Notifier or Notifier Fire Control Systems is a manufacturer of engineere fire alarm systems with many distributors worldwide, and regional support operations on every continent. It is located in Northford, Connecticut and is a division of the Honeywell company. Notifier has been producing fire alarm equipment for over 50 years, including fire alarm control panels, network systems, system integration, peripheral devices, accessories, and gas detection. Many of Notifier's products range from manual pull stations, fire alarm control panels, and smoke detectors to be integrated with fire alarm systems. They do not make fire alarm notification appliances, however, so fire alarm signals manufactured by System Sensor, Cooper Wheelock, and Gentex are often used with their systems. System Sensor is the main supplier of devices such as horns, strobes, horn/strobe combo's, detectors [heat and smoke], sprinkler devices [water flow switch, tamper valve switch, low air/water pressure switch].
