A. EQUIPMENT ROOM :
AIR CONDITIONING UNIT ACU-1 OR ACU-2 OPERATE ON DEMAND FROM DDC CONTROL
PANEL AFTER RECEIVING TEMPERATURE SIGNAL FROM ROOM TEMPERATURE SENSOR TS-1.
THE DDC CONTROLLER PROVIDES THE FOLLOWING: INDOOR FAN ON ACU-1 OPERATE
CONTINUOUSLY. ACU-1 PROVIDES AUTOMATIC SEQUENCE OF TWO COMPRESSORS, TO
MAINTAIN INDOOR TEMPERATURE OF 78 F. WHENEVER INDOOR ROOM TEMPERATURE RISES
TO 85 F, ACU-2 ENERGIZES AND ACU-1 DE-ENERGIZES.
WHENEVER SPACE TEMPERATURE DROPS BELOW 65 F, UNIT HEATERS (EUH-2 AND 3) ENERGIZES
TO MAINTAIN 65 F IN THE SPACE. ACU-1 OR ACU-2 DE-ENERGIZES AND CORRESPONDING
DAMPER IN SUPPLY, RETURN, OUTDOOR AIR DUCT AND RELIEF HOOD CLOSED. REVERSE OCCURS
WHEN TEMPERATURE RISES ABOVE 65 F.
UNIT HEATER (EUH-4) ENERGIZES WHENEVER SPACE TEMPERATURE IN TELCO ROOM DROPS
BELOW 40 F. THE REVERSE OCCURS WHEN TEMPERATURE RISES ABOVE 40 F. SMOKE DETECTOR
IN RETURN AIR DUCT OF ACU-1 OR ACU-2 DE-ENERGIZES RESPECTIVE ACU'S AND ALARM
SIGNAL SENTS TO DDC IF SMOKE OR FIRE IS DETECTED.
A PROGRAM IS PROVIDED TO ALTERNATE AUTOMATICALLY THE ACU-1 TO ACU-2 UNIT FOR
EVERY 500 HOURS OF DISTRIBUTED USAGE OF UNIT.
ACU INTERLOCKS:
A PROGRAM IS PROVIDED TO INTERLOCK ACU-1 AND ACU-2 SO THAT ONLY ONE OF THE UNITS
CAN OPERATE AT A TIME.
A MINIMUM OF FOLLOWING POINTS ARE PROVIDED IN DDCP PANEL:
a) START/STOP STATUS AND ALARM OF EACH ACU'S SYSTEM.
b) SPACE TEMPERATURE INDICATION WITH HIGH ALARM OF 85 F AND LOW ALARM OF 60 F.
c) TOTAL RUN TIME OF EACH UNIT
d) ALARMS (AUX CONTACTS)
1. DIRTY FILTER
2. COMPRESSOR FAILURE
3. FAN FAILURE
B. ENGINE/GENERATOR ROOM:
WHEN ENGINE IS IN OFF POSITION AND INDOOR TEMPERATURE RISES TO AND ABOVE
90 F(TS-2), DAMPER D-1 AND D-2 OPENS.
UPON FURTHER RISE IN TEMPERATURE TO 95 F EXHAUST FAN (EF-1) OPERATES.
WHEN INDOOR TEMPERATURE FALLS TO BELOW 90 F EXHAUST FAN(EF-1) DE-ENERGIZES.
DAMPER D-1 AND D-2 CLOSES.
INTAKE DAMPER D-2 AND EXHAUST DAMPER D-1 INTERLOCKS WITH EXHAUST FAN
EF-1 TO OPEN FULLY WHENEVER THE EXHAUST FAN IS IN OPERATION.
PROVIDE 10 SECOND TIME DELAY FOR FAN OPERATION.
ELECTRIC UNIT HEATER: UNIT HEATER EUH-1 ACTIVATES BY BUILT-IN
THERMOSTAT TO MAINTAIN INDOOR TEMPERATURE OF 40 F.
PROVIDE A MINIMUM OF FOLLOWING POINTS:
a) STATUS OF DAMPER POSITION
b) START/STOP STATUS OF EXHAUST FAN-1
c) ALARMS
1. FUEL LEVEL AND LEAK DETECTION
C. GENERAL:
ALL TEMPERATURE SENSORS LOCATED AT HEIGHT OF 5 FEET ABOVE FLOOR LEVEL.
D. INTRUSION ALARM:
A MICROSWITCH ON DDCP PANEL TO MONITOR UNAUTHORIZED OPENING OF PANEL.
MICROSWITCH SENDS ALARM TO THE DDCP.
WHEN GENERATOR IS STARTED, DAMPER D-1 AND D-2 OPEN, AND EXHAUST FAN EF-1 STARTS
AND OPERATES.
