Output interfaces

Description

Three Form C (5A @ 30V) relay output interfaces. Each output connection can be configured

as either Normally Closed (NC) or Normally Open (NO).

• C & NO connection: The relay is normally open. The circuit is closed when triggered.

• C & NC connection: The relay is normally closed. The circuit is opened when triggered.

Notes:

• Install surge protection between the output device and the Cisco PAM module. See the

Cisco Physical Access Gateway User Guide

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

• All Generic Output devices installed in Cisco PAM systems prior to Release 1.1.0 were

connected to the Gateway, Reader, or Output modules with the wiring reversed. If

upgrading to Cisco PAM Release 1.1.0 or later from an earlier release, disconnect all

Generic Output devices and do the following:

Connect Normally Open devices to the N.O. and C connectors on the Gateway,

–

Reader, or Output module.

Connect Normally Closed devices to the N.C. and C connectors on the Gateway,

–

Reader, or Output module.

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).

Tamper input: an unsupervised input that raises a "tamper" 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).
