12.0SDI Devices

12.1Description

D9412GV3 and D7412GV3 Control Panels can support a number of accessory devices from the SDI Bus using Terminals 29 through 32. Some devices include the D1255 and D1255B Keypads (refer to Section 11.0 Arming Devices on page 55), D9131A Parallel Printer Interface Module, D9210B Wiegand Control Interface Module, DX4010i RS-232 Serial Interface Module, ITS-DX4020-G GPRS/GSM Communicator, and DX4020 Network Interface Module.

For UL 864 Commercial Fire applications, refer to Installing Combination Fire and Intrusion Alarm Systems in the D9412GV3/D7412GV3 Approved Applications Compliance Guide

(P/N: F01U143069) for important information about combination fire and intrusion systems.

12.2Installation

For complete installation instructions, consult the operation and installation guide for the specific SDI device. SDI devices connect to the control panel in parallel (Table 21).

These devices can share power with the control panel or be powered by a stand-alone power source.

Table 21: SDI Device Connections

D9412GV3/D7412GV3		SDI Devices
Terminal	Function	Wire Color	Function
32	POWER +	Red	+12.0 VDC
31	DATA BUS 1	Yellow	Data
30	DATA BUS B	Green	Data
29	COMMON	Black	Common

A stand-alone power supply powering the SDI device must also be connected to a common terminal on the control panel.

Do not connect the earth ground for the stand-alone power supply to Terminal 10 on the control panel.

12.3D9131A Parallel Printer Interface Module

The Bosch Security Systems, Inc. D9131A Parallel Printer Interface Module is a four-wire powered device used to connect a standard parallel printer to a control panel. D9412GV3 can supervise three printers and the D7412GV3 can supervise one printer. A separate D9131A Parallel Printer Interface Module is necessary for each printer. The D9131A connects to the printer using a standard parallel printer cable.

12.3.1 Switch Settings

Switches on the D9131A assign a unique address (17 to 19) for each printer. The address determines if the printer is supervised, the area scope of the printers, and the area to which the printer is assigned. Refer to Printer Parameters in the D9412GV3/D7412GV3 Program Entry Guide (P/N: F01U170807) for a complete description of addresses.

Table 22 shows the correct switch setting for each address.

Table 22: Printer Address Switch Settings

Printer	Switch
	1	2	3	42	5	6
17	ON	ON	ON	ON	ON	ON
18 1	OFF	ON	ON	ON	ON	ON
19 1	ON	OFF	ON	ON	ON	ON

12.3.2Supervision Supervision includes:

∙Proper operation of the SDI bus

∙Proper connection of the printer cable between the printer and the D9131A

∙Printer paper supply

∙Printer selected (on-line)

∙Printer power.

The control panel sends an SDI Failure Report to the receiver if communication with the printer interface fails. If an SDI failure occurs, SERVC PRINTER appears at the keypad. The report to the receiver includes the address of the troubled D9131A to indicate which printer needs service.

If an SDI device is supervised and Terminal SDI A becomes disconnected, the device can continue to operate normally, depending upon environmental conditions.
