FIRE PROTECTION:

Fire Alarm Panels: Must use Monaco Enterprises – BTXF Fire Communicators and Controllers. There must be enough zones to be able to clearly identify what triggered the alarm (sprinkler, pull station, heat/smoke, trouble, etc.) as well as identify where specifically in the building that particular alarm was set off. Coordination with the Luke AFB fire department is mandatory throughout the design process and prior to purchasing any fire alarm equipment.

Elevators: Elevator emergency call buttons must be able to accommodate two-way conversation. It is required for Luke AFB emergency responders to be able to talk with the person in the elevator.
