Mains Powered Smoke Alarms
A mains powered smoke alarm is a fire protection device that does automatic sensing of the presence of smoke as the main indicator of fire. It goes off to give a warning to the occupants of the building. This type of alarm is often connected to the house electrical circuit as the main source of its operational power. EI 140 Series Standard smoke alarms provided by our company are effective and contemptible. Get EI 140 Series Standard at low-priced. The Nest smoke alarms can be installed without the need for Wi-Fi, but these can be more expensive compared to the regular smoke alarm that requires Wi-Fi for a connection. Mains powered smoke alarms are fitted with several features to enable proper functioning. These features include the following;
The voice and smoke alerts help in the identification of the type of danger and the exact location where the source of fire is identified. For instance, if the smoke is first detected in the bedroom, the voice and location alert will give that notification. Additionally, the alarm makes sounds on top of the voice alerts. It allows occupants of the building to take the most appropriate measures. Its primary purpose is to detect smoke and immediately alarm people to awake of the impending danger.
The modern system is different from the ancient one which required one to do a hardwiring to the electrical systems. Modern technology allows for interconnecting of the alarm system with the use of wireless mains alarm systems. If the alarm goes off in one room, it alerts occupants in different parts of the house, allowing them to find an escape route out. Some of the mains smoke detectors have battery backup systems. These backup systems allow continuous sounding of the alarm in case power goes off. This makes it reliable to use.
The mains smoke alarms are fitted with safety path lights to help in illuminating the escape route to safety. This makes it easy for the people to get out of the house without stumbling to cause accidents as they try to escape. This makes it easy to vacate the room with minimal casualties. The mains powered smoke alarms are set in such a way that they continue operating for as long as a power supply is available. With the in-built battery, they provide continuous functionality even when there is a power outage.
The modern house units are fitted with these types of alarm systems during the wiring phase. Given the fact that they involve mains electricity which may be dangerous, the installation is done by experts in electrical installation and alarm systems. Unlike battery smoke alarms, they operate continuously without a need to check and change batteries. According to various tests, mains smoke detectors are more reliable and faster in detecting problems compared to the rest. However, the main downside of using these alarms is since they need an expert to install, they will also need an expert for maintenance.

TYPES OF ALARMS
There are mainly four types of smoke alarm currently on the market – ionisation, optical (also described as photo electronic), heat and combined.
IONIZATION
These are the cheapest and cost very little to purchase. They are very sensitive to small particles of smoke produced by fast flaming fires, such as paper and wood, and will detect this type of fire before the smoke gets too thick. They are marginally less sensitive to slow burning and smouldering fires which give off larger quantities of smoke before flaming occurs. They can also be too over-sensitive near kitchens.
OPTICAL
These are more expensive but more effective at detecting larger particles of smoke produced by slow-burning fires, such as smouldering foam-filled upholstery and overheated PVC wiring. They are marginally less sensitive to fast flaming fires. Optical alarms can be installed near (not in) kitchens, as they are less likely than ionisation alarms to go off when toast is burned.
COMBINED SMOKE & CARBON MONOXIDE ALARM
Alarms that combine both smoke detection and CO alarm protection in one ceiling-mounted unit. This reduces costs and takes up less of your living space.
COMBINED OPTICAL SMOKE & HEAT ALARMS
These are more expensive but more effective at detecting larger particles of smoke produced by slow-burning fires, such as smouldering foam-filled upholstery and overheated PVC wiring. They are marginally less sensitive to fast flaming fires. Optical alarms can be installed near (not in) kitchens, as they are less likely than ionisation alarms to go off when toast is burned.
HEAT ALARMS
They detect the increase in temperature from a fire and are insensitive to smoke. They can therefore be installed in kitchens. They only cover a relatively small area of a room, so potentially several heat alarms need to be installed in a large kitchen.
