    Study Notes

    Operation of EVAC Systems

    • The Incident Commander must ensure that voice communication equipment is used to notify building occupants of the current situation, direct them on actions to take, provide regular updates, and provide internal communications for crews if necessary.
    • The Lobby Control Officer or Designate is responsible for operating the EVAC system.
    • General broadcast messages can be announced by activating the "ALL CALL" button or switch, which illuminates a series of monitoring lights indicating the areas to be transmitted to.
    • Pressing the microphone "Push To Talk" (PTT) switch activates the building paging system, and may initiate a preannouncement tone of approximately 3 seconds.
    • The alarm system remains silent while the PTT is depressed, and announcements can be terminated by releasing the PTT switch.
    • Canceling the "ALL CALL" and returning communications to default (OFF) can be done by pressing the "ALL CALL" button again.

    EVAC Considerations

    • The EVAC system should be used as an integral component of occupant and fire crew communications.
    • Announcements to building occupants should convey current information about building conditions, provide directions whether to stay or evacuate, advise on evacuation procedures, and convey any other pertinent information.
    • General broadcast or zone announcements should be made at regular intervals to maintain an effective flow of information, even if conditions are unchanged.
    • Two-way communications must provide telephone handsets or jacks in each floor area, near the exit stair shafts.

    Fire Alarm and EVAC Functions

    • Announcements made on the EVAC system should indicate building conditions and evacuation strategies, such as the identification of attack and evacuation stairwells.
    • The annunciator panel may supply information on the location of the original alarm, the type of sensor that initiated the alarm, the location and type of sensor initiating subsequent alarms, and the status of fans, blowers, fire doors, and elevators.
    • Building Control systems adjacent to the EVAC system may incorporate the ability to manually control functions such as evacuation of specific zones or floors, release of automatic door closures, fan control for smoke containment and exhaust, and control of fire and smoke dampers.
