## Auxilary Equipment

### Music Source

The music output from a radio, tape recorder or similar item is fed into the system via the CPU-D_ ,
BTU-A(2) and BTU-C boards. By programming the exchange, the output from the connected equipment can be distributed throughout the system.

#### Technical data

Music input:

- Impedance: 600 ohm
- Voltage: 1 V max

#### Hardware installation

##### Connection to CPU-D2, CPU-D3, CPU-D4

To connect the music source output to the CPU-D_ board there exists two options:

1. Connection via the standard MDF cable TSR 902 0444 (Ericsson connector block ) or TSRBS 101 01 (Krone connector block).
   These cables will carry all feature connections from the CPU-D board to the MDF (Main Distribution Frame). Should the system already be using features like alarm input/output or temperature sensors, then there is already such a cable installed.

1. The wires from the music source output have to connected to the MDF connection block pin a1 and b1 (polarity independent).
2. Connect the cable to the position 4/3 on the CPU-D2, CPU-D3, CPU-D4.

2. Direct connection to the CPU by using the cable TSRBS 902 26/1.

1. Connect the music source output to the cable pair blue-white (pin A2 and A4 )
2. Connect the cable to the position 4/3 on the CPU-D2, CPU-D3, CPU-D4.

##### Connection to CPU-D5/CPU-D5C

Compared to the presessor CPU-Ds, the music source output can only be connected via a direct connection to the CPU-D5/CPU-D5C by using the cable TSRBS 902 26/1.

1. Connect the music source output to the cable pair blue-white (pin A2 and A4 )
2. Connect the cable to the position 6/1 on the CPU-D5/CPU-D5C.

##### Connection to BTU-A(2) or BTU-C

A twisted pair or a shielded cable should be connected from the music source output to the connector block of the standard MDF cable TSR 902 0444 (Ericsson connector block ) or TSRBS 101 01 (Krone connector block). Which of the individuals are used as music source input, depends on the customer configuration.

Refer to Connections to BTU-A2 and Connections to BTU-C

### Temperature Sensor

#### Function

The water proof temperature sensor(s) may be located outdoors to measure the outside temperature. The temperature is displayed on the system telephones with display. The temperature trend, increasing or decreasing, is indicated by” ^” for increasing and “v” for decreasing. Please note that the indication of the temperature trend, for the first 30 minutes after installation may not be correct (while reference values are being recorded).

#### Technical data

- Measurement accuracy:

- ± 0.5˚ C (between –24 ... +75˚ C)
- ± 1˚ C (between –40˚ C ... +100˚ C)

- Temperature range: –40 ... +75˚ C
- Maximum recommended line length: 50 m (twisted pair)

#### Hardware installation

The sensor(s) are connected to the exchange by a 10m long cable. If the sensor is to be placed outside it should preferably be mounted on an outside wall (with the supplied screw) that is not placed in direct sunlight. A desirable place is for instance a shady place under the roof. Do not try to place the sensor near a window that is often open for airing, or near an output for the ventilation. If the sensor is located more than 10 m from the exchange, we recommend to use a twisted pair cable normally used for extensions.

The following components are necessary to install the temperature function:

- Cable kit RPM 603 339/1 which contains:

- the cable with temperature sensor
- a wood screw

##### Connection to CPU-D2, CPU-D3, CPU-D4

To connect the temperature sensor(s) to the CPU board there exists two options:

1. Connection via the standard MDF cable TSR 902 0444 (Ericsson connector block ) or TSRBS 101 01 (Krone connector block).
   These cables will carry all feature connections from the CPU board to the MDF (Main Distribution Frame). Should the system already be using features like music output or alarm input/output then there is already such a cable installed.
   The wires are connected to the MDF connection block pins in the following way: (polarity independent)

- Temperatur sensor 1: a5 and b5
- Temperatur sensor 2: a6 and b6
- Temperatur sensor 3: a7 and b7

- Connect the completed cable to the position 4/3 on the CPU-D2, CPU-D3, CPU-D4.

