VIDEO DOOR INTERCOM SYSTEM
Installation With Two Outdoor Cameras
This requires the use of the expansion junction box included with the S 9404A additional camera unit. The
junction box allows for a maximum of two indoor base stations and two outdoor camera units. See figure
5 for a wiring diagram of this system.
Operation
When installation is complete switch the power switch to the ON position. Adjust the volume level, bell
chime level, brightness and contrast as desired (you may have to unhook the unit from the wall bracket to
adjust some settings).
When a visitor presses the call button on the camera unit the monitor speaker sounds a chime tone. The
visitors image will appear on the screen. You may choose not to respond by not pressing the answer but-
ton, the visitors image will disappear within 30 seconds. To respond to a visitor you can press the answer
button and talk. The visitors image will remain on screen for 90 seconds or until you press the answer but-
ton again to hang up.
After speaking with the visitor, you may choose to open the door for them. To do this press the unlock
button. Note: You must have an electronic door strike installed in your system for this button to operate.
If you have two base stations installed in your sytem, you can press the call button to communicate with
the second location. This is ideal for two storey or larger homes as an internal intercom.
Optional Door Lock (Door Strike) Interface
To install door strike, select a 12V d.c. power supply with enough power (current) for your door strike. A
12V 1A d.c. plugpack such as the Altronics M 9274A should be suitable for most door strikes.
Drill cable entry hole in box containing PCB (PCB labelled ‘Altronics strike timer V1’). This box can be
located up to 20m from the door strike.
