1. PROVIDE AN ADDRESSABLE FIRE ALARM SYSTEM AS INDICATED ON THE DRAWINGS.

NOTIFICATION SYSTEM MUST BE CAPABLE OF PROVIDING 3 TEMPORAL OR 4 TEMPORAL

EVACUATION SIGNAL DEPENDING ON THE ALARM.

2. COORDINATE ALL REQUIRED SYSTEMS TO THE SATISFACTION OF THE ENGINEER AND

AUTHORITY HAVING JURISDICTION. ANY DEFICIENCIES, INCONSISTENCIES, OR POORLY

COORDINATED INSTALLATIONS MUST BE CORRECTED BY THE CONTRACTOR AT NO

ADDITIONAL COST.

3. THE FIRE ALARM DRAWINGS ARE SCHEMATIC IN NATURE AND SHOW A MINIMAL QUANTITY OF

DEVICES. DETERMINE THE FINAL QUANTITY AND LOCATION OF ALL DEVICES IN ACCORDANCE

WITH THE SPECIFICATIONS, CONTRACT DRAWINGS, AND MANUFACTURER'S WRITTEN

RECOMMENDATIONS TO BE COMPLIANT WITH ALL APPLICABLE CODES AND STANDARDS.

PROVIDE ADDITIONAL DEVICES WHEN REQUIRED FOR A FULLY FUNCTIONING FIRE ALARM

SYSTEM AS REQUIRED BY NFPA 72.

4. SURFACE MOUNT CONDUITS TO WALLS AND CEILINGS THROUGHOUT THE BUILDING. WHERE

A CONDUIT SUPPLIES A DEVICE NOT MOUNTED DIRECTLY ON THE WALL OR CEILING, ROUTE

THE CONDUIT AS A SINGLE PENDENT DROP TO EACH DEVICE FROM THE CEILING SURFACE

ABOVE. DO NOT TRAPEZE CONDUIT ACROSS AN OPEN SPACE.

5. ALL FIRE ALARM JUNCTION BOXES, COVERS AND CONDUITS IN UNFINISHED AREAS ARE TO

BE PROVIDED PRE-FINISHED RED FROM THE FACTORY. PAINT EXPOSED CONDUIT AND

JUNCTION BOXES IN FINISHED AREAS TO MATCH ADJACENT SURFACES WITH JUNCTION

BOXES INSIDE COVER LABELED, "FIRE ALARM", AND WHERE CONDUIT PENETRATES A WALL,

PAINT RED 3/4 INCH BANDS EVERY 20 FT AND BOTH SIDES OF PENETRATIONS.

6. PROVIDE CONDUIT IN ACCORDANCE WITH THE REQUIREMENTS OF THE ELECTRICAL

SPECIFICATIONS, UNLESS OTHERWISE NOTED. SUPPORT CONDUIT IN ACCORDANCE WITH

THE NEC SUCH AS MAXIMUM 10 FT SUPPORT INTERVALS AND 3 FT FROM A TERMINATION.

TENSION ONLY HANGERS ARE NOT PERMITTED SUCH AS BATWINGS. FLEXIBLE CONDUIT IS

ONLY PERMITTED WHEN CONNECTING TO THE FOLLOWING DEVICES AND APPLIANCES:

DEVICES LOCATED ON FIRE SUPPRESSION EQUIPMENT SUCH AS FLOW/PRESSURE

SWITCHES AND TAMPER SWITCHES, DEVICES AND APPLIANCES LOCATED IN REMOVABLE

CEILING TILES, OR WHERE SPECIFICALLY NOTED.

7. PROVIDE CONDUCTOR SIZING NOT LESS THAN 18 AWG FOR SLC. PROVIDE CONDUCTOR

SIZING NOT LESS THAN 16 AWG FOR NAC, AND IDC. CONSISTENTLY COLOR COORDINATE ALL

CONDUCTORS THROUGH THE SYSTEM IN RELATION TO DEVICES THEY FEED SUCH AS SLC -

BLACK/RED, STROBE - YELLOW/BLUE. PROVIDE ADDRESSABLE SLC CIRCUITS WITH SHIELDED

CONDUCTORS, WHERE THE SHIELDING IS GROUNDED AT ONE END WHERE REQUIRED BY

THE MANUFACTURER. PROVIDE ALL CIRCUITS WITH LAVELING AT THE POINT OF

TERMINATION SUCH AS SLC 1, NAC 8, IDC 4.

8. RUN CONDUCTORS FROM DEVICE TO DEVICE WITHOUT SPLICES. WIRE NUTS ARE

PROHIBITED. UTILIZE TERMINAL STRIPS WHERE CONDUCTORS CANNOT BE DIRECTLY

TERMINATED AT THE DEVICE SUCH AS PIGTAILS OFF A HEAT DETECTOR.

9. DO NOT USE FIRE ALARM EQUIPMENT PANELS AS RACEWAY FOR ROUTING POWER WIRING

OR LOW VOLTAGE WIRING. ONLY ROUTE WIRING TERMINATING WITHIN THE PANEL INTO THE

PANEL. PROVIDE 1/4 INCH SEPARATION BETWEEN POWER-LIMITED FIRE ALARM CIRCUITS

AND POWER CIRCUITS.

