Input and Output Connections

20 AC-215IP Hardware Installation Manual

4. Input and Output Connections

This chapter describes the AC-215IP access control panel's input and output

connections.

4.1 Input Types

There are four input types – Normally Open, Normally Closed, Normally Open

Supervised 1 or 2 resistors, and Normally Closed Supervised 1 or 2 resistors.

Inputs IN1, IN1A, IN2 and IN2A may be configured individually as either

supervised or non-supervised inputs. Configure each input separately via the

AxTraxNG™ system.

Non-supervised inputs have two states:

 Normal State

 Abnormal State

Supervised inputs have three states:

 Normal State

 Abnormal State

 Trouble State

The Trouble state is caused by either tampering with the input circuit or by

faulty hardware installation. Once configured as supervised input, add a

resistor of 2.2 K, of 8.2 K, or both on the input circuit. See the figures in the

following subsections.

4.1.1 Normally Open Input Connection:

Normally Open Input has 2 states:

 Switch Open – Normal State:

Loop resistance = Infinite (open circuit)

 Switch Closed – Abnormal State:

Loop resistance = 0 (short circuit)
