Bosch B901 - Access Control Interface Module Installation Manual

Overview

The B901 Access Control module is a fully supervised SDI2/SDI device that allows access control integration for compatible control panels. Each module can store up to 2000 user tokens (on SDI2), each with a different access level for each door. Authority for access is controlled by the user's authority level, the time of day, the state of the door, and the armed state to the module.

Address settings

Two address switches determine the address for the B901 Access Control Module. The control panel uses the address for communications. The address also determines the output numbers. Use a slotted screwdriver to set the two address switches.

NOTICE!
The module reads the address switch setting only during power up. If you change the switches after you apply power to the module, you must cycle the power to the module in order for the new setting to be enabled.

Set the address switches per the control panel configuration. If multiple B901 modules reside on the same system, each B901 module must have a unique address. Figure 2.1 shows the address switch settings for address 01.

Valid addresses for SDI2

Valid B901 addresses are dependant on the number of modules allowed by a particular control panel.

Valid addresses for SDI

Valid B901 addresses are dependant on the number of modules allowed and the desired failure mode (Fail Safe, Fail Secure) by a particular control panel.

Installation

After you set the address switch for the proper address, install the module in the enclosure, and then wire it to the control panel.

Remove all power (AC and battery) before making any connections. Failure to do so might result in personal injury and/or equipment damage.

NOTICE!
B901 tamper generates an SDI - "Missing Door" or an SDI2 - "Module Tamper" message (if Enclosure Tamper parameter is set to Yes).

Mount the module in the enclosure

Mount the module into the enclosure's 3-hole mounting pattern using the supplied mounting screws and mounting bracket. Refer to Figure 3.1.

Mount the access card reader

Refer to your access card reader installation instructions for proper installation and maintenance procedures related to your supported card reader.

Wire to the SDI2 control panel

When you wire the module to a control panel, use the control panel terminals labeled R, Y, G, B (PWR, A, B, COM). Connect them to the module terminals labeled R, Y, G, B (PWR, A, B, COM). Use either terminal strip wiring or interconnect wiring connector to the control panel. Do not use both. Refer to Figures 3.2 - 3.3.

Wire to the SDI control panel

Wire to the card reader

Use the terminals labeled LED, DATA1, DATA0, 5.2V or 12V, COM, and T+ when wiring the module to a card reader. Refer to Figure 3.4.

Wire to 12VDC power supply (optional)

Refer to Figure 3.5 to wire additional power to a regulated powerlimited power supply for fire protective signaling units and commercial/ residential burglar units.

NOTICE!
Use only Access Control listed power supplies for powering door strikes.

Wire to the door strike

A relay provides a dry contact single pull double throw output. Some strikes require a closed circuit to unlock the door, while others require an open circuit to unlock the door.

• Common (C). For 12/24 VDC strikes, provide input power here from the power supply. Refer to Figure 3.6.
• Normally closed (NC). For door strikes that require an interruption of power to open. Connect the positive side of the door strike to the NC terminal. Refer to Figure 3.6.
• Normally open (NO). For door strikes that require power to open.
  Connect the positive side of the door strike to the NO terminal. Refer to Figure 3.6.
  

Wire to door contact

Request to Enter (RTE)

Wire the Request to Enter (RTE) device. The strike is activated, and the door point is shunted when RTE is momentarily shorted to COM. The Shunt only option shunts the point when this input is momentarily shorted. To activate the shunt but not the strike, program RTE Shunt Only? as [YES].

Request to Exit (REX)

Wire the Request to Exit (REX) device.

The strike is activated, and the door point is shunted when REX is momentarily shorted to COM. The Shunt only option shunts the point when this input is momentarily shorted. To activate the shunt but not the strike, program REX Shunt Only? as [YES].

NOTICE!
Do not use a Request to Exit device (REX) for emergency exit applications. NFPA 101 requires that a UL Listed panic device be used to provide direct power from the standby power source. Check with your local Authority Having Jurisdiction (AHJ) prior to installing your system.

Configuration

After you wire the module, power up the system and configure the B901 using Remote Programming Software (RPS) to assign the module to an assigned area. Whenever possible, be consistent when numbering doors, areas, and keypads. For example, assign Door 1 to Area 1 and keypad 1. Test for proper operation.

LED descriptions

The module includes one blue Heartbeat LED, and one Reader LED. The Heartbeat LED indicates that the module has power as well as a module's current state. The Reader LED indicates data transmission. Refer to Table 5.1.

Table 5.1: LED descriptions

Flash Pattern	Function
Flashes once every 1 sec	Normal state: Indicates normal operation state. (blue) LED trouble state: Module is not powered
ON Steady
OFF Steady	(for OFF Steady only), or some other trouble condition prohibits the module from communicating with the control panel.
Flashes rapidly	Card data is executing (yellow)
OFF Steady	No card data is being received

Show the firmware version

To show the firmware version using an LED flash pattern:

• If the optional tamper switch is installed:
  With the enclosure door open, activate the tamper switch (push and release the switch).
• If the optional tamper switch is NOT installed: Momentarily short the T+ terminal.
  Refer to Figure 6.1 for an example of flash patterns.
  

When the tamper switch is activated, the heartbeat LED stays OFF for 3 sec before indicating the firmware version. The LED pulses the major, minor, and micro digits of the firmware version, with a 1 sec pause after each digit.

In the following example, the version 1.4.3 shows as LED flashes:
[3 sec pause] *___****___*** [3 sec pause, then normal operation].

NOTICE!
Firmware reprogramming on the B901 is not supported if connected via the SDI bus. Updating the firmware is achieved via the SDI2 connection only.
