Whether you are looking for a battery powered smoke alarm, a radio-interlinked smoke alarm system or mains-powered smoke and heat alarms we have smoke detectors that will meet your needs. We offer Grade F and D smoke and heat alarms.
Powered by a 10 year sealed lithium battery and featuring an optical smoke sensor specially designed to maximise smoke detection and minimise false alarms, this alarm provides top-class standalone protection.
Battery: 10 year sealed lithium battery
Warranty: 10 year manufacturer's warranty
Optical smoke sensor suitable for hallways, landings, living rooms, and bedrooms
Ideal for rooms like garages, kitchens, and lofts where dust or fumes would cause false activations of smoke alarms, the UltraFire ULLH10 features a sealed 10 year battery and 10 year manufacturer's warranty.
The UltraFire ULLH10RF features a sealed 10 year battery and wireless interlink with up to 15 total alarms to alert the whole house of a possible fire emergency. Ideal for kitchens, garages, basements, and lofts.
Mains powered smoke alarms are powered by the electrical circuit of a building, are interconnected and are mainly used in residential new builds, rented accommodation and smaller commercial applications. They should always contain a backup battery to ensure that if a fire is started by an electrical fault which cuts the power supply, the alarm will still detect the fire. These backup batteries can be of a replaceable type (eg alkaline) or of a sealed-in, re-chargeable type (trickle charging). The power supply, if retro-fitted, is usually taken from the nearest light fitting.
These smoke detectors have integrated RF senders and receivers. If one smoke alarm detects a fire, it passes this information to all other alarms within the same group of alarms to raise the alarm in the entire building. Perfect for larger houses and smaller commercial applications. Some of the RF smoke alarms have sealed longlife batteries as the only power supply, making them an alternative to mains powered smoke detectors (Building Control might have to be asked for a clarification first)
Ionisation Smoke Alarms detect changes in the electrical charge of particles in the air within their sensor chamber. They were particularly well suited for 'invisible' or fast-flaming fires, such as paper or dry wood fires, which can give off very little smoke despite having an active flame. They were sadly also very sensitive to burnt toast, which is why they should not be installed near kitchens. Historically, ionisation smoke detectors have been recommended for landings and office spaces, but the technology behind optical smoke alarms advanced to the point that they are interchangeable.
Safelincs has stopped selling ionisation smoke alarms, and we would encourage all of our customers to purchase optical smoke alarms instead. Optical smoke alarms are not potentially hazardous like ionisation technology, due to not using radioactive elements.
Heat alarms, as the name suggests, measure temperature rather than detect smoke. They raise an alarm if the temperature rises above a certain point or if the temperature rises rapidly. They are suitable for kitchens and garages as they will not cause false alarms. It is important to know that they only cover small areas and a kitchen or garage might require several heat detectors for full cover.
Optical or photoelectric smoke detectors 'see' smoke when a very small permanent light beam within the alarm is affected by smoke. They are ideal for smouldering fires producing smoke rather than heat, such as burning soft furnishings and electrical equipment. They are less prone to false alarms from burnt toast, so can be used near kitchens (not in kitchens, though). We recommend optical smoke alarms for hallways, dining rooms, living rooms, bedrooms.
