Should an alarm condition continue to exist, the system will remain in an abnormal state. System control relays shall not reset. The panel audible signal and the Alarm LED shall be on. The display will indicate the total number of alarms and troubles present in the system along with a prompting to review the points. These points will not require acknowledgment if they were previously acknowledged. G. History Logging 1. In order to recreate a sequence of events in a fire or trouble investigation, the control panel shall store system abnormal conditions in three separate logs. Alarm activities shall be stored in an Alarm Log, sprinkler supervisory (tamper switch) activation in a Supervisory Log, and trouble events in a Trouble Log. The time and date of each occurrence must be included with each entry. These events shall be stored in a battery protected random access memory (RAM). In order to prevent re-occurring trouble and/or sprinkler supervisory conditions from overwriting other information, it is mandatory that each type of event be stored separately. Systems that are not equipped with separate logs, as described, shall include a UL listed fire alarm printer with battery back-up to record system activity including time and date of each occurrence. H. Walk Test with History Logging 1. The system shall be capable of being silently tested by one person. While in testing mode, the alarm activation of an initiating device shall be silently logged as an alarm condition in the historical data file. The panel shall automatically reset itself after logging of the alarm. 2. The momentary disconnection of an initiating or notification appliance circuit shall be silently logged as a trouble condition in the historical data file. The panel shall automatically reset itself after logging of the trouble condition. 3. Should the walk test feature be on for an inappropriate [programmable] amount of time, it shall revert to the normal mode automatically. 4. The control panel shall be capable of supporting up to eight (8) separate testing groups whereby one group of points may be in a testing mode and the other (non-testing) groups may be active and operate as programmed per normal system operation. After testing is considered complete, testing data may be retrieved from the system in chronological order to ensure proper device/circuit activation. I. System Trouble Reminder 1. Should a trouble condition be present within the system and the audible trouble signal silenced, the trouble signal shall resound at preprogrammed time intervals to act as a reminder that the fire alarm system is not 100% operational. Both the time interval and the trouble reminder signal shall be programmable to suit the owner's application. J. Smoke Sensor Operation 1. The smoke sensors shall automatically meet NFPA sensitivity testing requirements. 28 31 11-3 (45307035)

a. The control panel shall be listed as a calibrated sensitivity testing instrument that will automatically meet NFPA 72E Sensitivity Testing Requirements. The requirement to test the sensitivity of each detector within one year of installation and every alternate year thereafter as described in NFPA 72E shall not need to be performed manually. 2. The smoke sensors shall be smoke density measuring devices having no self contained alarm set-point. The alarm decision for each sensor shall be determined by the control panel. The control panel shall determine the condition of each sensor by comparing the sensor value to stored values. 3. The control panel shall maintain a moving average of the sensors smoke chamber value. The system shall automatically maintain a constant smoke obscuration sensitivity for each sensor and compensate for environmental factors such as dust accumulation. 4. The system shall automatically indicate when an individual sensor needs cleaning. When a sensor's average value reaches a predetermined value, a "Dirty Sensor" trouble condition shall be audibly and visually indicated at the control panel for the individual sensor. Additionally, the LED on the sensor base shall glow steady giving a visual indication at the sensor location. a. The smoke sensor shall not be operating at an increased sensitivity level due to the dust/dirt contamination. It shall continue to operate at the pre-set sensitivity level. 5. It shall be possible to program the control panel to automatically change the sensitivity settings of each sensor based on time-ofday and day-of-week. (For example, to be more sensitive during unoccupied times and less sensitive during occupied periods.) 6. The control panel shall have the capability of being programmed for a pre-alarm or two-stage function. This function shall allow a "pre-alarm" indication to occur when, for example, a 3% sensor reaches a threshold of 1.5% smoke obscuration. 7. The control panel shall have the capability to automatically log smoke obscuration levels at each individual sensor location, under normal conditions, for a 30-day period. The system shall then be adjusted to set individual sensor sensitivity levels slightly above the maximum obscuration recorded at each location. This will insure the earliest possible detection to smoke while eliminating false alarms caused by normal conditions in the area of each sensor. K. Network Communication Operation 1. Each node (building control panel, graphic command center) shall communicate to the next in a token ring configuration at 57.6 Kbaud via the campus fiber network. (The new FACP will be a new node on the existing campus network. Coordinate copper and /or fiber network interfaces as required.) 2. In the event that the path to the next node on the ring has experienced a communications failure, the node with possession of the token shall transmit it back in the direction from which it came to attempt to reach the next node by going around the ring in the opposite direction. At the same time, the status of the noncommunicating node shall be added into the token content. 3. The communication method shall be NFPA 72 style 7. Full communication between all nodes shall be maintained if an open occurs on the network communication lines. 4. Network time synchronization with seconds resolution accuracy shall be provided by designating one node as the network timekeeper. This node shall notify the network of authorized time and date changes. During periods without any time or date 28 31 11-4 (45307035)

changes, the network timekeeper shall maintain network time synchronization by network communication once every 24 hours. In the event that the network timekeeper is unable to communicate the correct time, each node shall maintain its own local time and date reference using an internal, crystal controlled oscillator. 1.5 ALARM SEQUENCE A. The system alarm operation subsequent to the alarm activation of any manual station or automatic detection device is to be as follows: 1. All audible alarm notification appliances shall sound a temporal code pattern (.5 sec. on,.5 sec. off,.5 sec. on,.5 sec. off,.5 sec. on, 2.5 sec. off, then repeat) until silenced by the alarm silence switch at the control panel, remote annunciator or at the existing Campus Network Control Panel/Annunciator. 2. All visible alarm notification appliances [Xenon Strobes] shall display a continuous pattern until the system is reset. 3. All doors normally held open by door control devices shall release. 4. All egress doors normally locked by electric locking devices shall release. 5. The individual alarm device information shall be displayed on the local FACP and associated annunciators. This information shall also be transmitted via fiber-optic network communication across the existing fire alarm network to annunciate appropriately at other network panel locations. 6. The alarm is to be recorded with the time and date in the local control panel s alarm log as well as being recorded on other annuciated network panels. B. The alarm activation of any elevator lobby smoke detector shall, in addition to the operations listed above, send a signal to the elevator controller for a Fire Hat signal and recall the elevators according to the following sequence: 1. If the alarmed detector is on any floor other than the main level of egress, the elevator cabs shall be recalled to the main level of egress. 2. If the alarmed detector is on the main egress level, the elevator cabs shall be recalled to the predetermined alternate recall level as determined by the local authority having jurisdiction. C. Activation of any smoke detector in an elevator shaft or machine room shall send a signal to the elevator controller for a flashing Fire Hat signal. D. The activation of any elevator related heat detector shall, in addition to the operations listed above, activate the associated elevator shunt-trip breaker to remove power from the elevator. 1.6 NOTIFICATION APPLIANCE OPERATION A. The system shall provide for the synchronization and control of the audible and visible notification appliances on a common 2-wire circuit.
