Positive Input Connections—Positive connection to an Input device.

Ground Input Connections—Ground connection to an Input device.

TM—Tamper input: an unsupervised input that raises a “tamper” alarm when the circuit is open. Can be configured as a general input device using the Cisco Physical Access Manager. An unsupervised input indicates only normal or alarm. The corresponding LED is red when circuit is open (when no input is connected).

PF—Power fail input: an unsupervised input that raises a “power fail” alarm when the circuit is open. Can be configured as an additional unsupervised port. An unsupervised input indicates only normal or alarm. The corresponding LED is red when circuit is open (when no input is connected).

Step 5 Connect output devices to the Gateway (Figure 2-8). Each of the three Form C (5A @ 30V) relay output connections can be configured as either Normally Closed (NC) or Normally Open (NO).

a.Insert three-pin connector plugs into the output ports.

b.Connect the wires from the output devices.

–Common (C) is always used, and either NC or NO is used to complete the connection.

–If the relay is normally open, use the C & NO connections. The circuit is closed when triggered.

–If the relay is normally closed, use the C & NC connections. The circuit is opened when triggered.