10. MOUNTING DEVICES IN THE FACU, INCLUDING ANY SUBPANELS SUCH AS NAC AND FAC,

WHICH ARE NOT UL LISTED OR FM APPROVED AS PART OF THE UNIT IS PROHIBITED.

11. PROVIDE SURGE SUPPRESSORS TO PROTECT ALL POWER SUPPLY CIRCUITS TO THE FACU,

INCLUDING ANY SUBPANELS SUCH AS NAC, FAC, AND ALL FIRE ALARM CIRCUITS LEAVING OR

ENTERING THE BUILDING. DEVICES AND APPLIANCES MOUNTED DIRECTLY ON THE EXTERIOR

OF THE BUILDING SUCH AS WALL MOUNTED EXTERIOR HORN STROBES DO NOT REQUIRE

SUPPRESSORS. MOUNT SURGE SUPPRESSORS IN A SEPARATE ENCLOSURE, UNLESS IT IS UL

LISTED OR FM APPROVED AND INSTALLED IN THE CONTROL UNIT BY THE FACTORY.

12. INSTALL FIRE ALARM BATTERIES IN THE ENCLOSURE OF THE DEVICE/UNIT IT SUPPORTS

SUCH AS FACU ENCLOSURE OR IN AN INDEPENDENT DEDICATED ENCLOSURE.

13. EXTERIOR SIGNAGE MUST COMPLY WITH SPECIFICATION 10 14 00.10.

AUDIBLE DESIGN CRITERIA:

VISIBLE DESIGN CRITERIA:

1. PROVIDE AUDIBLE NOTIFICATION APPLIANCES AS INDICATED TO ACCOMPLISH THE FOLLOWING

DESIGN CRITERIA WITH ALL DOORS, FIRE SHUTTERS, AND WINDOWS CLOSED. WHERE THIS

DESIGN CRITERIA IS NOT ACCOMPLISHED DURING ACCEPTANCE TESTING, PROVIDE

ADDITIONAL DEVICES TO MEET THE MINIMUM DESIGN CRITERIA WITHOUT EXCEEDING THE

LIMITATIONS OF THE FACU, OR NAC (INCLUSIVE OF PRESCRIBED SAFETY FACTORS).

2. PROVIDE A QUANTITY OF HORNS IN EACH ROOM/AREA TO ACHIEVE THE REQUIRED SOUND

POWER OUTLINED IN THESE CONTRACT DOCUMENTS.

3. PROVIDE A MINIMUM SOUND POWER OF 70 DBA AND 15 DBA OVER THE AVERAGE AMBIENT

SOUND LEVEL OR 5 DBA ABOVE THE MAXIMUM SOUND LEVEL HAVING A DURATION OF AT LEAST

60 SECONDS, WHICHEVER IS GREATER, AT THE MOST REMOTE LOCATION WITHIN THE

ROOM/AREA MEASURED AT 5 FT AFF. MEASURE THE SOUND POWER OFF THE TEMPORAL

THREE TONE PATTERN.

4. THE FOLLOWING CRITERIA WILL BE USED FOR REVIEW AND APPROVAL OF SHOP DRAWINGS.

A. REDUCE THE SOUND POWER BY 6 DB EACH TIME THE DISTANCE BETWEEN THE

APPLIANCE AND THE LISTENER IS DOUBLED. STARTING DISTANCE IS PER

MANUFACTURER'S DATASHEET, TYPICALLY 10 FT.

B. REDUCE THE SOUND POWER IN ACCORDANCE WITH THE MANUFACTURER'S DATASHEET

FOR SOUND POWER DISTRIBUTION NOT PERPENDICULAR TO THE FACE OF THE

APPLIANCE. REFER TO MANUFACTURER'S TYPICAL SOUND OUTPUT DISTRIBUTION

DIAGRAM.

C. IN LIEU OF THE MANUFACTURER'S PUBLISHED DB LOSS, ASSUME A MINIMUM 15 DB LOSS

THROUGH A STANDARD CLOSED DOOR.

1. PROVIDE VISIBLE NOTIFICATION APPLIANCES TO ACHIEVE THE COVERAGE INDICATED.

2. SPACE STROBES IN ACCORDANCE WITH THE CRITERIA OUTLINED IN NFPA 72, UNLESS

OTHERWISE NOTED.

1. SERVE THE FIRE SUPPRESSION SYSTEM FROM THE EXISTING DOMESTIC

SYSTEM AND PROJECT'S FIRE BOOSTER PUMP SYSTEM. PERFORM A

HYDRANT FLOW TEST, AND INCORPORATE THIS TEST INTO THE

HYDRAULIC CALCULATIONS. HYDRANT FLOW TESTING MUST BE IN

ACCORDANCE WITH NFPA 291, AND THE RESULTS OF THE TESTING MUST

BE SUBMITTED AS INDICATED IN NFPA 291 FIGURE 4.11.2.

FOR INFORMATION ONLY: FLOW TEST 1. REFER TO SHEET FX001 FOR IMAGE

SHOWING LOCATIONS OF GAUGE AND FLOW

HYDRANTS.

DATE 11/21/2019

TIME 1101

STATIC 70 PSI

RESIDUAL 48 PSI
