1 PART 0 DESIGN STANDARDS 0.01 USE OF THIS STANDARD A. Due to the extent of detail provided in this standard, the A/E may choose to edit this standard and incorporate portions of this standard in the construction documents. To obtain an electronic copy of this standard in Microsoft Word format, contact the DPS Project Manager GENERAL DESIGN REQUIREMENTS A. New facilities and facilities to be substantially renovated must include a fire alarm system. 1. Exceptions include very small single story buildings, sheds, and temporary facilities where coderequired systems are not mandatory and the occupancy does not warrant a system. B. Renovations affecting existing systems shall be handled on a case-by-case basis with direct input from DPS. C. This standard covers new fire alarm systems. D. Inspections and testing by others do not relieve the A/E of contract responsibilities. Conduct necessary observations and inspections including, but not limited to, rough-in observations and punch list preparation and backchecking. Provide reports DESIGN CRITERIA A. General: 1. The following guide spec is to provide the A/E with the information needed to specify and design fire alarm systems for DPS. This guide spec provides the types of systems and detectors to be used, shop drawing requirements, annunciator requirements, sequence of operations, A/Eing drawing requirements, and the A/E's duties. 2. The A/E should avoid specifying proprietary features of specific manufacturers. B. Existing Systems: 1. On projects where existing systems are revised or expanded, the A/E shall meet with the Contractor and the DPS Project Manager to verify the operating condition of the existing system before the Contractor begins work on the system (i.e., is the existing system functioning properly, etc.). The A/E shall include this requirement in the project specifications. 2. Where a new system is being installed to replace an existing system, the existing fire alarm systems shall remain fully operational until the new work is completed and the entire new system is functional and accepted by the Fire Department. 3. Where a new system is being installed to replace an existing system, the A/E shall require the Contractor to field verify and show the locations of sensors. C. Circuits and Raceway: 1. Fire alarm system wire and cable shall be located in concealed metal conduit regardless of code exceptions. Location and routing shall take advantage of areas easily accessed by DPS Maintenance personnel (hallways/corridors) and shall consider future modification and/or extension wherever practical. 2. Raceway fill shall be less than 40% per NEC. Calculations proving this will need to be submitted for review. Raceway capacity between control panels and terminal cabinets shall be sufficiently sized to accept additional circuits in the future. A/Es are encouraged to show a minimum size that would accommodate future work. 3. Circuits shall be laid out to serve a specific geographical area (zone) per floor. 4. Field located transponders and power supply panels may be used. Good access must be provided for testing and maintenance requirements Page 1 of 23

4 is silenced or reset. The visual alarms shall continue to flash until the system is reset. The silencing of audible signals shall be a separate function from reset. b) Activation of any sprinkler or standpipe valve tamper switch shall activate the system supervisory alarm and illuminate the supervisory LED on the control panel. c) In the event of an open or ground in a circuit or an off-normal condition, a trouble alarm shall sound and the trouble LED on the control panel shall be illuminated. Acknowledgement of the trouble or operation of the trouble silence switch shall cause the audible alarm to silence. The trouble condition shall remain on the system until the trouble is corrected. Once the trouble is corrected, the trouble alarm shall self-restore. d) Include any modifications to the security system to monitor these points. Trouble and supervisory alarms are not to be transmitted to the City Fire Alarm Headquarters. 10. Automatically transmit a coded signal to the City Fire Alarm Headquarters through a G. H. Harlow radio transmitter. It shall be possible to disable the transmitter for testing and maintenance purposes. Disabling the signal to the City shall cause a trouble alarm to sound. Silencing the trouble alarm shall leave a trouble light until the system is restored to on-line status. The system shall transmit to the radio transmitter those alarms required by the AHJ. The radio transmitter will then send the alarms to the Fire Alarm Headquarters. For schools with a swimming pool, an additional "drowning alarm," activated by a separate manual box in the pool area, shall be transmitted. The drowning alarm sounds a different sound (not temporal pattern) in the pool area only, not as a general alarm throughout the building. The pull station will be yellow and be labeled as Drown Alarm. Special systems such as kitchen hoods, etc. shall be transmitted as separate alarms. Use existing Bronco panel for renovations to existing systems. The interface panel and radio transmitter are limited to seven (7) zones. If more than seven zones are required, additional interface panels and transmitters will be required. 11.
