5. EXTRA POSSIBILITIES WITH YOUR DOORGUARD300
a. Connecting an electric door opener
- To open the door from the monitor (figure 8).
- You need an electric door opener with its own power supply. The door-open-contact of the monitor
is a potential-free normally-open (NO) contact.
- The maximum load for this contact is: DC24V/1A or AC24V/1A.
- You need to connect the door opener onto the L+ en L- connectors of the monitor, using the
supplied cable.

b. Connecting multiple monitors
- To be able to see who is at the door from several places (max. 4). Upon that, you now have an
intercom system (figure 9). Available separately:
DoorGuard300
DoorGuard100
- Beware: Only the last monitor that you connect
should be switched on 75 Ohm.
- The remaining monitors are to be connected
parallel. The DoorGuard300 monitor is provided
with an extra connector for the connection of an
extra monitor.
- If you want to bridge a greater distance, then
check out the following table for the required
