Pelco DX1104-080 - Manual (Page 13)

ALARM OUTPUT MENU
The ALARM output on the rear panel is a single-pole, normally open, latching, dry contact. This output can be used to notify you if there has been
an alarm event that might require review. The alarm output can be enabled or disabled (armed/disarmed) manually, or it can be programmed to
enable (arm) or disable (disarm) at the same time automatically every day.
If the output is enabled and an alarm input is activated, the output relay will latch closed after a 20-second delay and will remain closed until it
is manually disabled. The 20-second delay allows you to enter your premises and disable the alarm output before it is activated.
The alarm output menu is used to set up automatic arming and disarming of the relay at specified times each day. (For manual operation, refer to
Alarm Relay Output Operation in the Operation section.) This feature may be used in conjunction with the event recording capabilities of the
DX1100 to notify you that an alarm event was recorded.
NOTE: The alarm output programming does not affect recording. It only affects the operation of the alarm output relay. For event (alarm)
recording, refer to Recording in the Operation section.
Application example:
A company has a rear door that is not to be opened for any reason between 5 p.m. and 7 a.m. During the day, the area around this door is
recorded continuously, but to conserve disk space, the area is only recorded at night if the door is opened. The owner does not want to review the
video unless the door was opened after hours.
In this case, the alarm output would be programmed to enable at 5 p.m. and disable at 7 a.m. The DX1100 would also be programmed for auto-
matic (continuous) recording from 7 a.m. to 5 p.m. and event recording from 5 p.m. to 7 a.m. (refer to
Camera Menu in the Programming section).
At 5 p.m. continuous recording would cease. If an alarm input is activated, the DVR would immediately begin recording the associated camera.
The relay would latch closed after the 20-second delay. When the owner returned in the morning, a light attached to the relay output would be
on, indicating that there was an alarm during the night. A search for recorded video starting at 5 p.m. would immediately take you to the first
alarm event. All other events could be reviewed in sequence.