1. Direct connection to the CPU by using the EURO connector RNV 321 0113.
   Solder the free ends of the temperatur sensor to the following pins.

- Connect the completed cable to the position 4/4 on the CPU-D2, CPU-D3, CPU-D4.

It is possible to connect 3 external temperature sensors to the CPU-D2, CPU-D3, CPU-D4, whereby only the values of the first one will be displayed on the system telephones with display (no settings necessary). The values of the 2nd and 3rd temperature sensor can only be read out via BMS.

##### Connection to CPU-D5/CPU-D5C

Compared to the presessor CPU-Ds, only one temperature sensor is supported which can only be connected via a direct connection to the CPU-D5/CPU-D5C by using the cable TSRBS 902 26/1.

1. Connect the free ends of the temperatur sensor to the cable pair green-red (pin C4 and C5 )
2. Connect the cable to the position 6/1 on the CPU‑D5/CPU-D5C.

### Alarm Equipment

#### Alarm signals of the CPU-D4

##### Connection to the CPU-D4 in a BP250, BP 50 or BP Compact cabinet.

To connect the alarm input/outputs to the CPU board use you have two options:

1. Connection via the standard MDF cable TSR 902 0444 (Ericsson connector block ) or TSRBS 101 01 (Krone connector block).
   These cables will carry the most common alarm connections (except the alarm relay outputs ) from the CPU board to the MDF (Main Distribution Frame). Should the system already be using features like music input or temperatur sensor then there is already such a cable installed. For the connection see figure below.
2. Direct connection to the CPU by using the EURO connector RNV 321 0113. For the connection see figure below.

##### Connection to the CPU-D4 in a BP 128i cabinet :

The 8pole Molex socket on the front panel provides:

- the CPU-D4s Alarm output together with the coupled Alarm relais switch - activated during the first second.
- the CPU-D4s Alarm input (polarity independent), and the Fan alarm output (to indicate the breakdown/stop of the needed air flow cooling followed after 5-10 minutes by an automatic system switch-off !).

The use of an outside temperature sensor is not supported.

Inside the BP128i cabinet the alarm socket (Molex type) and the 3,5 mm audio input jack are connected via the special cable (TSRBS 902 08/1) to the CPU-D4 board, whereas this cable includes the two wires with the fan breakdown alarm signal from the cabinet’s backplane.

The external alarm cable (TSRBS 902 10/1) is 3000 mm long and has a Molex plug on one end and an open end on the other side.

Pin assignment of the alarm socket for the CPU-D5 board with default wiring:

Fan breakdown alarm with the alarm input

Additional wiring needed:

1. Modify the internal cable (alarm and audio input, TSRBS 902 08/1) on the EURO connector for the CPU-D4 board position 4/3 in the following way:

1. Change the green‑white wire from B4 to C4 to make the ‑48 VDC available on pin 3 of the Alarm socket (Molex type). (Note: The CPU‑D4 Alarm output is then still available via the normally open contact given on the pins 2 and 4 of the Molex socket)
2. Change the blue‑white wire from A6 to A8 to make the ground pole (0 V) available on pin 1 of the Alarm socket (Molex type). Please compare pictures below.

1. Now the Fan breakdown alarm signal (5 VDC/20 mA) is used to activate the optocoupler-input of a ’Solid state relais’ (locally supplied, e.g.: Clare PLA140) providing isolated switch contacts.
2. The above mentioned -48 VDC can then be switched on via the contact of this ’Solid state relais’ to the pin 6 of the Alarm input (Molex socket). At last the pin 5 and pin 1 of this Molex socket must be interlinked to get the ground pole (see picture below).

External alarm tone: If another type of relais with 2 switches is available, then the other contact can be used to start e.g. an acoustic alarm tone (siren, horn) if needed.

The picture below shows this wirings of the alarm socket for the CPU-D4 board using the Fan breakdown alarm signal to activate via the Alarm input the 9A-alarm message of the ASB 150 02.

