Wire Alarm Input Connector

NOTE: Figure 6-21shows the alarm input connector wiring to a typical alarm interface circuit. The facility alarm input to the Access Navigator should provide normally open contacts. The Access Navigator will energize these wires so that a contact closure will produce a minor alarm indication and minor alarm message.
