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

CAUTION!

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

3.1 | 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.

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.

2 | 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.

Figure 2.1: Address switches

NOTICE!

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

NOTICE!

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

3.7 | 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.

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.

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].

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.

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

3.8.2 | Request to Exit (REX)

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.
