External Alarms Specification; Idu-C Alarms - Radwin WinLink 1000 Series User Manual

External Alarms Specification

Each of the three products, IDU-E-AL, IDU-C and PoE-8 have a dry contact
alarm relay through a standard DB9 or DB25 pin female connector. There
are two alarm types – input and output.
Input alarms
The input alarms are raised by events from external equipment, such as
a fire warning, door open or air conditioner failure. They are user
defined.
Output alarms
Output alarms are generated through dry contact relays to indicate vari-
ous system events such as sync loss or disconnection. An alarm is raised
if at least one of the conditions in one of the tables below, is met.
