Installation Manual

B942 Touch Screen Keypad
The B942/B942W is an SDI2 bus compatible device. Each keypad has a credential reader, a
presence sensor, a graphical interface for controlling the system, and touch screen keys for
data or command entry.
Each sensor loop is assigned a point number. The keypad transmits sensor loop status to the
control panel individually. The control panel detects open, short, and normal circuit conditions
on the keypad sensor loops.
The keypad includes one output.
Shortcuts and custom functions
B Series intrusion keypads include a Shortcuts feature. Shortcuts allow you to assign
commonly used or custom functions to a Shortcuts menu. You create and assign shortcuts to
keypads using RPS.
Custom functions
Custom functions allow you to combine multiple functions into a single function. Initiate
custom functions from keypads by assigning them to the Shortcut menu.
Use RPS to create custom functions, give them a name, and assign them to a Shortcut.
The user must have the appropriate authority level enabled to use the custom function.
For more information on creating custom functions, assigning authority levels to the functions,
assigning custom functions to a keypad’s Shortcuts, and other methods for initiating custom
functions, refer to RPS Help or the control panel Program Entry Guide.
Address settings
The control panel uses the keypad’s address setting for communication and bus supervision.
If multiple keypads reside on the same system, each keypad must have a unique address even
when on different buses.
B94x/B93x/B92x keypads
B93x and B92x keypads use two hardware address switches. The B94x keypads use two
virtual (on-screen) switches that mimic the hardware switches. For single-digit addresses 1
through 9, set the tens switch to 0. The figure shows the keypad switches set to 1:
Supervision
The control panel supervises all enabled SDI2 keypads.
Any failure to receive an expected response from a keypad results in a system fault (missing
keypad) shows on all keypads. The control panel sends a keypad missing report to the central
station, if configured.
Installation and control panel wiring (keypads)
Ensure that there is enough power for the keypad and other powered devices you want
connected to the system.
Refer to On-board outputs, page 60.

1. Open the keypad.
