The
4020/4100/4120
versions of the CCDACT have the following power
requirements.
•
Voltage
-
24VDC Power Supply: 2V max. ripple, 24VDC nominal
•
Current
-
Standby mode:
35 mA maximum from the 24V supply
-
Report mode:
50 mA maximum from the 24V supply
-
Programming mode:
50 mA maximum from the 24V supply
•
Ground Isolation
-
DC resistance between logic 0 and earth ground must exceed
1 Megohm.
The CCDACT has the following environmental limitations.
•
Temperature: 32
°
to 120
°
F (0
°
to 49
°
C)
•
Humidity:
UL = Up to 85% relative humidity at 86
°
F (30
°
C)
FM = Up to 90% relative humidity at 100
°
F (38

C)
The CCDACT has the following discrete inputs:
•
Alarm
•
Priority 2 Alarm (Not included on 4004/4005 models)
•
Supervisory
•
Trouble
•
AC Failure
Note
: An
active signal at any of these inputs triggers an appropriate
"condition" report to the central station; a subsequent inactive signal
triggers an appropriate "restore" report to the Central Station.
