Appendix B: Connecting Motion / Alarm Devices
Installing a Sensor on EDGE
+
series
You can connect external alarm input and alarm output devices to the system (i.e. motion sensors,
door/window sensors). Use a motion detector or sensor to send a signal to the system to begin
camera viewing and recording on the matching camera channel (when enabled in the Menu);
simultaneously, the system sends an output signal to a device such as an alarm or siren.
To connect an Alarm INPUT device to the system:
1. Connect the Signal Cable to the desired Channel
number in the alarm block (I1 = Input 1, I2=
Input 2 etc).
2. Connect the Ground cable to the Ground port (G)
in the alarm block.
NOTE: The alarm block connectors are
"push-type" connectors. To insert a wire, push the
plastic tab with a small, rigid object, and
simultaneously insert the wire.To release the
wire, push the plastic tab and simultaneously pull
the wire out.
To connect an Alarm OUTPUT device to the system:
1. Connect the ground cable to the COM port.
2. Connect the signal cable to the NO (normally open) or NC (normally closed) port.
To configure alarm in devices:
1. From the Main Menu, click to open the Alarm menu.
2. Use the Alarm Input & Output menu to configure alarm trigger settings.
