What is involved in fire alarm servicing?

Fire maintenance involves regular checks and servicing of fire safety equipment. This ensures that all systems are functioning correctly and comply with safety regulations. Our skilled fire alarm engineers can quickly identify and fix fire alarm system issues that may be jeopardising safety on your premises. UK fire alarm regulations state that you must have a fully-functioning alarm system if the public are inside your building. If a fault occurs with your fire alarm system, you need to report it immediately to a fire alarm repair and maintenance specialist.

It is recommended that fire equipment be serviced at least annually. However, specific requirements may vary based on local regulations and the type of equipment. Regular inspections help identify potential issues before they become serious. We work with the leading fire and smoke alarm brands (including Gent) and our engineers have the knowledge and expertise to make your premises legal and compliant again.

Compliance standards refer to the legal requirements that fire safety equipment must meet. These standards ensure that all fire systems are effective and reliable. Adhering to these regulations is essential for safety and legal protection. Our team of fire alarm repair, servicing and maintenance engineers are among some of the most experienced in the industry. With decades of expert know-how, we’re familiar with most brands of commercial fire and smoke alarm systems. 

We are licensed to install, repair, service and test your VESDA (Very Early Smoke Detection Apparatus) fire alarm system. This is a brand of advanced aspirating smoke detection systems renowned for their exceptional sensitivity. VESDA smoke detection systems are capable of detecting minute levels of smoke or combustion particles long before visible signs of fire occur. If servicing of a conventional system is problematic, or aesthetics are a major consideration, a VESDA system can be an ideal solution for you. Any commercial property where you might be in need of extremely early smoke detection might warrant a VESDA system, such as hospitals, schools and care homes.

The fire alarm testing process involves a thorough examination of fire safety equipment to ensure it operates correctly. Servicing includes checking of extinguishers, emergency lighting systems and heat and smoke detectors. We also check every call point, system logs, fire panel logs and back up fire alarm batteries. Certification is provided upon successful completion of testing.

Our fire alarm repairs service is also valuable for building managers of office blocks, retail stores, schools, sports centres or apartment blocks. If there’s a problem with your fire alarm like the panel needs fixing, the sounder’s not working or your smoke detector needs replacing, our skilled repairs and service engineers can help. Our team is made up of fire safety specialists with decades of experience.
