Safety
ESD precaution
Please note that the B465 and optional cellular communication modules come in a plastic
bags, and are protected from ESD. All plug-in cellular communicator components may
potentially be exposed to finger touches - therefore extra attention must be paid to ESD
(electrostatic discharge) precaution. Make sure there is no static interference when using the
board. Appropriate ESD protections must be taken and wearing electrostatic equipment is
recommended, such as anti-static wrist strap.
ESD damage can range from subtle performance degradation to complete device failure.
Precision integrated circuits may be more susceptible to damage because very small
parametric changes could cause the device not to meet its published specifications.
Warning!
Failure to follow these instructions can result in a failure to initiate alarm conditions. Bosch
Security Systems, Inc. is not responsible for improperly installed, tested, or maintained
devices. Follow these instructions to avoid personal injury and damage to the equipment.
Notice!
Inform the operator and the local authority having jurisdiction (AHJ) before installing the
module in an existing system.
Disconnect all power to the control panel before installing the module.
The B465 Conettix Universal Dual Path Communicator (referred to as the B465) links the
PSTN digital dialer and/or dry contact inputs from a control panel to an IP connection
(Ethernet or Cellular) to the D6600 or D6100i Communication Receiver/Gateway through an
internet connection.
The need to reprogram the control panel’s automation from PSTN to IP operations is not
required when the B465 is installed. This conversion occurs within the Bosch Conettix
Receiver. All messages generated internally by the B465 are sent to the central station in
Contact ID format.
When the control panel’s PSTN dialer sends a message, the module simulates a public
switched telephone network (PSTN) connection to the central station. The module decodes
the control panel’s PSTN dialer report and sends the decoded reports by IP connection using
Bosch’s Conetix Protocol to the Conettix D6600, D6100IPv6, or D6100i Communication
Gateway/Receiver (referred to as the receiver). When the receiver acknowledges receipt of the
message, it sends an acknowledgement report to the module which in turn sends an
acknowledgement to the connected control panel. This process maintains true end-to-end
security.
The module has the following connections:
–Ethernet connects to the network
–dry contact programmable inputs (4x)
–3 programmable relay outputs, if necessary, to indicate conditions to the control panel, if
required
–Control panel Phone line inputs to the B465 (2x).
–B44x Cellular Module (optional)
–B46 External Annunciator (optional)

Module overview
The B465 Conettix Universal Dual Path Communicator allows any fire and intrusion control
systems with PSTN dialers and/or dry contact inputs to communicate with Bosch receivers to
the central monitoring station over Ethernet or cellular networks through IP. This allows
customers using control panels developed before the introduction of networking and cellular
to eliminate costly phone lines and gain some of the modern performance that IP networking
enables
The B465 Conettix Universal Dual Path Communicator is suitable for use with any one of the
–SIA (SIA8, SIA20)
This process described is why Bosch provides true end-to-end security. The module links the
control panel’s PSTN dialer to the internet and then to one of the Bosch Conettix receivers.
The B465:
–Connects with the control panel’s PSTN dialer or relay output connected to the B465
–Decodes and delivers alarm messages to a Conettix D6600, D6100i or D6100IPv6
–The Conettix receiver replies to the B465 with an acknowledgement of the message
–The B465 sends an acknowledgement back to the control panel through the PSTN

–Pulse 4/2 (2300 Hz ACK Tone)
–Pulse 4/2 (1400 Hz ACK Tone)

Digital communication
The B465 module uses its built-in Ethernet connection, and/or a Conettix Plug-in cellular
module (B440/B441/B442/B443) to send reports to the central station receiver. The system
routes event reports to the primary and backup destinations using ethernet or cellular
communication, depending on configuration.
Telephone line voltage
The module simulates a conventional phone line to the control panel it is connected with. The
module supplies a constant phone voltage of 28 VDC (on hook) to satisfy the connected
control panel's phone line monitor. The module's phone voltage is between 3-8 VDC when the
control panel attempts to communicate (off hook).
The module can be programmed to remove the phone voltage when there is a communication
failure between the B465 and connecting control panel. This allows the local control panel to
be notified that there is a problem by removing the phone line voltage from the terminal. This
causes a trouble to occur at the connected control panel as intended.
The B46 is an optional module that provides external B465 LED and sounder status when
installed in a supported enclosure. The module has 3 LEDs (System Trouble, Power, and
Battery) which illuminate through the B46 LED cover. The LED cover snaps into a knockout in
the enclosure door. The B46 fits in the B10/B10R, D8103 enclosure. Refer to the following

3 ー B46 Cable (P/N: F01U310747) included with the B46
Notice!
The white wires of the B46 cable should be facing the words “EXTERNAL ANNUNCIATOR.”
Notice!
Ensure the placement of the B46 cable does not obstruct the LEDs of the B465 when
inserting into the port of the B465.
4.8.5
Input loop wiring
The B465 provides four on-board inputs. Each input functions independently and does not
interfere with the operation of the others. The module monitors the input loops for normal,
shorted, or open conditions between an input terminal and any of the input common
terminals.
The programming for the input determines how the module responds to these conditions.
The module ignores input loops for 120 seconds after power up to ensure that the
connections have stabilized.
Input loops
Install a 2.21 kΩ resistor at the far end of the input loop when wiring the on-board inputs to
provide a reference for supervision. The total resistance for the wire length and contacts,
minus the end-of-line (EOL) resistor, must not exceed 100 Ω.
6 ᅳ Combination: Normally open contacts and normally closed contacts (NO/NC)
7 ᅳ2.21 kΩ EOL resistor (P/N: F01U034506)
8 ᅳ Red
9 ᅳ Brown
Notice!
You do not need to install the End of Line (EOL) resistor for unused inputs (inputs are
disabled by default).
UL does not permit normally closed loops for commercial fire applications.
Input voltage parameters
You can determine the condition of on-board inputs 1 to 4 by measuring the voltage across the
input terminal (1 to 4) and the point COM terminal. The loop wiring must be connected and
the 2.21 kΩ EOL resistor must be in place and the input function programmed.
