Installing the NC-2000 Patient Unit
3.3 Inputs
Terminal CN6 has four wet contact inputs for call points (with ground returns) on a screw-type
terminal block. Inputs should be grounded to their respective ground return through a contact
to indicate activity. See Figure 12 for the locations of the four inputs and their ground returns.
Figure 12 Input connections on CN6
Note:
Do not overtighten the screw terminals.
Notes:
The following points regarding the inputs apply:
•
Inputs connected to CN6 should be of the normally open type.
•
For supervision, connect a 10K ohm resistor across the input.
•
Circuits connected to the inputs
must
be limited to a voltage of less
than 30V and power less than 100VA in order to comply with
UL 1069 and UL 2560.
