Frequently Asked Questions

❓ My house is a detached single-family home, do I need to install a sprinkler system?

Whether a detached single-family home requires a sprinkler system depends on the number of stories and the total floor area. Generally, detached homes with 5 stories or fewer do not need automatic sprinkler systems. However, residential buildings with 6 or more stories, or those exceeding 50 meters in height, do require them. It’s recommended to consult a professional fire protection engineer for an assessment and consider installing residential fire warning devices to enhance safety.

❓ If my renovation is minor, do I need to reapply for fire safety review?

Whether a minor renovation requires a new fire safety review depends on whether the renovation affects the performance of existing fire safety equipment. If the renovation does not involve changes to fire compartmentation, does not impact alarm system performance, and does not alter existing evacuation routes, a new application is typically not needed. However, if the renovation affects the function or location of fire safety equipment, a permit for alteration must be obtained according to regulations.

❓ Old buildings without sprinkler systems, must they be retrofitted during renovation?

Whether sprinkler systems must be added during the renovation of old buildings depends on the extent of the renovation and the building’s characteristics. If the renovation does not involve a change of use and does not reach a certain scale, it may fall under existing building improvement regulations. However, if the use changes or the scale expands after renovation, fire safety equipment must be reviewed according to current regulations. Consulting a professional for an assessment is advised.

❓ Smoke detectors are prone to false alarms, are there alternatives?

If smoke detectors frequently trigger false alarms, consider these alternatives: 1) Opt for photoelectric spot-type smoke detectors to reduce false alarms from cooking smoke; 2) Use fixed-temperature detectors in areas prone to false alarms, such as kitchens; 3) Employ combination detectors that integrate smoke and heat detection. Most importantly, ensure proper installation and regular maintenance to minimize false alarms.

Safety First: The Importance of Correct Fire Safety Equipment Installation

The correct installation of fire safety equipment is not just a regulatory requirement; it is a critical measure for protecting lives and property. When undertaking interior renovations, it is essential to understand the relevant fire safety regulations and, when necessary, consult with professionals to ensure that fire safety equipment complies with standards and functions correctly.

Remember: Investing in fire safety equipment is an investment in security. Proper planning and installation play a crucial role during a fire and deserve our utmost attention and commitment.
