Off-board outputs

The control panel supports off-board outputs using the B308.
11.1

B308 Octo-output Module

The B308 is an eight output expansion device that connects control panel through the SDI2
bus. This module is supervised for the connection to the SDI2 bus. It provides eight
independently controlled outputs. Each output can operate as either normally open or
normally closed. You can configure the function for each output on the module individually.
Refer to Output Parameters in RPS Help or the control panel Program Entry Guide.
The B6512 supports up to 9 modules to provide 72 outputs. The B5512 supports up to 5
modules to provide 40 outputs. The B4512 supports up to 3 modules to provide 24 outputs.
The B3512 does not support the B308 module.
The B308 connects to the SDI2 bus on 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-output Module (B308) Installation and Operation
Guide.
Notice!
Do not connect fire and non-fire devices to the same B308.
Outputs overview
Each module output provides a Form C dry contact rated for .001 to 1.0 A at 5 to 24 VDC
(resistive load). Normally-open, common, and normally-closed terminals are available for each
relay output. When an individual output is activated, continuity exists between the normally
open and common terminals. When the output is not activated, continuity exists between the
normally closed and common terminals.
11.1.1

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 B308 modules reside on the same system, each B308 module must have a unique
address.
The number of outputs allowed by the control panel determines the valid addresses.
For valid output numbers, refer to B308 address settings, page 128.
11.1.2

Supervision

The control panel enables supervision of B308 Octo-output Modules on the SDI2 bus when the
Output Source of an off-board output is set to Octo-output.
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).
