Dwg. 3 Floor panel with color camera, Commax type (DRC-4CG).
Service of installation procedure (requires activation in CD system)
During activated monitoring from the camera of CD system and hung up receiver we
should press quickly five times pushbutton CONTROL (signalling diode will light also in
red) and then pick up the receiver and press pushbutton LOCK. Electronic cassette of
CD system will search monitor after founding it monitor number will be reproduced
in the loudspeaker. Sound signals will be generated according to the number of hundreds,
tens and unities of the programmed number. Longer break means passing to next digit
in the programmed number and longer duration of sound signal means zero value of
a given digit.
If pushbutton LOCK is not pressed within 30 sec the procedure will be stopped automatically.
After finishing of number reconstruction it is possible to select calling signal for this
monitor by sequential pressing pushbutton LOCK; short press of receiver`s hook causes
changing calling volume. Four volume modes are possible: quiet, intermediate, loud and
increasing (three short signals of increasing frequency).
After having made the changes the receiver should be hung up, then the centre will call
back to monitor and the fitter will be able to check the functioning of acoustic track and
electro-catch.
3. Gate drive control
Pressing a PROG button causes a short circuit terminal BR to the GND.
Two modes of gate drive control are possible - only during conversation and with receiver
picked up. To change this mode pushbutton PROG (backside of monitor) should be
pressed during pushbutton CONTROL pressed and the receiver hung up. Another
pushbutton PROG keystroke switches mode. Actual mode is signalled by signalling diode
- green color means gate drive control during conversation and red color means gate
drive control with receiver picked up. Gate drive control during conversation is default
mode.
It is recommended itself use relay to control any external device. To secure relay against
supertension polarized diode should be connected parallel to coil of repeater (see dwg. 4).
CAUTION!!
To terminal BR don't connect any source of voltage!
4. Monitor programming
In standard delivery in each monitor number 63 is programmed. This is a test number
and even in apartment 63 it should be programmed again.
Programming should be done directly after monitor connection and before its mounting.
