Fire Alarm System

Description and Purpose

Fire is one of the most costly causes of damage and loss of life in a facility. Fire alarm systems supervise the facility for smoke, heat, fire sprinkler water flow and its PIV, and the activation of a manual pull station. In addition, the facility may require supervision of a Knox Box, HVAC damper control and elevator recall capabilities.

Solving Intrusion Issues

There are a number of critical issues that are solved with fire alarm system.
When designing a fire alarm system, the most important issue is fast detection, notification, and evacuation.

Locate Smoke Detectors in hallways, business offices, break rooms, and restrooms.

Locate Heat Detectors in dusty areas like warehouses, attics, basements, or in shop environments.

Locate Manual Pull Stations next to exit doors and emergency doors.

Monitor the Fire Suppression Sprinkler System using Fire Sprinkler Water Flow sensors. Supervise all supply valves to ensure that they remain open and in service.

Moving the Elevator to the proper floor and disabling it requires Elevator Recall capabilities.

The HVAC system normally distributes air throughout a facility. Damper Control causes the airflow to be suspended from areas where smoke is being drawn into the HVAC system to minimize the spread of smoke within the facility.
