• Reports the change in state to the CPUn module
The local and remote alarm cutoffs operate independently of each other. This
change in state (on to off, off to on) is also shown in the Audible Alarm Sta-
tus panel of the console Alarm Configuration window.
A CO, remote switch room, or hut contains a number of sensors that monitor
environmental conditions, power availability, moisture, and so on. The 4500
Alarm module has 15 input sensors that monitor the activity or state change
of these external sensors (through relay contact open or close conditions),
and report the status of them to the NOC through trap messages and the
Alarm Module Configuration window. An example of a remote sensor would
be a door sensor that indicates whether the door is open or closed as shown
in Figure 2-5.

Alarm module activates a relay contact closure
(for 30 seconds) and activates remote device,
In situations where a remote sensor input to the 4500 Alarm module indi-
cates a condition that requires external intervention, such as when the tem-
perature in the CO exceeds a predefined limit and supplemental air condi-
tioning is required, the 4500 Alarm module provides four relays that can be
connected to supplemental devices to allow the NOC operator to activate
them by sending activation commands by way of the 4500 Alarm module.
