Fire alarms, burglar alarms, and intrusion detectors are the three most common alarm systems.
In the UK, a house alarm can typically sound for up to 20 minutes before it automatically shuts off, in compliance with noise pollution regulations.
A professional installer will cost you between £40 and £75. Professional electrician installation is required for mains-powered alarms (ranging in price from £65 to £250). The average price to have one installed is between £75 and £125. Modern fire alarms can communicate with your smartphone.
