Proud to offer Edwards Fire Detection Systems

Fire Alarm and Evacuation Systems otherwise known as Fire Alarm Systems are the first line of defense against the devastating effects of a fire. These systems work 24 hours per day to alert building occupants of fire danger and assist in their orderly and safe evacuation. Fire Alarm Systems also help to contain the smoke and alert authorities of the danger. Lives can be saved, as well as critical business assets, by providing instant notification to authorities as soon as possible.

IntraWorks designs, installs, and services Fire Detection and Evacuation Systems for a wide variety of clients to include: government organizations, higher education, K1-K12, laboratories, manufacturing facilities, infrastructure facilities, hospitals, hotels, high rise buildings, auditoriums, casinos, parking structures and correctional institutions.

Basic Function

Fire Alarm and Evacuation Systems make-up an important part of any intelligent building or safety system by providing detection of fire and smoke, evacuation of building occupants, control of fire dampers and doors, recall of elevators, evacuation of smoke, and communication to the authorities. Fire Alarm Systems utilize hard wire to connect field devices to the main alarm control panel and remote annunciators. Field devices might include: smoke detectors, heat detectors, pull stations, smoke beam detectors, air sense detectors, carbon dioxide detectors, water flow detectors, tamper switches, horn strobes, speaker strobes, door closers, elevator recall relays, HVAC damper control systems and more.

By law, Fire Alarm Systems must alert or call a monitoring facility either operated by the organization or operated by an independent company who then dispatches according to a call list. The Fire Alarm System makes the call to the monitoring facility through phone lines, the internet, radio systems, or cellular systems. Most of the time, the Fire Alarm System utilizes more than one technology to assure reliable communication of the fire signal. The monitoring facility is an integral part of the Fire Alarm and Evacuation System solution. Please see monitoring services under the service section.

The design, installation, and maintenance of a Fire Detection and Evacuation System is mandated by fire code. Fire codes are different in each State and City and the code is more or less strict depending on the type of occupancy of the building. Changes to a building structure can effect the operation of a Fire Alarm System and must be approved by fire authorities.

New Trends

Notification Code

Fire Detection and Evacuation Systems are being modified to do more than just evacuate for fire. They are being redesigned to evacuate for other reasons such as work place violence, floods, weather related events, and much more. In addition, these systems are being utilized to announce to the building occupants that they should stay in the building in the cases of some types of weather events, active shooter events, terrorist events and more. This trend will happen over a long period of time as jurisdictions begin to adopt new fire codes, which are now referred to as notification code.

Fire Alarm Systems are also being utilized to make emergency announcements to the occupants of a building. As a result, horn strobes are being replaced with speaker strobes so that verbal instructions can be announced instead of just sirens, which provide little information.

Carbon Dioxide

Many jurisdictions are beginning to require the fire system to sense the level of carbon dioxide in a area of assembly. Once sensed, fans can evacuate the carbon dioxide keeping the occupants safe.


Fire Alarm Systems integrate to elevator control systems to recall elevators, magnetic magnetic fire door holders and closers, HVAC dampers, access control to release doors, fire suppression systems (both wet and dry), and smoke control systems for evacuation of smoke.

Many access control and building automation systems monitor the alarms generated by the Fire Alarm System in order to provide situational awareness to the command and control centers.
