The Bosch B920 Two-line Alphanumeric Keypad (SDI2) is a sophisticated interface designed for intrusion alarm systems, offering clear communication and intuitive control. This SDI2 bus compatible device features a 2-line LCD display capable of showing up to 32 characters, which allows for detailed point, user, and area names. The display utilizes words, numbers, and symbols to convey the security system's status, prioritizing events when multiple occur simultaneously. This ensures users are always informed about the most critical system activities.
The keypad's user interface is menu-driven, simplifying operation through dedicated function buttons for common commands. These include direct access to status indications, making it easy to check the system's current state. For enhanced usability, the B920 provides situation-sensitive on-screen help, guiding users through various operations and making system management straightforward, even for those less familiar with security systems.
Visual indicators are a key feature of the B920, providing quick and clear feedback on the system's status. Highly visible indicators show when the system is armed, ready to arm, or in an alarm state. Additionally, there are dedicated indicators for power status and gas alarms, including carbon monoxide (NFPA 720), ensuring critical alerts are immediately noticeable. These visual cues are complemented by the keypad's backlighting, which illuminates when keys are pressed or when an audible tone is emitted, improving visibility in low-light conditions.
The B920 keypad is equipped with 10 number keys, 7 function keys, and 6 navigation keys, offering comprehensive control. The function keys are programmable, allowing users to customize shortcuts for frequently used commands, such as initiating arming or bypassing with a single keypress. This level of customization enhances efficiency and user convenience.
Audible tones are an integral part of the B920's alert system. The built-in speaker produces several distinct warning tones, each differentiated to help users recognize the type of event without needing to look at the display. These tones are particularly useful for alerting personnel to fire events, and in commercial settings, they can assist firefighters in locating the keypad during an emergency. Users have the option to silence these audible tones using a passcode, providing flexibility in managing alerts.
Installation of the B920 is designed for simplicity and efficiency. The keypad features a self-locking base and chassis design, which streamlines the mounting process. A built-in bubble level further aids in achieving a precise and level installation. For mounting in various environments, such as concrete or block, an optional B56 Keypad Surface Mount Box is available. When replacing older keypads, the B96 Keypad Trim Bezel can be used to cover the previous wall footprint, ensuring a clean and aesthetic finish with the new, slim design of the B Series keypads.
The B920 is intended for indoor use in dry locations. For commercial applications, it is recommended to install the keypad in building entrances and areas with unrestricted access. Placing keypads near exterior doors in hotel or business lobbies allows for quick identification of emergency types and locations. In residential settings, keypads are typically installed near front and rear entrances, with additional keypads often placed in kitchens or bedrooms for convenient access.
For larger buildings with multiple security areas, the B920 supports the use of multiple keypads. These keypads can be programmed to control different areas, providing granular security management. The audible tones generated by the keypad sounder not only alert personnel to events but also serve as a crucial aid for firefighters in locating the keypad during fire emergencies.
Maintenance features include user-adjustable options for volume and display brightness, allowing users to customize the keypad's settings to their preferences and environmental conditions. The keypad's robust construction, utilizing Acrylonitrile Butadiene Styrene (ABS) and Poly(methyl methacrylate) (PMMA) for the display window, ensures durability and longevity.
The B920 is compatible with a range of Bosch control panels, including B9512G/B9512G-E, B8512G/B8512G-E, B6512, B5512/B5512E, B4512/B4512E, B3512/B3512E, and D9412GV4/D7412GV4, ensuring seamless integration into existing Bosch security systems. Power and data requirements are supplied through a four-wire connection from a compatible control panel. The sliding self-locking enclosure also features custom gap-free, lift-gate style terminal blocks, further simplifying wiring and installation.
The B920 Two-line Alphanumeric Keypad (SDI2) is designed to provide a reliable, user-friendly, and highly communicative interface for managing intrusion alarm systems, combining clear visual and audible feedback with flexible control options and straightforward installation.
