Home fire and CO protection · Maine, New Hampshire & Massachusetts
Home fire alarms and carbon monoxide protection
A fire or carbon monoxide emergency can happen while you are asleep or away. Cunningham Security designs, installs, services and monitors residential detection systems, with equipment and notification planned around your home.
Alarm sounding or a possible emergency? Get everyone outside and call 911 from a safe location. Do not wait for an app alert, a monitoring call or a service appointment. Stay outside until emergency responders say it is safe.

Serving New England since 1983, we help homeowners add monitored detection, assess older equipment and understand what their present system actually covers. If a device needs attention now, contact our team for service.
An alarm at home, with a path to help when you are away
A household smoke alarm warns people nearby. Interconnected alarms extend that warning through the home. Professional monitoring adds a separate communication path: enrolled fire or CO devices report through a compatible alarm system to the monitoring center, which follows the established emergency response procedure.
Cunningham provides 24/7 professional alarm monitoring. During setup, we establish the protected address, clear device locations and account contacts, and test the alarm signals. Supported app notifications can provide additional awareness, but a phone notification and a monitored emergency signal are different functions.
Monitoring does not replace working in-home warning devices or your escape plan. Power, communication and equipment condition all matter. We explain the backup arrangements and which trouble signals the installed system can report; no system can guarantee detection, successful transmission or a particular emergency response time.
“I just want to let you know, your system saved my family's life last night...”
Different hazards need different detection
Smoke detection
Smoke alarms and detectors respond to airborne products of combustion. Bedrooms, sleeping areas, floors and the way rooms connect shape the coverage plan. A smoke-only device does not detect a carbon monoxide leak.
Carbon monoxide detection
CO is an invisible, odorless gas associated with fuel combustion. Detection deserves attention around sleeping areas and in homes with fuel-burning equipment or an attached garage. A CO alarm is not a propane or natural-gas leak detector unless it is specifically designed for those gases.
Heat detection
A heat detector responds to temperature conditions. It may suit an approved application where smoke detection would be unsuitable, such as some garage environments. It does not replace required smoke alarms in sleeping or living spaces.
Combination devices
A listed smoke/CO device can cover both hazards where its installation instructions and the home's requirements allow. “Combination” does not establish every function: smoke/heat and smoke/CO are different products.
Our smoke-versus-CO guide explains the choices. For a heating-season checklist, read about winter carbon monoxide risks.
A useful design considers who needs to hear the alarm
Device count is only one part of the discussion. A bedroom over a garage, a finished basement, a long hallway or an addition can change the layout. Closed bedroom doors, sleeping arrangements and hearing needs also affect how warning should be provided. Tell us if anyone needs compatible visual or tactile notification rather than relying on a standard sounder alone.
The U.S. Fire Administration recommends smoke alarms in every bedroom, outside each separate sleeping area and on every level, including the basement, with interconnection so one alarm activates the others. The exact design must also follow the selected equipment's instructions and the requirements that apply to your home.
For an older finished home, wireless system detectors may reduce the need to open walls. Where suitable wiring already exists, retaining it may be practical. We assess the installed equipment, radio coverage, available power and maintenance needs before recommending either approach.
Can we use the alarms already in your home?
First, we identify what you have. A 120-volt interconnected smoke alarm, a low-voltage system detector and a wireless security-system detector can look similar but connect differently. Sharing a brand name, mounting base or app does not establish compatibility.
- If you already have a security panel: we check the panel and receiver model, existing fire/CO zones, device ages and monitoring arrangement.
- If you have interconnected household alarms: we determine whether an approved integration is suitable or separate system detection is needed. We do not assume the interconnect wire can simply be connected to a security panel.
- If the equipment is older: we separate a battery issue from an expired detector, unavailable replacement or broader system limitation.
- If you recently bought the home: we can assess equipment whose service history or monitoring status is unclear. A keypad that powers up does not confirm active monitoring.
Keep existing required alarms working while any change is planned. For household smoke alarms, ten years from manufacture is the usual replacement point; system detectors and CO devices require model-specific review. See our alarm replacement guide.
What to include in your request
| Tell us | How it helps |
|---|---|
| Town, number of floors and sleeping areas | Sets the starting scope and identifies additions, basement rooms or separate areas that need review. |
| Existing panel and detector models | Helps us evaluate reuse, replacement and monitoring compatibility. Clear photos of accessible labels are useful. |
| Fuel equipment and attached garage | Brings CO concerns into the plan. Heating-equipment inspection remains a separate job for the appropriate qualified technician. |
| Year-round or seasonal use | Helps plan contacts, communications and maintenance when the home is unoccupied. |
| Accessibility needs or upcoming work | Lets us discuss suitable notification, renovation timing and any approval requirements early. |
A seasonal home needs particular attention to winter power and communications. Tell us if you switch off internet service or reduce heat when away. We can also discuss freeze, leak and other environmental monitoring, which addresses separate property concerns.
Keep protection useful after installation
Follow the written test and maintenance instructions for your equipment, act on trouble messages and keep your contact list current. Coordinate tests of monitored devices with the monitoring provider first; a button test may transmit an alarm on some systems.
For an occasional maintenance chirp, use our smoke alarm chirping guide. For emergency preparation, review what to do if your house is on fire. Never disable protection to stop an unexplained alarm.
Make the next step specific to your home
Whether you need a new system, monitored CO detection or an assessment of existing equipment, tell us what is installed and what concerns you. We will help define the work and the monitoring options.
