Wireless smoke alarms selection tool launched

wireless-system-selector-toolInterlinked smoke alarms notify residents of a building if a fire breaks out in a distant room, where there could be a risk of not hearing the smoke alarm. Here is an example: a fire starts in the kitchen at night while the occupants of the house are asleep in bed. The alarm in the kitchen detects the fire and starts beeping, this message is relayed to the interconnecting alarms throughout the building to alert all occupants and will also rouse them from their sleep, allowing for a safe escape from the fire. An interlinked system for such a scenario will consist of at least one heat alarm in the kitchen and a smoke alarm in the bedroom or on the landing.

There are different ways of interlinking smoke alarms, most of them involve cabling between each unit. Wireless smoke alarms, however, do not require a cable between each alarm; they pass the signal between the different detectors as a radio frequency signal. This way of passing a signal is accepted by British Standards as an alternative to wiring between alarms.

Wireless smoke alarms,have broadly speaking, four power supply options:

The mains powered alarms, while using RF (radio frequency) signals for the communication between themselves, have, of course, some wiring for the power supply. Each of these smoke alarms is supplied with power from either the nearest light fitting or a separate mains power supply circuit.

Mains powered wireless smoke alarms fully satisfy the standard BS5839-6:2013 Grade D, however the sealed ten year power supply of the Ei600TYCRF wireless fire alarm series is usually also accepted as Grade D alternative by Building Inspectors and fire safety officers. Please ask your Building Inspector or fire safety officer before installing the ten year Ei600TYCRF series if your building requires Grade D alarms.

Each of the above smoke alarm series include a range of different fire detection sensors, usually:

  • Ionisation smoke alarms – Detect the electrical property changes of the air in case of a fire
  • Optical (photoelectric) smoke alarms – ‘See’ smoke when it enters its detection chamber
  • Heat alarms – Detect the increase in temperature from a fire

Depending from the application and the room, a specific sensor type is necessary. This can be quite confusing if you are not an expert.

To aid in this selection process Safelincs has developed a website dedicated to explaining wireless smoke alarms. We have also created a system selector tool to help you pick the correct units for your building. Just select the power supply type, enter the number and type of rooms to be protected and the system will place the correct smoke alarms into your basket.

Wireless smoke alarms in private households

Smoke alarms are some of the most important fire safety products in your home. Fires often break out after you left a room or have gone to bed. For example if you left the cooker on, left a pan on the cooker, forgot to extinguish some candles or to extinguish an open fire. Smoke alarms will notify you immediately if a fire starts and will give you valuable time to either fight the fire or flee the building. This early warning is crucial, as seconds count when fleeing from a fire, especially if you have to look after the safe escape of children as well. If your house or flat is too big to hear, for example, a heat alarm going off in the kitchen from your bedroom, you need to interlink your smoke alarms. This can be done with cable (battery or main smoke alarms are available with cable interlink) or with a wireless radio-interlink. Radio-interlinked smoke alarms communicate with each other through radio-frequency. If one smoke alarm detects fire, it passes the warning to all other smoke alarms in their system, so that all smoke alarms sound the alarm.

Radio-interlinked smoke alarms are available as ordinary battery smoke alarms, longlife battery smoke alarms with a guaranteed ten year battery life or as mains powered alarms.

Wireless smoke alarms can also be used in any outbuildings your home may have, like sheds, garages or workshops. You can expand the alarms’ coverage quickly and easily as and when you need to add new alarms.

Like any other smoke alarms, wireless smoke alarms need to be regularly tested to ensure that they are fully operational.

You can buy your wireless smoke alarms indiviually or in home fire safety kits, which reduce the cost of fire safety provision.

New radio-interlinked smoke alarms from Kidde

Kidde have added mains powered radio-interlinked smoke alarms to their range of 230V smoke alarms. The new slimline design offers customers an additional choice in our smoke alarm range. The alarms conform to BS5839-pt6 grade D, E and F and are installed in new residenatial conversions and extensions, small to medium offices and many HMOs.

The Kidde Slick smoke and heat alarms can be wired from the nearest light fitting, making them cheaper to install and less intrusive than other hard wired smoke alarms. They are fitted with an alkaline back up battery as standard but this can be upgraded to a 10 year lithium battery if required.  The alarms have a unique fast-fitting base and a screwless connection block making installation as easy as possible.

The units talk to each other through a wireless connection. This means that when one alarm detects fire all the alarms will be activated and begin to sound within seconds. Up to 15 alarms can be interlinked together in one system and the   house coding process is very simple.

With their new design Kidde have really thought of everything: the alarms are fitted with an LED that will enable you to identify the initiating smoke alarm.  The alarms also have a flashing LED that will give you silent notice for 30 days that the batteries are getting low. After this 30 day period the alarms will then give off the usual warning chirp.
