3.9 Option Bus Wiring
See Figure 9. Used for options such as the DS7416i
Communications Module, the DS7420i Dual Phone
Line Module, and so on. Also for Keypads 11 to 15.
For Commercial Fire Mode, Option Bus wiring should
be in conduit if run outside the enclosure.

3.10 Hardware Layout Example
See Figure 10.
• Up to 15 keypads can be used. Keypads 1 to 10
connect to the Keypad Bus and Keypads 11 to 15
connect to the Option Bus. One keypad must be
designated as Keypad 1 and connected to the
Keypad Bus. See the DS7447E/DS7447V2,
DS7445i/DS7445V2, and DS7448 Installation
Instructions for further details.
• A DS7420i (Dual Phone Line/Bell Supervision
Module) can be connected to the control panel,
and placed within the enclosure. Connect to the
Options Bus of the control panel. See the
appropriate keypad Installation Instructions for
further details.
• Up to two DX3010 Octal Relay Modules can be
connected to the control panel and placed within
the enclosure. Connect to the Option Bus of the
control panel. This provides an additional 8 Form
“C” relay outputs for the Control Panel. See the
DX3010 Installation Instructions for further details.
• A DS7430 or a DS7436 (Multiplex Expansion
Module) can be connected to the control panel
using the expansion port. This allows for the
connection of additional zones using the Option
Bus. See the DS7430 or DS7436 Installation
Instructions for further details.
• Up to 30 DS7432E 8-Input Remote Modules can
be connected to the DS7430 or DS7436. Connect
to the Power and Bus Terminals of the Multiplex
Expansion Module. This allows for a means of
addressing up to 240 input loops of conventional
contacts to the control panel. See the DS7432E
Installation Instructions for further details.
