B901 Bosch Addressable SDI2 and SDI Access Control Door Controller
The B901 is a fully supervised, addressable access control interface module for compatible Bosch control panels using the SDI2 or SDI bus. It connects directly to standard five-wire Wiegand card readers and can supply either 5 VDC or 12 VDC reader power. The module is individually programmed through the connected control panel.
Inputs comprise one supervised door-contact point with a 1 k ohm end-of-line resistor and unsupervised tamper, Request to Exit and Request to Enter points. The Form C relay output is rated at 12/24 V and 2.0 A. The module operates from nominal 12 VDC, measures 73.5 x 127 x 15.25 mm and is specified for temperatures from 0 °C to +49 °C.
Key Features
- Fourteen programmable access-authority levels can be controlled by user level, user group, time, door state and area armed state.
- Locked, Unlocked, Secured and Fire Unlock modes provide four defined door-control states.
- Auto Door and Disarm on Open functions link door operation with the armed or disarmed state of the associated area.
- Heartbeat and reader-data LEDs indicate module operation, system errors and incoming card data.
- Supported credentials include 26-bit HID H10301 and EM-EM4200 formats plus 37-bit HID H10302 and H10304 formats.
