Fire Angel smoke alarms have a choice 5/10 year lithium batteries depending on alarm type
Fire Angel 10 Year
Fireangel ST-622T is a ten-year-old locked battery that has a thermoptek multi-sensor. This sensor is capable of responding two times faster than an optical smoke alarm. It continually monitors temperature interchanges and an unexpected temperature rise. It has increased sensitivity. It has smart silence whereby it can silence false alarms. Also, toast proof that stops irritating alarms. Its life span is ten years and a ten-year battery locked life span. The thermoptek sensor merges the optical technology with thermal intensification to notice both slow and fast fires. Most customers rate Fire angel as being easy to install. It is cost-effective due to its long life span and its battery sealed life. It is times referred to as ‘sleepy-easy’ because it takes 8 hours for the smoke alarm to be silent ultimately. This alarm can be positioned in bedrooms, dining rooms, hallway, and living rooms. The rescue services and UK Fire mostly advocate home safety by appreciating this art and technology to develop Fire angel 10 years. It has proven to offer efficient, reliable, and preferable home safety.

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.
