SEQUENCE OF OPERATION (MAU-1�
A. MAU-1 SHALL RUN CONiINUOUSLY. THE OUTSIDE AIR DAMPER SHA�� BE SET AT 400 CiTA
PRESENT/800 CFM FUTURE. THE OUTSIDE AIR AND RETURN AIR SHALL MIX AND BE FILiERED
7NROUGH ANGLED FlI.TER SECTION.
B. A DISCHARGE TEMPERANRE SENSOR SHALL CYCLE THE CONDENSING UNIT COMPRESSOR TO
MAINTAIN 55'F DISCHARGE AIR TEMPERANRE.
G DUCT HEATER EH-1 SHALL BE ENERGRED TO MAINTAIN A DISCHARGE AIR TEMPERANRE SET
POINT OF SSF (ADJ.).
D. DUCT HEATER EH-2 SHALL BE ENERGIZED FROM ITS iHERMOSTAT TO MAINTAIN A SET POINT OF
75F (ADJ.).
E. UPON FAILURE OF EITHER DUCT HEAiER AND/OR THE CONDENSWG UNIT NhIERE
TEMPERATURES CANNOT BE MET iHE FAN SHALI BE DE-ENERGI2ED AND THE O.A DAMPER
CLOSED.
f. UPON DETECTION OF SMOKE BY THE FIRE ALARM SYSTEM (FE-25) THE FIRE/SMOKE DAMPER AT
DATA ROOM 108 SHALL BE CLOSED AND THE UNIT DE-ENERGIZED. ALL CONDUIT AND WIRING
FROM DAMPERS AND STARTER TO ALARM CONTROL PANEL, SHALL BE FURNISHED BY M.C.
SEQUENCE OF OPERATION (DATA ROOM)
A. THE SEVEN (7) AIR CONDITIONING UNITS WiLL BE PROV�DED WIiH ONBOARD MICROPROCESSOR CONTROLS
(iCOM CONTROLLER) EACH SET TO MAINTAIN A ROOM iEMPERATURE SET POINT OF 72' FAHRENHEIT (F)
(ADJUSTABLEj. EACH AIR CONDITIONING UNIT SHALL BE EQUIPPED WITH TWO (2) INDEPENDENT
COMPRESSORS, CONNECTED TO AN AIR COOLED CONDENSER IN A DUAL CIRCUIT PIPING ARRANGEMENT.
WHEN THE UNIT THERMOSTAT SENSES A NEED 'i0 HEAT OR COOL, IT SHALL ENERGIZE THE ASSOCIATED
SYSTEM COMPONENTS THRU MICROPROCESSOR CONTROL. IN ORDER TO MAINTAM THE SPACE SET POINT
TEMPERANRE.
UNDER NORMAL CONDITIONS, SIX UNITS SHALL "RUN" WHILE THE OTHER IS SEQUENCED TO THE
"STANDBY' POSITION. A CHA4GEOVER/SEQUENCER SHALL ROTATE THE UNITS EVERY THREE (3) DAYS
(ADJUSTABLE) UNLESS A UNIT IS SEQUENCED TO "START° AND FAILS. IF FAILURE OCCURS FOR ANY
UNIT, AN A�ARM MESSAGE SHPLL BE SENT TO THE iERMINAL PANEL AND THE FAILED UNIT WILL REMAIN
OFF-LINE.
ALL CONTROL CONDUIT AND CAT-5 NIRING fROM iHE CRAC UNITS TO THE TERMINAL PANEL SHALL BE
PROVIDED BY E.C.
ALL CONTROL CONDUIi AND CONTROI WIRING FROM CRAC UNITS TO CONDENSERS SHALL BE PRONDED
BY M.C.
B. FIRE ALARM- THE MECHANICAL CONTRACTOR SHAI.I. BE RESPONSIBLE FOR PROVIDING EQUIPMENT
START/STOP CONiROL CONDUIT AND W1RWG FROM THE FIRE ALARM (FE-25) PANEL, TO "STOP" ALL
AIR CON�ITIONMG DURING A FIRE SUPPRESSION ENGAGEMENT FOR iHE SPACE.
EACH UNITINCORPORATES A FACTORY PROVIDED SMOKE DETECTOR. UPON DETECTION OF SMOKE THE
DETECTOR SHALL SHUT �OWN THE UNIT AND AlL OPERATIONAL CAPABIUTIES.
SEQUEN�cEACOF OPERATION (ELECTRIC ROOM)
A. THE CONTROLS OF TNE CRAC UNITS SHALL BE SET TO MAINTAIN A ROOM TEMPERATURE SET
POINT OF 72' FAHRENHEiT (F) (ADJUSTABLE).
UNITS SHALI OPERATE IN A LEAD/lAG FASHION. A CHANGEOVER/SE�UENCER SHALL ROiATE 7HE
UNITS EVERY SEVEN (7) DAYS (ADJUSTABLE) UNLESS A UNIT IS SEOUENCED TO "STARi AND
FAILS. IF FAILURE OCCURS FOR EITHER UNIT, AN ALARM MESSAGE SHALL BE SENT TO THE
TERMINAL PANEL AND THE FAILED UNIT NhLL REMAIN OFF-LINE.
NORMAI OPERATION: ONE UNIT OPERATES TO MAINTAIN SPACE TEMPERANRE. IF THE UNIT
FAILS, IT'S ISOLATION DAMPER SHAIL CLOSE AND iNE SECOND UNIT'S ISOLATION DAMPER SHALL
OPEN AND THE SECOND UNIT SHALL ENERGIZE. IF THE SPACE TEMPERANRE RISES 3' F(ADJ.)
ABOVE SETPOINi, THE LEAD UNIT SHALL DE-EMERGIZE, IYS ISOlATION DAMPER SHALL CLOSE, AND
THE SECOND UNIT'S ISOLATION DAMPER SHALL OPEN AND THE SECOND UNIT SHALL ENERGIZE.
IF FAILURE OCCURS FOR ANY UNIT OR TEMPERANRE RISES 3' F(ADJ.) ABOVE SETPOINT, AN
ALARM MESSAGE SHALL BE SENT TO THE TERMINA� PANEL. THE FAILED UNIT WILL REMAIN
OFF-LINE.
ALL CONIROL CONDUIT ANO CAT-5 `MRING FROM THE CRAC UNITS TO THE TERMINAL PANEL
SHALL BE PROVIDED BY E.C.
ALL CONIROL CONDUIT AND CONTROL WIRING FROM CRAC UNITS TO CONDENSERS SHALL BE
PROVIDED BY M.C.
8. EACH UNIT INCORPORAiES A FACTORY PROVIDED SMOKE DETECTOR. UPON DETECTION OF SMOKE
THE DETECTOR SHALI SHUT DOWN THE UNIT AND AlL OPERATIONAL CAPABILITIES.
