3.8.1 | 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].

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.
4 | 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.
5 | 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.
Flash Pattern

state. (blue)
ON Steady
LED trouble state: Module is not powered
(for OFF Steady only), or some other
trouble condition prohibits the module from
OFF Steady
communicating with the control panel.

6 | 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.
Figure 6.1: Firmware LED 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.
