Subsequent alarms shall be presented in the order in which they occur Smoke doors throughout the building in alarm shall close automatically Malfunction of any system initiating device, or a wiring fault, shall establish trouble. Trouble conditions shall be annunciated as follows: A coded signal will be initiated and transmitted to the local Fire Department An alarm status message shall be displayed at the addressable fire alarm control panel serving the area of alarm using a liquid crystal display. Subsequent alarms shall be presented in the order in which they occur The appropriate LED s on the graphic remote annunciator panel shall illuminate Derangement of any supervised sprinkler control valve shall indicate a supervisory condition, which shall be annunciated in similar fashion to trouble, but distinctly identified Elevator capture and return shall be initiated only whenever any of the smoke detectors located in the elevator lobby are activated. The smoke detectors and associated circuits shall be supervised by the fire alarm control panel. Activation of any of these detectors shall establish an alarm condition annunciated at the fire alarm control panel and shall activate the building evacuation alarm. RTKL /10/
