Life Safety and Fire Alarm Systems

Life Safety and Fire Alarm Systems are automated early detection and notification systems designed to detect problems, notably fires, and notify the buildings population of such an event.

Fire Alarm System Installation

Thank you for considering International Signal, Inc. for your fire alarm system installation. We are one of New England's oldest alarm companies and have been in continuous operation for 57 years.

Unlike our competitors, we engineer our life safety systems in house and don't rely on expensive third party engineers. Our systems are then installed and supervised in accordance with NFPA 72 National Fire Alarm Code, National Electrical Code, and local/state laws and ordinances. Another major consideration is that we do not use proprietary equipment unless there are no other options for a particular situation.

After all, a job done right will minimize service over the years. We don't take shortcuts to maximize profit and minimize protection. We do our best with industry best practices so that your fire alarm system is reliable and provides years of trouble free service.

Fire Alarm Testing & Inspections

Lives Are at Stake! System problems and impairments may not be obvious without proper fire alarm testing and inspection. Here are six reasons why you should consider routine testing and inspection:

  • Reduced False Alarms
  • Reduced Expenses from Emergency Service Calls
  • Required by NFPA72 (National Fire Protection Agency)
  • Required by AHJ (Authority Having Jurisdiction)
  • Increases Insurance Eligibility - Your insurance provider may reject your claim if you cannot provide proof of routine testing and inspections.
  • Helps Save Property and Most Importantly - Lives
