Powering Up
After making all connections and installing the ISK4 in the wall box, plug the camera power
supply into an AC receptacle and power up the ComPoint system. Also power up the video
display being used to receive the camera signal.
Check the camera angle to make sure a person standing at the door is visible. If necessary,
power down the system and readjust the camera angle.
Operation
Press and release the Call button to ring the doorbell. When a person inside replies from a
keypad, you will hear a single beep when they begin the reply and again when they’re done
speaking. You then can answer the reply within 7 seconds by just speaking. After 7 seconds,
you will hear a double beep, after which you can no longer answer the reply.
Note: Pressing and releasing the Call button always rings the doorbell. To answer a reply, just
speak without pressing the Call button.
You will hear a buzz tone from the door station when the person inside activates the door strike
release.
For a more detailed description of door station operation, read the ComPoint system manual.
Speaker Volume Adjustment
Use the potentiometer to adjust the speaker volume. Turn it clockwise to raise the volume or
counterclockwise to lower it. This does not affect the microphone sensitivity.
