Off-board points

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

B208 Octo-input Module

The B208 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.
The B6512 supports up to 9 modules. The B5512 supports up to 4 modules. The B4512
supports up to 2 modules.
The B3512 does not support the B208.
The module connects to the SDI2 bus on the control panel using SDI2 terminals, 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 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, page 128.
13.1.2

Supervision

The control panel automatically enables supervision of B208 on the SDI2 bus when an
associated point has its source programmed for Octo-input.
With any failure to receive an expected response from the module, all keypads show a system
fault. The control panel sends a module trouble report to the central station (if configured for
module trouble reports).
13.1.3

Installation and control panel wiring (B208)

Ensure that there is enough power for the module and other powered devices you want
connected to the system.
Refer to On-board outputs, page 50.
Caution!
Remove all power (AC and battery) before making any connections. Failure to do so might
!
result in personal injury and/or equipment damage.
