Smoke alarms and detectors

Smoke detectors and alarms.

Smoke alarms or detectors are devices that are able to detect smoke or fire, giving an audible alarm as a result. They are fantastic at detecting a fire in its early stages, allowing you adequate warning to evacuate before inhaling any harmful gases. Smoke inhalation is the primary cause of fatality when it comes to fire-related deaths. In fact, in the majority of cases, the victims are asleep when the smoke enters their lungs, cementing the absolute requirement for smoke alarms.

Heat detectors and alarms

Heat alarms are installed in kitchens and garages, where smoke or fumes are part of the atmosphere, to prevent false alarms.

CO2 detectors and alarms

Carbon monoxide (CO) has been called the "silent" and "invisible killer" because it's a scentless, colourless, and tasteless toxic gas. Any time you burn something like petrol, natural gas, wood, oil, propane, or charcoal carbon monoxide is released into the air. In outdoor spaces, this usually isn't a health hazard because there is enough area to dissipate and particles never amount to a toxic level. The danger comes when carbon monoxide is released in a  contained area like your home.

Smoke and heat alarms provide a vital early warning and can allow extra time to escape if there is a fire in your home. Ideally you need multiple, linked smoke alarms for your property to be properly covered. For example, if a smoke alarm is only fitted in the hallway, should a fire start in the bedroom the occupant's life may already be at risk before the alarm would   activate. Since October 2015, landlords are legally required to install smoke alarms in rental properties and could face fines of up to £5000 if they fail to comply. There are many different types of smoke alarms available including strobe light and vibrating-pad alarms for those who are deaf or hard of hearing, joint smoke and carbon monoxide alarms, and mains-powered alarms.
