Bosch B3512 - Installation and Control Panel Wiring (B208)

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).
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 58.
!
Caution!
Remove all power (AC and battery) before making any connections. Failure to do so might
result in personal injury and/or equipment damage.
Install the module
1. Set the module address using the address switches before you install it in the enclosure.
2. Install the module in the enclosure with the control panel or in an adjacent enclosure that
is within the distances rated for the module: 1000 ft (305 m) with 18 AWG to 22 AWG
(1.02 mm to 0.65 mm) wire.
3. Use the screws provided with the module to secure the module in the enclosure.
Wire to the control panel
When you wire an SDI2 module to a control panel, you can use either the terminal strip
labeled with PWR, A, B, and COM to wire to corresponding terminals labeled PWR, A, B, and
COM on the control panel, or you can use the interconnect wiring connector and the included
interconnect cable.
For terminal wiring, use 18 AWG to 22 AWG (1.02 mm to 0.65 mm) wire.
Notice!
Use either the terminal strip wiring or interconnect wiring to the control panel. Do not use
both. When connecting multiple modules, you can combine terminal strip and interconnect
wiring connectors in series.
