Fire Alarm System Installation
Every building is different, which means every fire detection system should be designed with its layout, risks, occupancy, fire strategy and future maintenance in mind.
We install modern, reliable fire alarm systems suitable for a wide range of commercial and managed environments, including:
- Offices and commercial premises
- Retail premises and hospitality venues
- Warehouses and industrial units
- Schools and education buildings
- HMO and rental properties
- Public buildings and community facilities
- Small business units and mixed-use premises
A fire alarm installation may include detectors, manual call points, sounders, control equipment, batteries, cabling or wireless devices, commissioning support and user handover depending on the system design.
We mainly install Ajax EN54 and C-TEC fire alarm systems, with the right option selected around the building, cable routes, disruption, category requirements, budget and ongoing maintenance needs.
Our installation process can include:
- Site survey and system design
- Selection of suitable Ajax EN54 or C-TEC equipment
- Detector and manual call point positioning
- Sounder coverage and audibility considerations
- Control panel installation and system setup
- Commissioning support and user handover
- Ongoing servicing and maintenance options
The result is a practical fire detection system that is easy to use, professionally installed and suitable for the building it protects.

Fire Alarm System Upgrades
Many properties still rely on older fire alarm panels that may be difficult to maintain, no longer suit the building, or are approaching end of life.
Replacing or upgrading an outdated fire alarm system can improve:
- Reliability
- Detector compatibility
- Availability of replacement parts
- Ease of maintenance
- System usability for staff
- Support for current fire safety arrangements
Sanders Secure can review existing fire alarm systems and recommend practical upgrade options using Ajax EN54 or C-TEC equipment where suitable.
Fire Alarm Servicing in Plymouth
Like any life safety system, fire alarms should be serviced regularly to confirm they operate correctly when needed. Sanders Secure provides professional fire alarm servicing in Plymouth for businesses, landlords and managed premises.
A fire alarm service visit can include inspection of the control panel, testing of selected detectors and manual call points, sounder activation checks, battery condition checks, fault investigation, logbook updates and clear recommendations where issues are found.
Regular servicing helps confirm the system is operating as intended and supports the responsible person in managing ongoing fire safety arrangements.
For more detail on routine servicing, testing, maintenance and fault support for existing systems, visit our dedicated fire alarm servicing in Plymouth page.
Fire alarm servicing can also be arranged alongside emergency lighting servicing in Plymouth where suitable, helping responsible persons keep safety system checks more organised.

Fire Alarm Testing in Plymouth
Searches for fire alarm testing often come from customers who already have a system installed and need it checked, serviced or documented properly.
Sanders Secure provides fire alarm testing in Plymouth for commercial premises, landlords and managed buildings. Testing may include activating selected devices, checking sounders, reviewing panel faults, confirming battery condition and making sure the system is operating correctly at the time of visit.
We also provide clear service documentation and practical recommendations if faults, ageing equipment, poor coverage or maintenance concerns are identified.

Fire Alarm Compliance & Safety Standards
Fire alarm systems should be designed, installed, commissioned and maintained in line with the relevant standards and the needs identified by the responsible person’s fire risk assessment.
- BS 5839-1:2025 – fire detection and fire alarm systems for non-domestic premises
- BS 5839-6 – fire detection and fire alarm systems for domestic premises, where applicable
- Regulatory Reform (Fire Safety) Order 2005 – duties for responsible persons in non-domestic premises
Sanders Secure does not replace the need for a suitable fire risk assessment, and we do not provide legal compliance advice. We can, however, install, service and maintain fire alarm systems that support your fire safety arrangements and help responsible persons manage their duties more confidently.
