Dry Contact to Energy Management System
Multiple inputs from an EMS system may be connected with
a single common as shown. Normally programmed as
MAINTAINED inputs.

A powered Digilink has a 24 volt output to power most occupan-
cy sensors, 850 ma is available. Only use occupancy sensors
that have “dry contact outputs.” these are usually designated as
-RP or some other option to indicate that an additional relay has
been added for building automation purposes.
Connect occupancy sensors to the the Scene Input indicated on
the paperwork that came with the system.
A typical Occupancy sensor is a Mytech Light Owl sensor made
by Hubbell Building Automation. Here is their diagram:
Note that we do not need to connect 4 wires to this sensor since the Blue
White wire may be connected to the Ground or Black wire for the control
power.

The Watt Stopper has very similar wiring to the Hub-
bell. The DT 200 has the auxiliary contacts built in
without being an option.

Novitas is one of the few sensors on the market that
has an output that “pulls low” (using a transistor) and
can be used with the GR 2404-DIM without a separate
relay option.
