ICP-SDI-9114 | Installation Instructions | 1.0 Introduction
1.0 Introduction
The ICP-SDI-9114 SDI Splitter is an accessory to the B9512G, B8512G, D9412GV4, D7412GV4, D7212GV4,
D9412GV3, D7412GV3, D7212GV3, D9412GV2, D7412GV2, D7212GV2, D9412G, D7412G, D7212G, and D9124
control panels. The SDI splitter provides the ability to set up two independent SDI buses from a single SDI
connection on the control panel. When this accessory is installed with a control panel and wired to create
separate SDI buses for fire and intrusion devices the system is a UL 864 compliant combination control panel.
The ICP-SDI-9114 is not for use with SDI2.
The D7212GV4/D7212GV3/D7212GV2/
D7212G Control Panels are not rated for
The SDI splitter has three sets of four-position SDI terminals: PANEL, FIRE, and BURG. The PANEL terminals are
used for the SDI connection to the control panel. The terminals labeled FIRE and BURG are handled equally, and
either terminal can be assigned to any collection of devices that require two separate buses. The SDI splitter
does not affect the operation of the control panel or the associated SDI devices.
Commercial Fire.
2.0 Mounting
UL requires that the SDI splitter be mounted in the same enclosure with the control panel, or in a
separate enclosure in the same room within 20 ft (6.1 m) of the control panel and connected by
conduit.
The enclosures for the GV3/GV2/G Series Control Panels have four module mounting locations. Refer to Figure 1.

3.0 Installation
The SDI splitter operates on power from the control panel, but the DC current is limited to 550 mA for each bus
(FIRE and BURG), or enough power for two D1255 or two D1260 keypads. A total of up to 32 SDI devices can
connect to the output buses. A fault to the power or data connections of one bus does not affect the other bus.
An external power supply, connected with a common ground, is required to provide power for
devices that exceed the 550 mA limit. Refer to Figure 3 and Figure 4 for wiring when an external
power supply is used. To determine the current usage for SDI devices, use the Current Rating Chart
for Standby Battery Calculations in the B9512G/B8512G Installation and System Reference Guide
(P/N:F01U303996), D9412GV4/D7412GV4 Installation and System Reference Guide (P/N:
F01U265457), D9412GV3/D7412GV3 Approved Applications Compliance Guide (P/N: F01U143069) or
in the D9412GV2/D7412GV2 Approved Applications Compliance Guide (P/N: F01U003639).
Figure 2 shows the wiring for one SDI splitter with two SDI devices connected to each bus, where the DC current
drawn on each bus does not exceed 550 mA.

* Important: When the ICP-SDI-9114 SDI Splitter is used in a UL864 or NFPA72 installation, you can install only
one keypad on the Fire bus. Program this keypad as “Master” for Fire.
Figure 3 on page 6 and Figure 4 on page 7 show how to use an external power supply to isolate the
power connections between buses.
Figure 3 shows two approved methods of wiring when more than two SDI devices are installed on
one of the buses, and the DC current drawn on one of the buses exceeds 550 mA.
A maximum of two SDI splitters can be used with one control panel to increase the number of
isolated SDI buses to four. The SDI power connection on the control panel supports any two
isolated buses. A separate external power supply is necessary for each additional bus over two.
Figure 4 shows the correct wiring when two SDI splitters are connected to one control panel.

4.0 Operation
The SDI splitter has three green LEDs that monitor bus activity. The LEDs are labeled PANEL ACTIVE, FIRE
ACTIVE, and BURG ACTIVE. During the powering up process, all LEDs flash briefly to indicate that power is
applied and the device is operating. During operation, the LEDs flash randomly to indicate active non-faulted
buses. If an LED does not show activity, the corresponding bus is faulted, is not in use, or has only unsupervised
devices connected to it.
