7902 - 7905 | Installation and Operational Manual
The alarm/action box performs two distinct functions:
1. Action
This function, for example, opens a door remotely.
Pressing the action button of the system monitor activates a relay
contact. This contact (N.O., N.C.) can activate, for instance, a door
opener.
Note that the action button only activates the action box designated
to the camera input whose picture is shown on the monitor screen.
2. Alarm
This function provides alarm inputs to the security system. All kinds
of detectors having a N.O. or N.C. contact are supported, for
example:
•
infrared detectors
•
smoke detectors
•
magnetic door/window contacts
When a detector triggers the alarm/action box, the system monitor
automatically switches to the camera input the alarm/action box is
designated to. The system monitor produces an alarm and activates
its alarm contact.
There are two versions of the alarm/action box: one with a Passive
InfraRed (PIR) motion detector and one without. The description in
this manual applies to both versions.
