Cisco Alarm Relay Interface Card - Expansion module - refurbished - plug-in module
The Alarm Relay Interface (ARI) card contains the alarm relays and their associated relay drivers. Alarm outputs are dry contact closures or opening contacts from Form C relays. The user must supply the voltage source to be switched by the IGX. A female DB37 connector resides on the faceplate for connection to the customer's office alarm or alarm-reporting system.
