by SIA Site Admin // July 11

Smoke alarms are an essential component of home safety, particularly for those living in flats, as they provide early warning in the event of a fire. There are various types of smoke alarms available on the UK market, each designed to detect specific types of fires. Knowing which alarm is best suited for your flat is crucial to ensure maximum protection for you and your neighbours.

The three main types of smoke alarms include ionisation, optical, and heat alarms. Ionisation alarms are sensitive to fast-flaming fires and are suitable for hallways or areas with combustible materials. Optical alarms, on the other hand, are more effective at detecting slow-burning, smouldering fires, such as those caused by overheating electrical wiring. They are ideal for living rooms and bedrooms. Heat alarms, which detect a rapid rise in temperature, are best suited for kitchens, as they are less prone to false alarms caused by cooking fumes.

When selecting a smoke alarm, it is important to consider additional factors such as battery life, ease of installation, and whether the alarm can be linked to other alarms within the flat or building. Some alarms also come with built-in carbon monoxide detectors, offering extra protection against this deadly gas. By choosing the right smoke alarm and maintaining it regularly, you can significantly reduce the risk of fire incidents and ensure the safety of your home and family.

Understanding Smoke Alarms

Smoke alarms play a crucial role in home safety by providing early warning in the event of a fire. There are two main types of smoke alarms commonly used in flats in the UK: Ionisation Smoke Alarms and Optical Smoke Alarms. In this section, we will discuss the features and differences between these two types of smoke detectors.

Ionisation Smoke Alarms

Ionisation smoke alarms are sensitive to small particles of smoke produced by fast-flaming fires, such as paper or wood fires. These alarms contain a small amount of radioactive material that ionises the air inside the detection chamber. When smoke enters the chamber, it disrupts the ionisation process and triggers the alarm.

Pros of Ionisation Smoke Alarms:

  • Generally quicker at detecting fast-flaming fires
  • Tend to be less expensive than optical smoke alarms

Cons of Ionisation Smoke Alarms:

  • Prone to false alarms caused by steam or cooking fumes
  • May not detect slow, smouldering fires as quickly as optical smoke alarms

Optical Smoke Alarms

Optical smoke alarms, also known as photoelectric smoke detectors, work by using a light sensor to detect larger smoke particles produced by slow-burning, smouldering fires. When smoke enters the detection chamber, it obstructs the light beam, causing the detector to sound the alarm.

Pros of Optical Smoke Alarms:

  • More effective at detecting slow-burning fires, such as electrical or upholstery fires
  • Less prone to false alarms caused by cooking fumes or steam

Cons of Optical Smoke Alarms:

  • May not detect fast-flaming fires as quickly as ionisation smoke alarms
  • Tend to be more expensive than ionisation smoke alarms

To ensure adequate protection in your flat, it’s important to install both ionisation and optical smoke alarms or a combination alarm that utilises both sensing technologies. Regularly test your smoke alarms at least monthly by pressing the button on them, and make sure you have smoke alarms on every floor and that they are properly maintained.

Smoke Alarm Regulations and Requirements

Landlords’ Responsibilities

Landlords in the UK must adhere to the Smoke and Carbon Monoxide Alarm Regulations when it comes to installing and maintaining smoke alarms in flats. While the regulations do not specify the type of alarms, landlords are required to ensure that:

In addition, landlords must:

  • Test all alarms at the start of a new tenancy to ensure proper working condition
  • Address and repair reported issues with smoke alarms in a timely manner

Tenants’ Responsibilities

Tenants have a role to play in maintaining the safety of their flats as well. They should:

  • Regularly test smoke alarms and carbon monoxide alarms to ensure functionality; this includes both battery-powered and mains-powered alarms
  • Notify the landlord promptly if an alarm is faulty or non-functional
  • Avoid tampering with or disabling alarms by removing batteries or improper handling
  • Familiarise themselves with the fire safety guidelines provided by the government, including escape plans and prevention measures

Following these regulations and requirements helps ensure the safety of tenants in flats across the UK, both in the private rented sector and the social rented sector. By working together and adhering to government guidelines, landlords and tenants can contribute to creating a safer living environment for all.

Proper Installation and Maintenance of Smoke Alarms

Installation Locations

When installing smoke alarms in flats, it is crucial to choose the right locations to ensure their effectiveness. Smoke alarms should be installed at least 10 feet (3 meters) from a cooking appliance to minimise false alarms while cooking [1]. Mount them high on walls or ceilings (remember that smoke rises). For wall-mounted alarms, they should be installed no more than 12 inches away from the ceiling (to the top of the alarm) [1]. It is necessary to have a smoke alarm in every bedroom, outside sleeping areas, and on every level of the flat [5].

