Installation, Programming, and Troubleshooting
Note: The ICAD is powered by a 24 Volt DC power source.
There are two cables pre-mounted and connected to the ICAD motor actuator. Never try to
open the ICAD motor because the special moisture seal will be damaged.
The power cable consists of 3 wires:
• Green: (–) common (ground)
• Brown: (+) positive from 4VDC power source
• White: (+) positive from UPS/battery backup (optional)
The control cable consists of 7 wires:
• Yellow: (–) common (ground)
• Gray:
• Blue:
• Pink:
• White: common alarm (digital NPN transistor output when combined with
• Brown: indicates ICM is fully open (digital NPN transistor output when combined
• Green: indicates ICM is fully closed (digital NPN transistor output when combined
Supply voltage is galvanically isolated from input and output wires.
