Fire Alarm Design: Requires the Services of a Competent Engineer
By Arthur Sneddon

Fire alarm systems are used as active fire protection systems to control all the components of a fire alarm within a building. Fire alarms require stringent bounding and the fire alarm design should be performed by a competent engineer or engineers that are licensed in close proximity of the area of practice. Whenever the fire alarm needs extension, it is these designs that need to be used as a basis to match existing specifications. The fire alarm design allows the manufacturer of fire alarm systems to make products that are suited to different needs and, a good fire alarm system will necessarily be the end product of good design work. To get the best in fire alarm design, a company or manufacturer will need to employ fire alarm technicians as well as designers that are certified by the National Institute for Certification in Engineering Technologies (NICET).

What Needs to Be Included in a Fire Alarm Design?

Fire alarm design drawings need to indicate at the very least, the location of devices, the heights of such devices, size of wires, conduit, zones, location of risers as well as spare capacities of audio as well as visual circuits. In addition, the designer should get his or her fire alarm designs approved by the AJH, prior to setting it into practice. The fire alarm design should make it possible to have fire alarm systems that may even need to have microprocessor control as well as be able to provide intelligent reporting. The fire alarm system may also need to be operated on a single stage principal and, another feature of the fire alarm design may be the incorporation of digital voice messaging as well as cater to incorporation of future expansion capabilities to include such features.

The fire alarm design may need to incorporate dedicated individual conduit systems as well as risers that have fire fighter telephones, voice communication, visual signal appliances, initiating as well as monitoring devices, and network data communication. In addition, the fire alarm design may also need peer-to-peer network configuration, especially in buildings that have more than eight stories in height or, buildings that have more than 500 initiating devices.

The fire alarm design will also specify whether the particular fire alarm system will use transponders, networked appliance controllers or other ways of locating audio amplifiers, visual signal power supplies and, more. The design may also specify whether to have toggle type switches to enable individual zone paging or not and, will also specify the means of monitoring the area or stair well pressurization fans. The fire alarm design can be simple for simple fire alarm systems or be complicated for high-end usage.
