Nortech Systems (Nortech) provided fire alarm design services to safeguard the apartment complex at 34 Madbury Lane in Durham, New Hampshire. Nortech designed a replacement fire alarm system for the three-story building. The system includes initiation by manual pull stations, sprinkler monitoring, and automatic detection in the form of smoke, heat and carbon monoxide (CO) detectors. Once initiated, the system was designed to go into alarm, initiate elevator recall, shutdown applicable equipment and notify occupants of an emergency. Local occupant notification consists of both audible and visual notification. Devices are comprised of horns and strobes, including low frequency horns and 177 candela strobes in sleeping spaces. The system provides annunciation by utilizing the existing fire alarm control unit and interior annunciator. It’s also connected to an existing radio box to alert the local fire department of a fire scenario.
The fire alarm system was designed in accordance with the State of New Hampshire Building Code (RSA 155-A). Specifically, the International Existing Building Code (IEBC-2009). It was also designed to comply with the State of New Hampshire Fire Code (Saf-C 6000). Including, but not limited to, the National Fire Alarm and Signaling Code (NFPA 72-2013) and the Life Safety Code (NFPA 101-2015).
