As part of the Davis-Ulmer Family of Companies (since 2021), we bring you expanded resources and specialized support, while keeping the responsive, personalized service our customers have always trusted. With 100+ dedicated professionals, we deliver complete life safety solutions, from routine inspections to complex system design and installation. We make sure you are protected 24/7.

Fire Sprinkler Installation

Trusted Designs. Code-Compliant Installs. We design, install, and service fire sprinkler systems that protect lives and property, whether for new construction or retrofits. We deliver efficient, code-compliant designs and are licensed by the State of Maine Fire Marshal’s Office.

Fire-Fighting Foam

Foam/water systems protect large flammable-liquid hazard areas by combining water discharge with AFFF or high-expansion foam to cool and smother fuel spills. Common applications include aircraft hangars, fuel depots, and flammable-liquid storage. These systems are triggered by dedicated, highly sensitive detection, and discharged foam solution can be contained and safely removed.

Eastern Fire provides design, fabrication, and installation of foam systems—contact our specialists to select the right solution for your hazard.

Fire Suppression Systems

In addition to wet, dry, and deluge sprinkler systems, Eastern Fire provides clean agent suppression for computer rooms and other sensitive areas. We also install hybrid nitrogen/water systems for museums, libraries, data centers, and power facilities, as well as CO₂ systems for enclosed, unoccupied spaces such as machinery rooms and electrical cabinets.

Fire Alarm Systems

Eastern Fire is a licensed distributor for Siemens, trusted manufacturers of advanced fire alarm systems. Our factory-trained Alarm Technicians—also licensed Electricians—are fully qualified to support your fire alarm needs.
We install and maintain both conventional and addressable systems. Addressable systems provide greater flexibility, easy expansion, precise fire location by floor/room/device, and built-in self-diagnostics to help reduce service calls.

Gas Detection Systems

Gas detection systems are essential for medical, chemical, and industrial facilities to protect employees and property. Unlike natural gas, which contains additives to make leaks easier to detect, many hazardous gases and vapors are invisible and odorless, making reliable monitoring critical to preventing injury, loss of life, and equipment damage. Gas detectors may be fixed or portable and require regular calibration and testing to ensure proper performance. Our specially trained and qualified technicians provide these vital services, and we sell and install the ENMET line of gas and vapor detectors.

Backflow Prevention

Protect your drinking water with reliable backflow prevention. A properly working backflow preventer keeps contaminated water from reversing into your clean water supply. If it fails or becomes blocked, serious plumbing issues can result.
Eastern Fire’s certified technicians, trained by New England Water Works Association, test, service, and maintain mechanical backflow valves to keep them operating properly. We offer 24-hour service.