Changing Batteries

To ensure the proper functioning of your smoke alarm, you should regularly replace the batteries. Batteries should be changed at least once a year or when the alarm starts emitting a low battery signal. If your smoke alarm is hardwired, it’s essential to still have backup batteries in case of power outages.

Alarm Testing and Maintenance Procedures

Test your smoke alarms once a month by pressing the test button on the alarm unit 3. If you have a hardwired detector, make sure to turn off the power supply before removing the alarm from its base [4]. A qualified electrician should be contacted if you encounter any issues with a hardwired smoke alarm system.

It’s crucial to follow the manufacturer’s instructions for care and maintenance of your smoke alarm. This includes regular cleaning to prevent dust and debris build-up, which can cause false alarms or hinder the alarm’s ability to detect smoke [3]. As a general rule of thumb, consider replacing your smoke alarms every 10 years to ensure optimal functioning and protection.

Advanced Alarms and Features

In this section, we will discuss various advanced alarms and features available for smoke alarms in flats in the UK. These alarms not only help protect lives but also provide additional benefits for different living situations.

Mains-Powered Alarms

Mains-powered alarms are wired directly into the household electricity supply, providing a more reliable power source than battery-operated alarms. They often come with a back-up battery in case of power outages. If you rent a flat, remember to contact your landlord if your mains-powered alarms are not working.

Linked and Interlinked Alarms

Linked and interlinked alarms offer extra protection by sounding simultaneously across multiple rooms or even adjoining flats. When one alarm detects smoke or another hazard, all connected alarms go off, ensuring residents in all parts of the building are alerted to the danger.

Specialist Alarms for Disabilities

Smoke alarms specifically designed for people with disabilities offer visual and vibrating alerts in addition to the standard audible alarms. The RNID website is an excellent source of information on smoke alarm systems for people who are deaf or have hearing loss.

Carbon Monoxide Alarms

A carbon monoxide alarm is essential for detecting dangerous levels of the poisonous gas, which can be fatal if left undetected. They should meet BS EN 50291 part 1 and display the BSI Kitemark™ symbol. Some smoke alarms systems for people with disabilities also include a carbon monoxide alarm, providing an additional safety measure.

Vibrating Pad Alarms

Specifically designed for individuals with hearing impairments, vibrating pad alarms are placed under the pillow to alert users with a strong vibration in case of fires or other hazards. These alarms can be included in some specialist alarm systems for people who are deaf or have hearing loss.

Heat Alarms and Fire Extinguishers in Flats

Heat Alarms for the Kitchen

Heat alarms are essential in flats, especially in areas where high temperatures and smoke are common, such as kitchens. These devices are designed to detect abnormal increases in temperature, providing an early warning of potential fire hazards. Unlike smoke alarms, which may produce false alarms due to cooking or steam, heat alarms are more suitable and reliable for use in kitchens.

A quality heat alarm typically uses a heat-sensitive element, which will trigger the alarm when the ambient temperature rises above a pre-defined threshold. It is crucial to install heat alarms in flat kitchens as they offer reliable protection without false alarms caused by everyday cooking activities.

Selecting a Fire Extinguisher

Fire extinguishers are an essential tool for fire safety in flats. Selecting the appropriate fire extinguisher depends on the type of fire you may encounter. Here’s a brief overview of fire extinguisher types and their uses:

  • Water Extinguishers (Class A): Suitable for fires involving solid combustibles, such as wood, paper, or textiles. Not recommended for electrical or flammable liquid fires.
  • Carbon Dioxide Extinguishers (Class B and C): Ideal for electrical fires and flammable liquids like petrol or paint. Note that CO2 extinguishers may not be suitable for kitchen fires involving cooking oils or fats.
  • Powder Extinguishers (ABC): A versatile option designed to tackle various fire classes, including A, B, and electrical fires. However, they may cause damage to electrical equipment and should be used cautiously in kitchens.
  • Foam Extinguishers (Class A and B): Effective for fires involving solid materials and flammable liquids. Less damaging to electrical equipment compared to powder extinguishers.
  • Wet Chemical Extinguishers (Class F): Specifically designed for fires involving cooking oils and fats, making them the preferred choice for kitchen fires in flats.

It is essential to ensure that the fire extinguisher is easily accessible and well-maintained. Having the right type of extinguisher, along with heat alarms, can greatly improve fire safety in flats. Regular inspections and servicing of fire safety equipment are also imperative to their effectiveness.
