New Hampshire Security & Fire Alarm Service Areas

Find your community and the service you need

The security guides cover homes, businesses, cameras and controlled entrances. The fire guides address commercial system design, alterations, monitoring, acceptance and ongoing service. Choose the service that matches the work rather than using a residential security estimate to budget a commercial fire project.

A 2026 code change worth checking before design begins

The NH Fire Marshal’s current fire-code notice identifies the 2024 editions of NFPA 1 and NFPA 101, with state modifications, effective July 27, 2026. Separately, the state building-code notice allows building-permit requests under the 2021 or 2024 codes through December 31, 2026, with the new listed codes required from January 1, 2027. The building and fire changes have separate timelines; ask the project team to document which requirements apply to your permit.

There is also a change in local authority. Effective July 1, 2026, RSA 153:5, paragraph V permits municipal administrative fire-code amendments, such as permits and fees, while prohibiting amendments to the state fire code’s technical requirements. SB 94, enacted as Chapter 17 of 2026 addresses technical amendments to the building code as well.

This is a reason to resolve scope early, not to skip permits or omit a safety function. The town guides distinguish dated documents from current procedures where the available evidence allows. Requirements for a particular occupancy, interface or existing building still need project-specific review.

Choose a system around the building and its users

The local guides focus on conditions that can change a design: an older finished interior, a shared residential entrance, a coastal rental, a loading area or a tenant space within a larger building. A town-wide crime statistic or median home value cannot specify an alarm package.

• Finished walls and additions: inspect existing circuits and practical cable routes, then test proposed wireless locations. Avoid assuming that either all wiring is reusable or every radio path will work.
• Several users or tenants: separate permissions, notification recipients and responsibilities. The people who administer access should be defined before handover.
• Seasonal or unattended space: identify power, communication and environmental-alert dependencies, and name someone who can physically check the property.
• Commercial alterations: coordinate the base-building system, affected devices and other trades. A small floor-plan change can still affect notification, monitoring descriptions or the acceptance scope.

For wiring choices, see wireless versus hardwired security systems. For a commercial system already in service, the NH fire alarm inspection guide explains recurring testing and documentation.

How Cunningham supports New Hampshire properties

Our NH work is coordinated through the Portsmouth operation, with support from the wider regional team, including Topsfield for southern New Hampshire. Field-service assignments depend on the property, system expertise, scope and schedule. Share the full address so the appropriate team can assess the work.

The Portsmouth office is at 170 Commerce Way, Suite 200, Portsmouth, NH 03801. Call (603) 431-8700 before arranging a visit. The Topsfield office also supports southern NH communities.

Cunningham has served New England since 1983. Your proposal should make clear what we will install or retain, what monitoring includes, what needs approval, and how service will be handled. Around-the-clock monitoring and an onsite service appointment are different parts of that support.

Make your first conversation more productive

1. Identify the property and goal. Send the address, property use and whether you need a new system, an upgrade, monitoring or help with a recurring problem.
2. Share what is already there. Panel photographs, model numbers, inspection reports, drawings and known faults help define a useful starting point. Do not send alarm codes or passwords through the quote form.
3. Explain the schedule and users. Include occupancy dates, renovation work, access restrictions and who will manage the system.
4. Request a complete scope. Ask the proposal to separate equipment, installation, permits, testing, monitoring and optional features. Confirm what information the project still needs before approving work.
