We recently completed a full fire alarm upgrade at a residential block of flats in Penn Hill, replacing an outdated system with a modern, compliant, and more practical solution for both the building owner and residents.
The Challenge
The existing fire alarm system was no longer fit for purpose, with non fire-resistant cabling installed throughout the property. This posed a compliance and safety concern, particularly in a multi-occupancy building where early detection and safe evacuation are critical.
Due to the layout and finished condition of the building, the client did not want surface containment installed, which ruled out a traditional hardwired upgrade.
The Solution
To overcome this, we installed a wireless EMS SmartCell fire alarm system. This allowed us to upgrade the entire system without the need for disruptive cabling or visible containment, while still achieving full compliance.
The installation included:
- Wireless EMS SmartCell fire alarm panel
- Heat detectors installed within each individual flat
- Smoke detectors throughout communal areas and escape routes
- Manual call points positioned in key locations including lobbies and near exits
- Detection within the electrical cupboard for added protection
This setup ensures full coverage where it matters most, particularly along escape routes and areas where a fire is most likely to impact evacuation.
System Classification – Grade A, Category L3
The system installed meets Grade A Category L3 standards.
- Grade A refers to a full fire alarm system with control panel, detectors, sounders, and standby power supply
- Category L3 systems are designed to protect escape routes, with detection in corridors, stairwells, and rooms opening onto those routes
The aim of an L3 system is simple: provide early warning so occupants can safely escape before smoke or fire blocks exit routes
This makes it ideal for blocks of flats and HMOs where protecting communal escape routes is essential.
AOV Integration
As part of the upgrade, the system was integrated with the building’s AOV (Automatic Opening Vent) window.
- On alarm activation, the AOV automatically opens
- This helps clear smoke from escape routes
- Improves visibility and reduces risk during evacuation
This is a key safety feature in multi-storey residential buildings.
The Result
The end result is a clean, modern, and fully compliant fire alarm system that:
- Meets current regulations
- Minimises disruption to the building
- Provides reliable, early fire detection
- Enhances overall life safety for residents
By choosing a wireless solution, we were able to deliver a high-standard installation without compromising the finish of the property.
If you’re managing a block of flats or concerned about your current fire alarm system, upgrading to a compliant solution like this can make a huge difference in both safety and practicality.