#### Alarm socket for CPU-D5/CPU-D5C

##### Connection to the CPU-D5/CPU-D5C in a BP250, BP 50 or BP Compact cabinet.

##### Connection to the CPU-D4 in a BP 128i cabinet:

##### Connection to the CPU-D5 in a BP 128i cabinet:

The 8pole Molex socket on the front panel includes:

- the CPU-D5 Alarm output together with the coupled Alarm relais switch - activated during the first second.
- the CPU-D5 Alarm input (polarity independent), and the Fan alarm output (to indicate the breakdown/stop of the needed air flow cooling followed after 5-10 minutes by an automatic system switch-off !).

The use of an outside temperature sensor is not supported.

Inside the BP 128i cabinet the alarm socket (Molex type) and the 3,5 mm audio input jack are connected via the special cable (TSRBS 902 08/1) to the CPU‑D5/CPU-D5C board, whereas this cable includes the two wires for the fan breakdown alarm signal from the cabinet’s backplane.

The external alarm cable (TSRBS 902 10/1) is 3000 mm long and has a Molex plug on one end and an open end on the other side.

Possible wirings of the alarm socket for the CPU-D5/CPU-D5C board:

The wire bridges 5 to 8 and 6 to 7 lead the 5 V/20mA Fan breakdown alarm signal directly to the CPU‑D5 alarm input (5 - 60 VDC). The picture above shows this wirings of the alarm socket for the CPU-D5/CPU-D5C board using the Fan breakdown alarm signal to activate via the Alarm input the 9A-alarm message of the ASB 150 02.

### Door Interface Unit (DIU) (BFYBS 10101/1)

#### Installation

The DIU is an interface connected via one or two extension lines to the ELU-A of the exchange and via a set of wires to the door phone. The DIU should be mounted indoors on a dry wall. The door phone can be of any commercially available type as long as it meets the requirements listed in the System Overview (1555‑ASB 150 02 Uen) under section Technical Data for DIU.

#### Connection

The wires to the speaker and microphone should be led via two twisted pairs in a separate cable. Caution when connecting a polarity-dependant microphone. Check polarity on connector x1. Make the connections to the door bell button, door opener and key lights etc in another cable. This is to minimise disturbances on the microphone line. The wires to the door opener carry more current and should have a diameter greater than 0.6 mm. The length between door phone and DIU should be less than 50 m. The length between door phone and exchange should be less than 500m.

The connector X18 is used for speech connection between DIU and exchange. The connector X17 is used to activate the door opener. If the door opener wiring already exists the X17 connection can be omitted and the connection X12 leads to an existing button.

Pressing the door phone button (connection X5) activates the DIU and the programmed extension rings (see Facility Description, 15534-ASB 150 02 Uen). The interface stays active for the preset time selected under "C" and shuts off after this time has elapsed.

#### Adjustments of DIU

The microphone level is factory set, but under certain conditions the line attenuation can exceed expectations resulting only in one way speech connection or clipping of the voice between extension and door phone. In this case cautious change of microphone level setting has to be performed as follows:

- If the voice in the speaker of the door phone sounds too dim or is clipped, turn the mic potentiometer screw two turns counterclockwise. Speak into the telephone microphone and verify that the speaker sounds loud and clear enough, otherwise repeat the adjustment.
- No voice connection to the speaker of the telephone.Turn the mic potentiometer screw two turns clock wise. Speak into the door phone microphone and verify that it is heard in the hand set of the telephone, otherwise repeat the adjustment.

#### Settings on the DIU board

### Alarm Interface Unit (AIU) (RPMBS 130 002/01)

The ALARM INTERFACE UNIT is an optional equipment mounted in the case bottom of the DBC 21x telephones. This equipment is used in the hospitality area to enable distress notification from e.g. a bathroom. A normally closed switch is installed and the two terminals are connected to the pins (button a and button b) on the option unit. The connection can be made in the wall outlet. Then the wiring shown above applies. If another type of wiring is used the connector Optional alarm can be used.
