Pelco Manual C1487M-D (7/99) 27
In certain situations, the dome will respond as follows:
• If a preset has not been set, but an alarm is connected: the dome will go to a factory
preset that will not be the desired position.
• If one alarm is a preset and another is a pattern and both are received: the dome will
alternate between them.
An alarm clears by returning to its former (off) state.
Depending on choices made on the programming menu, the dome can respond to an alarm
by running one of the patterns below. (Refer to the
Patterns
section for more information.)
• Run full pattern
• Run half pattern 1
• Run half pattern 2
When sequencing between presets, the dwell time depends on the time set on the Alarm
Dwell submenu for that preset. After the dwell time expires, the dome immediately does
one of the following:
• If the resume feature was selected on the programming menu and there are no other
alarms activated, the dome resumes its prior activity. So, it might return to its previous
position or resume a scan or pattern.
• If there are other alarms activated, the dome goes to them.
If you move the joystick to pan or tilt the dome, or if you issue a lens command while there
is an alarm, the pan and tilt or lens command overrides the alarm. Sixty seconds after the
last pan and tilt or lens command, the dome will return to the alarm preset if the alarm is
still active.
AUXILIARY OUTPUTS
(This section applies to Spectra II™ only.)
An AUX 1 command from the controller will activate the relay in the dome and operate the
device that is connected to the relay. The relay will remain latched until a clear command is
issued.
An AUX 2 command from the controller will place a ground at the output of AUX 2 to
operate the device that is connected to it. The output will remain latched until a clear
command is issued. Refer to the
Back Box Connections
section for precautions regarding
the use of the AUX 2 output.
The output relay can also be programmed so that it is activated when any alarm input is
activated. When latching (toggling) is selected on the programming menu, giving the AUX 1
command from the controller changes the state of the AUX (for example, if it was on, this
turns it off.) The clear command from the controller will turn the AUX off in the latching or
toggle mode.
PARK
If the dome does not receive any commands for a specified period of time (refer to the
Park
Time Minutes
section), the dome will go to preset 1 and park. If the time specified is zero,
or if preset 1 has not been programmed, the dome will not park. The default is zero
minutes.
