NOTES:
• Power consumption for the heater is based on model: 70 VA for the IE model and 72 VA for the
IEE model.
• Use a 24 VAC transformer with a minimum of 100 VA per dome
• If you are operating the camera using 24 VAC and you are wiring more than one camera to the same
transformer, connect one side of the transformer to the red wire (24 VAC +) and connect the other
side of the transformer to the black wire (24 VAC –). Failure to connect all modules identically might
introduce video noise for some installations.
4. Connect the wiring for the alarms and relays.
5. Connect the 24 VAC power wires to operate the heater and blower inside the dome.
