Connecting contacts

The N-111 has a port for contact input (alarms) and contact output (aux). This port is a
five pin header with a supplied plug with screw terminals.  Customer connections to the
contact port are made by securing stripped wire ends into the screw terminals.

Note:  All connections to the screw terminals should be made with the terminal plug
removed from the unit, and with power disconnected from any customer equipment
being connected to the terminals.

Connecting an alarm input

The contact block has two terminals which are used as an alarm/contact input.  Viewing
the rear of the N-111, these two terminals are the two on the left side of the contact
block. These terminals are intended to be connected to customer equipment which will
make or break a connection between the two terminals, such as a door open switch or
motion detector contact output.  It can be designated through the configuration web page
if an alarm condition will correspond to the connection being made or the connection
being broken.

To connect an alarm source such as a door switch or motion detector to the N-111, use
two wires, 16-28 AWG in size.  Strip about ¼” of the insulation from the end of the wires
before inserting them into the terminal block.  Tighten the terminal screws to secure the
wires in the terminal block.

Alarm Input Connection

Note:  the electrical connection to the alarm inputs are to be connected only to isolated
contact closure devices, and must not be directly connected to any external power or
ground source.  Directly connecting either terminal of the alarm input to any voltage
source or external ground may damage the N-111.

Connecting a supervised contact

In supervised contact mode a 1K resistor is connected in series with the contact closure.
This resistor should be located at or close to the contact device, so that short circuits
across the contact lines will be detected. A valid contact closure will be registered only
when the resistance across the contact input lines is measured to be exactly 1K.
