Configuring Normal Input States for Alarms
I M P O R T A N T
Some controllers allow the normal input states for domes to be specified at the controller. These controllers include VM96, AD matrices with
The normal input state for an alarm is the state that the device maintains when an alarm is not occurring. For example, you have a smoke detector connected to a dome input. Under normal circumstances, the smoke detector should not be detecting smoke. When smoke is detected, the alarm input changes states (from open to closed) and an alarm is issued.
To configure the normal state for the alarm, select Set Alarm States from the
Alarm/Areas/Home/Presets/PZ screen. The following screen appears:
| SET ALARM STATES | |
INPUT NO. |
| NORMAL STATE |
1 |
|
|
| OPEN / CLOSED | |
2 |
| OPEN / CLOSED |
3 |
| OPEN / CLOSED |
4 |
| OPEN / CLOSED |
EXIT
Use this screen to assign open or closed as the normal state for the dome alarm inputs. When an input state changes from normal to abnormal and an internal alarm action is associated with the input, the alarm is triggered. The normal state is used by both internal alarms and controller defined alarms.

When operating on Manchester networks, the dome can be programmed to respond to any of the four available alarm inputs. However, the alarm input states cannot be transmitted to the host controller. If transmitting the alarm input state to the host controller is required, the alarm device must be wired directly to the host controller.
