients would see this too might stop some call outs too.

It helps the residents to understand why it is important to install fire alarm system, and why we need to maintain the devices regularly. And as the wireless technology upgrading, which can help us to upgrade the existing building fire alarm system, no more cable work, and complex commissioning, and realize the IoT Function to monitor the system anytime.

@tarinaten2053

Good presentation, but a little dumbed-down, maybe. I don't know where RealPars got a limit of 99 devices on addressable loop. He might have been talking about a specific brand control panel. I'm most familiar with Honeywell (formerly Ademco) Panels. The Honeywell Vista-128FBP Panel (FBP=Fire Burglary Panel) supports up to 120 addressable devices on its multiplex loop, in addition to 8 on-board hardwired loops that don't use addressable devices. The Honeywell/Ademco Vista-250FBP Panel supports up to 242 addresses on its multiplex loop, in addition to its 8 on-board supervised zones that support non-addressable fire/smoke detection devices. Also, OP made it sound like his four kinds of systems were separate and exclusive of each other. All the major Fire Alarm Panel brands in North America are "hybrid" systems and support conventional on-board (wired at control panel) supervised loops + multiplex loops with addressable sensors + "intelligent sensors" + wireless sensors; all in the same system; if Fire Code permits. In the USA, Fire Code requirements for system equipment varies in different locations, though some basic requirements are universal. Another minor fact not mentioned is that the Control Panel and Keypad(s) are separate devices. When we in the industry refer to a "Control Panel", we are talking about the "brains" of the system, the PCB (Printed Circuit Board) that receives and processes the sensor signals, determines what action to initiate, and informs the User of status, via the Keypad display. The KEYPAD is often conflated/confused with the Control Panel, Possibly because it's often mounted on the front of the Panel cabinet, but the Keypad(s) is/are simply the interface between the Control Panel and the User. a User may have several Keypads, but there is only one Control Panel.

usually every line in fire alarm system can get more elements for example 256, in my country, in Poland, it is law obligation that max element number in one line is 127 as you said

Very interesting to hear what the standards are in other countries. Here in New Zealand our national fire protection standards book states no more that 99 devices per loop on an analogue addressable system
In terms of accuracy, This is fairly accurate, except those initiating devices are European call points. The USA & Canada use Pull Stations. Same with those Notification Appliances, Those look like European Sounder-Strobes, While the USA & Canada use Horn-Strobes, Chime-Strobe’s, Or Speaker-Strobes, or the remote variants of strobes, speakers, horns, or chimes.

Been working on Fire alarms since 1998, straight out of the Submarine service. They're super boring to me now. I got a job with the school district so I could fix more than life safety systems. Intercoms, Auditium lighting, sound, PA, scoreboards etc. Fire alarm service/Programming is what landed me the job though. Good techs are hard to find.
