Off-board outputs

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

B308 octo-output module

The B308 is an eight output expansion device that connects control panel through 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 in the Installer Services Portal programming tool (available in
Europe, Middle East, Africa, and China) Help.
The control panels provide up to the following number of modules:
–
–
–
–
The module 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 series.
Notice!
UL Commercial fire and intrusion devices
Do not connect fire and non-fire devices to the same B308.
For detailed instructions, refer to the corresponding document listed in Related
documentation, page 12.
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 130.
11.1.2

Supervision

The control panel enables supervision of B308 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).
