July 2018 Operations Manual CB901EX
INTRODUCTION
Ring-Master system CB 901EX is an all-to-all direct speech system, controlled by a fully
electronic central e change. All its functions are microprocessor controlled. This enables the customer
to select from a wide range of programmable features designed to achieve fle ibility and optimal
efficiency in internal communication.
A built-in Lithium battery will secure all programmed information up to 10 years when power
to system is switched off.
The modular structure of the central permits easy e pansion, station by station, from 2 up to a
capacity of 7.000 subscribers. Moreover, a wide variety of station types, matching the needs of almost
any user, whether institutional, industrial or commercial applications, increases the fle ibility of the
system.
The unique cabling concept provides the advantages of both centralized and decentralized
cabling arrangements. Each station requires one single pair for dialing and conversation. Power can
either be individual to each station or remote groups of stations can be supplied from local mains
power units. The cabling is ordinary telephone wires.
The central unit is compact. A standard basic cardrack equipped for 80 subscribers measures
only 256 mm 570 mm 271 mm (10.1" 22.4" 10.9"). Silent in operation, once fitted with its
cover, the central can operate inconspicuously in almost any location.
In a single-Stage system, the central unit consists of a Basic Cardrack DP 979 containing the
Basic Cardset and Subscriber Cards, totaling 88 subscribers. If the number requirements e ceed this, an
additional Subscriber Cardrack DP 980 is necessary, giving a ma imum capacity of 240 subscribers in
a single-stage system.
Each single-stage of 240 numbers is equipped with 15 internal links.
The number of subscribers in a CB 901EX system may be e panded in steps of 8, plugging in
subscriber cards.
The basic cardrack 10 subscriber cards = 80 subscribers
The subscriber cardrack 20 subscriber cards = 160 subscribers
Giving a ma imum capacity of 240 subscribers, each with access to the 15 links.
Each stage in the central unit consists of a basic cardrack for the common basic cardset, and
according to the number capacity, an additional subscriber cardrack.
All cards in a CB 901EX system are of plug-in type, interconnected via the motherboard in each
cardrack.
The CB901EX printed circuit cards, are briefly described in the following:

CB901EX Operations Manual July 2018
PROCESSOR CARD
This card contains the microprocessor, its program and memory.
The 256K bytes program, which controls all computer operations is located in FLASH Memory).
It contains the main oscillator (10.7 MHz) and provides all timing signals in the central unit. In this
way the system is synchronized all the way through, which minimizes noise generation on the audio
links. This card also sets up/disconnects links, directed by the processor. It handles the PAM (Pulse
Amplitude Modulation) sampling control for all links. There are 32 time-slots in the system. One time-
slot is allocated by the subscriber scanner and one for the tone receiver, leaving 30 time-slots for audio
connections. This means that there is room for 15 simultaneous audio links.
AUDIO CONTROL CARD
The duple voice control circuits are located on this card, together with the receiver and tone
transmitter. The processor fully controls the tone receiver/transmitter.
The duple control circuit operates individually for each time-slot, which is much faster than the
processor can manage. Therefore, a separate control system is included on this card.
LINK CARD (2 cards)
It connects the audio signals between the subscribers. Each card handles 8 links and there are
always 2 link cards in the central unit.
POWER CARD
It contains a switching power supply, synchronized with the main oscillator to minimize noise.
Input to the card is 25 - 28V DC.
PROGRAM DISTRIBUTION CARD
It interfaces the intercom system to an e ternal program source and allows the subscribers to
activate and connect program- (music) and alarm channels.
SUBSCRIBER CARD
It terminates the lines for 8 subscribers, and is the interface card between the stations and the central unit.
The card splits up the audio/signaling information to/from the subscribers. All subscriber cards are identical.

FEATURE DESCRIPTION
HANDSET / LOUDSPEAKING
When two intercom stations are connected, either party may speak to the other hands free without
touching any buttons.
CONFIDENTIAL /SOFTSPEAKING
At any time during the call, either one or both parties may pick up their station ( AA918) and
use it as a handset for a confidential conversation. When both parties are in handset mode,
the system operates in open duplex mode and both parties may talk and listen at the same
time.
SIMPLEX
The T-button may be used to control the speech direction (push to talk release to listen). This is
useful when one of the intercom stations is in a noisy area. Either party may use this function. If both
stations are pushing the T-button the control is given to the station that pushed T last. Either party may
revert to handsfree mode by tapping the T-button. Any call number may be programmed with the
privilege “simple always” . When a call is placed from or to a station with the “simple always”
privilege, the initiator will be in listen mode and the T-button must be used to change the speech
direction.
MICROPHONE CUTOFF
To temporarily mute the microphone during conversation, the mute button may be pressed down.
DIRECT DIALING
It is possible to program keys 0 to 9 of each intercom station’s keypad to speed dial frequently
called numbers. When a programmed key is pressed, a dialtone is heard as normal. If a second key is
pressed within 1.2 seconds (programmable subscriber timer) then a normal dial sequence is taken.
DIRECT ACCESS
It is possible to program one call number for each intercom station to be activated by short DC-
shift (<1 sec). This type of calling is used with door stations and elevator stations that do not have a
tone dialer.

CB901EX Operations Manual July 2018
ALARM
Long DC shift (1sec<) will send ALARM to the call number programmed for direct access.
LINE SUPERVISION
Line Supervision is activated with privilege #10. Zero Volt on the audio line will send FAULT
to the call number programmed for Direct Access.
TWO BUTTON DC SHIFT SUB-STATION
Direct Access and Direct Dial #1 are programmed to activate this feature.
Short DC shift(<1sec) will send CALL to the call number for Direct Dial #1.
Long DC shift (1sec>) will send ALARM to to the call number programmed for Direct Access.
Zero Volt on the audio line will send FAULT to the call number programmed for Direct
Access.
Device Type = sub
Program in Que = none
REMOTE CONTROL
DTMF tones may be sent from one intercom station to the other for remote control. The keypad on
the station sends standard telephone dialing tones (CCITT). This is mainly used for electric door-lock
release and for dialling out to the public telephone network (PTT). The microphone mute function must
be activated while pushing a number key to disable conference add-on . When the B-subscriber
(receiver of the call) is programmed with the privilege “DTMF Device” then the number keys may be
activated without pushing the microphone mute key.
CAMP ON BUSY EXTENSION
The caller may camp-on to a busy e tension for 20 seconds (programmable subscriber timer),
after which the call will be automatically cancelled. If the called party becomes free within this time,
the connection will be established with warning tone to both parties.
PRIVACY
The stations privacy switch controls the privacy status. When the B-subscriber is in privacy both
stations get the ringing tone. The B-subscriber may accept the call by pressing the 0-button within 15
seconds (programmable subscriber timer). This operation is valid when the B-subscriber is not using
personal queue.
