A business needs to be able to detect danger as the most critical of all fire prevention measures. Wardens need to be able to notify and communicate during an evacuation, and these are critical for the life safety of occupants, customers and others.
Alarm systems are complex and used in large buildings. These allow for a comprehensive and controlled evacuation of a building in the event of an emergency. Based on the class of the building and its intended use, there are a number of types of warning systems available to achieve these objectives of warning. Complex alarm systems come in the form of Emergency Warning Intercommunication Systems (EWIS), or a less complicated Occupant Warning Systems (OCS, also called Emergency Warning System (EWS). The latter two do not have the intercommunication (PA) and red phone) capabilities of the EWIS.
Usually, these alarms will automatically pick up a problem such as a drop in water pressure at the pump (due to a sprinkler gone off) and will sound a warning tone. Particularly, most EWIS, EWS and OWS systems are set up to sound two tones (Beep, beep, Whoop, whoop), and can even have a voice with a message to evacuate. When a fire alarm panel is in place, it will pick up the problem and sound the alarm. Some fire panels will even call the emergency Services. The emergency fire team called the Emergency Control Organization (ECO) should be able to hear and understand what the different tones mean, and immediately take action toward the emergency, based on their training.
A chief fire warden is able to take control of the EWIS system using the internal phone to speak to the floor wardens to ensure all levels have been evacuated and the inbuilt PA (public address) system allows the chief warden to relay direct messages over the system.
