Advantages: No need to keep replacing batteries Disadvantages: You need a suitable light fitting in the right place.
I am sure we all know that smokealarms for the home are a great idea but unless you live in a new home and have one wired in then you need to remember to replace the batteries regularly. My smokealarms are now quite elderly (20 years+) so I started looking at the options.
I discovered that there are more than just one type of smokealarm. There are two basic systems according to the Fire Service:
?Ionisation: These are the cheapest and cost very little to purchase. They are very sensitive to small particles of smoke produced by flaming fires, such as chip pans, 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.
?Optical: These are more expensive but more effective at detecting ...
Advantages: Saves yours and your families life. Easy to install Disadvantages: None that i can think of.

feet from any inside corner.
- Put smokealarms at both ends of the bedroom
hallway or large room if the hallway or room is
more than 30 feet long.

Advantages: Barely noticeable looks, no batteries to change, illuminates lights to help escape Disadvantages: May suddenly turn the bedroom light on at 2am if there's a power cut
This is an excellent solution to having unsightly smokealarms on the ceiling.
The Housesafe smokealarm replaces the normal pendant light rose on the ceiling and the smokealarm and sensors are concealed in the base.
It is wired into the mains like a normal pendant light would be and once smoke has been detected, the siren activates and automatically illuminates the pendant light to provide an illuminated escape route.
In the event of a mains power failure, the alarm is still operational via a rechargeable battery contained within it and it contains a power monitoring supply system to ensure 100% effectiveness.
