Basically, the Fire Alarm system is used to prevent our life and properties. Fire alarm gives alarm to human to be protected from fire. It performs the given functions below:
- Trigger the presence of fire.
- Notify Inhabitants.
- Let-in – know the fire Department.
- As well as operate other fire safety too.
This system works fast and prevents a lot of lives in the surrounding. This system detects once the feel of smoke in the surrounding area. There are various types of Fire Alarms in Pakistan. The most common and highlighted are
- Addressable Fire Alarm System
- Conventional Fire Alarm system
Addressable Fire Alarm system
Addressable Fire Alarm system just works like a computer, it detects the whole defect at once. It works by having every detection and notification connected to each other and to the addressable alarm panel. The addressable fire alarm system transfers crucial information to the control panel with a wider range of data. This system can identify the exact location of smoke and fire.
This system is consists of numerous devices, all are appropriately classified and connected. For the detection of inputs and outputs, there is special security. More ever the most amazing system is to acknowledge systems in various alert systems.
Input addressable fire alarm system
- Heat Detector
- Smoke detector
- Manual Pull station
- Sprinkler System inputs
- Standard pressure and flow control switches
Output Addressable Fire Alarm System
- Audible Warning relays
- Door control relay
- Auxiliary Function Control.
Benefits of Addressable Fire Alarm:
This fire alarm will help to detect the location and help responders to know where to go exactly and provide quick information of the exact area. The additional benefit is to improve reliability and reduce false alarms. The main benefit of this alarm system is that it diagnoses its parts with self-monitoring abilities for quick repair and protection.
Testing and Monitoring of Alarm System
Addressable fire alarm systems require routine monitoring of the health of each device that is connected. Alarms will transmit a signal to indicate weakness or malfunction of each connected device. As each component carries an address which makes the problem source easily identifiable and it can be serviced easily. As it has the ability to self-diagnose so repair ensures whenever needed the system will function properly. Fire alarms contain independently wired alarms, which require each device to be checked separately to ensure functionality, otherwise, it can result in disaster.
Conventional Fire Alarm System:
The conventional fire alarm is a workable fire protection solution. Conventional fire alarms were the first fire alarm that comes to market. These alarm systems have zones on them, which are basically just circuits. This fire alarm detector has its own unique address. These fire alarms are ideal for small buildings like schools, stores, restaurants, and apartments. They go off individually when they detect smoke or heat and will help everyone escape from the building safely.
ADVANTAGES OF CONVENTIONAL FIRE ALARM SYSTEMS:
Conventional fire alarm systems are easy to set up in a zone because each zone has hardwired to a control panel. These alarm systems are not too much in cost and are easily affordable as well as can be fixed with less labour.
DISADVANTAGES OF CONVENTIONAL FIRE ALARM SYSTEMS:
The main disadvantage of using conventional panels is that we cannot predict within a circuit which device has been activated. The fire may be in a small place, but according to the emergency responders, a fire could exist anywhere within a zone.
- Cost is a little overpriced for larger systems.
- The Detection of smoke or a fire is according to zone, in case of emergency could delay responders from locating the fire because it could be multiple areas rather than indicating a specific location.
- Conventional alarm panels are usually called “dumb” panels because of the lack of the ability to provide detailed information, like details of event history or internet connection for notification of alarm.
