What are interconnected smoke alarms?

For extra peace of mind, enable app notifications to receive alerts even when away from home. With comprehensive detection and impossible-to-miss alerts covering every room, our interlinked safety systems provide 24/7 security so your family is always protected.

Frequently Asked Questions

  • Why should I buy interlinked smoke alarms?

    • Faster fire detection and escape: Early warning is crucial in a fire, and interlinked alarms provide that by alerting everyone in the house, no matter their location.
    • Increased safety for everyone: Interlinked alarms are especially important for multi-story homes or those with sleeping areas far from the kitchen (common fire origin).

  • What types of interlinked smoke alarms are available?

    • Smoke alarms: Detect smoke particles from burning materials.
    • Heat alarms: Detect heat from a fire, ideal for kitchens where smoke might not be the first sign.
    • Smoke & Heat alarms: Combine both smoke and heat detection for the most comprehensive protection.

  • Do the fire brigade fit smoke alarms for free?

    The Scottish Fire and Rescue Service (SFRS) does not generally fit smoke alarms for free in owner-occupied homes. However, they may offer free assistance to vulnerable individuals or households who are identified as "high risk" through their Home Fire Safety Visit assessment.


    Here's a summary:


    • Most homeowners need to purchase and install alarms themselves.
    • SFRS offers free Home Fire Safety Visits:

    They assess fire risks and provide safety advice.

    They provide interlinked alarms for free to high-risk individuals/households.


    If you don't qualify for free fire alarms Scotland, you can find information about the new standards and compliant alarms on the SFRS website: https://www.firescotland.gov.uk/

  • What types of housing are covered by the new fire alarm standard in Scotland?

    All homes in Scotland are covered by the new standard, regardless of the type of housing (owned, rented, etc.). This ensures everyone has the same level of fire protection.

  • I already have smoke alarms, do I need to change them?

    The answer is yes. Standard alarms which are not interlinked will not be compliant with the new law, they will need to be replaced with a series of new interlined alarms to adhere to the new law. 

  • Guarantee & Battery Life

    Our alarms come with a 5-year guarantee and include long-lasting batteries (typically lasting at least 10 years). This ensures your alarms are protected and operational for an extended period.

  • Do I need an Electrician for installation?

    No, you don't necessarily need a qualified electrician to install our alarms. They come with easy-to-use cradles and screws for self-installation.

  • Hardwired smoke alarm option & cost

    While not required, you can choose hardwired installation by a qualified electrician. This option typically costs up to £2,000.

  • Installation ease

    Installing our alarms is simple and straightforward. You simply screw the provided fixture into the ceiling and then twist and click the alarm unit into place.
