Product Overview

The Bosch Solution CM796B Wiegand to RS485 LAN Module enables compatible third-party Wiegand proximity readers to connect with Bosch Solution 144 and Solution 6000 alarm panels. It supports Wiegand credential formats from 26-bit to 40-bit, making it suitable for sites that want to retain existing readers, access cards or user credentials while integrating them with a compatible Bosch intrusion and access-control system. The module connects through the panel’s encrypted RS485 LAN and operates as a keypad or reader device. Reader LED and buzzer control, a tamper input, diagnostic indicators and a separately fused reader power input support professional alarm and access-control installations.

Key Capabilities

Wiegand Reader Integration

Connects supported third-party Wiegand proximity readers to compatible Bosch Solution alarm panels.

26-Bit to 40-Bit Support

Supports common Wiegand credential formats from 26-bit through to 40-bit.

Encrypted RS485 LAN

Communicates with the alarm panel through the Bosch encrypted RS485 system LAN.

Reader LED and Buzzer Control

Provides supported visual and audible feedback through compatible reader indicators and sounders.

System and Door Control

A connected reader can be configured for alarm area control, door access control or both where supported.

Diagnostic Indicators

Status, reader and error LEDs provide installation, communication and troubleshooting feedback.

Best For

  • Existing Wiegand Installations: Retains compatible readers and credentials when upgrading to a Bosch Solution 144 or Solution 6000 panel.
  • Commercial Alarm Systems: Suitable for offices, warehouses, retail premises and industrial facilities requiring reader-based system control.
  • Combined Alarm and Door Access: Supports applications where a reader is used for alarm area operation, door control or both.
  • HID and Third-Party Readers: Provides an interface for supported industry-standard Wiegand reader hardware.
  • Credential Migration Projects: Helps preserve compatible existing access cards rather than replacing every reader and credential.

Why Choose the CM796B

Choose the Bosch CM796B when a Solution 144 or Solution 6000 installation needs to use compatible third-party Wiegand readers instead of proprietary LAN readers. Its support for 26-bit to 40-bit formats makes it practical for sites with established reader hardware and credential databases. The module operates as a reader device on the encrypted RS485 LAN, records supported access events in the panel log and provides LED, buzzer and tamper integration. Separately fused reader power and onboard diagnostic indicators support easier installation and fault finding. Security Wholesalers supplies the CM796B for professional Bosch alarm and access-control integrations.

Buyer Decision Tips

Buyer Tip: Confirm that the existing proximity reader outputs a supported 26-bit to 40-bit Wiegand format and that its credential format is configured correctly in the panel.

Buyer Tip: Each CM796B consumes one keypad or reader address on the Bosch LAN, so allow for the total number of installed keypads and reader devices.

Power Note: Plan a suitable reader power supply and verify the current requirements of the reader, door lock and other connected equipment before installation.

Choosing the Right Model

  • Choose this module if: The system uses a Solution 144 or Solution 6000 panel and needs to accept a compatible 26-bit to 40-bit Wiegand reader.
  • Check panel firmware: Confirm that the panel meets the required firmware version before installation and programming.
  • Check credential format: Verify the reader output, card bit format, facility code and credential numbering before migrating users.
  • Check available addresses: Each module occupies a keypad or reader address and must use a unique address on the RS485 LAN.
  • Check power requirements: Size the external power supply for the connected reader, lock and any other equipment rather than relying on the panel LAN without calculation.

FAQs

  1. What does the Bosch CM796B module do?
    The CM796B converts the output from a compatible Wiegand proximity reader for communication over the Bosch encrypted RS485 LAN. This allows supported third-party readers and credentials to operate with compatible Solution 144 and Solution 6000 alarm panels.
  2. Which Wiegand formats does it support?
    The module supports Wiegand formats from 26-bit to 40-bit. The reader and credentials must use a compatible format, and the relevant bit structure, facility code and user details must be programmed correctly in the panel.
  3. Can the CM796B be used with both Solution 144 and Solution 6000 panels?
    Yes. It supports the Solution 144 from firmware version 2.08 and the Solution 6000 from firmware version 2.12. The panel firmware and programming options should be checked before installation.
  4. How many CM796B modules can be installed?
    Up to 15 modules are supported on a compatible Solution 144 or Solution 6000 system. Each module consumes one keypad or reader address, so the actual number available also depends on the other devices already connected to the LAN.
  5. Can a connected reader control the alarm and a door?
    Yes. Depending on panel programming and connected equipment, the reader can be configured for alarm area control, door access control or both. The door lock, power supply and required control hardware are supplied separately.
  6. Does the module control the reader’s LED and buzzer?
    Yes. The CM796B supports compatible reader LED and buzzer functions, allowing visual and audible feedback for system states and selected events. Available behaviour depends on the reader wiring and panel programming.
  7. Does the CM796B power the connected reader?
    The module provides a separately fused external power input for the Wiegand reader. A suitable power supply should be selected according to the reader, lock and total system current requirements.
  8. What should I check before buying the CM796B?
    Confirm the panel model and firmware, reader Wiegand format, credential structure, available LAN address, reader power requirements and planned alarm or door-control functions. Security Wholesalers can supply the module for compatible Bosch Solution installations.
