Off-board points

The control panel supports off-board points using the B208 Octo-input Module.
13.1

B208 Octo-input Module

The B208 Octo-input Module is an eight point expansion device that connects to the control
panel through the SDI2 bus. This module is supervised and communicates back to the control
panel all point status changes. The module points work in the same way as the points on the
control panel.
B5512 control panels support up to 4 modules. B4512 control panels support up to 2
modules.
The B3512 does not support the B208.
The module connects to the SDI2 bus on the control panel using terminals PWR, A, B, and
COM, or using the SDI2 interconnect wiring connector. You can connect more than one
module to the control panel by wiring them in parallel. This section includes basic installation
instructions. For detailed installation instructions, refer to the Octo-input Module (B208)
Installation and Operation Guide.
Notice!
Do not connect fire and non-fire devices to the same B208 Octo-input Module in a UL
commercial fire installation.
13.1.1

SDI2 address settings

Notice!
The module reads the address switch setting only during module power up. If you change the
setting after you apply power to the module, you must cycle the power to the module in order
for the new setting to take effect.
If multiple B208 modules reside on the same system, each B208 module must have a unique
address.
The control panel model determines the number of points allowed and the valid addresses.
For valid point and address numbers, refer to B208 address settings.

Supervision

The control panel automatically enables supervision of B208 Octo-input Modules on the SDI2
bus when an associated point has its source programmed for Octo-input.
