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.
