Configuring Normal Input States for Alarms
IMPORTANT
Some controllers allow the normal input states for domes to be specified at the
controller. These controllers include VM96, AD matrices with AD2083-02A code units
or AD168 matrix with the AD168CCM or AD2083-02A code unit. Do not use both the
dome configuration utility and the controller to assign the normal input states. Use only
the dome configuration utility or the controller to assign the normal input states.
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.
IMPORTANT
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.
