Commercial Fire Applications

The DS7447E keypad can be used in commercial fire

applications with the DS7400Xi Control Panels as

follows:

• Single Keypad Use in Commercial Fire Systems: The

keypad must be used on the keypad bus and must be

assigned as Keypad Address 1. It can be mounted on

the front of the control panel enclosure. If it is not

mounted on the front of the control panel enclosure,

you must mount it in the same room as and within

6 m (20 ft) of the control panel, and run the wire in

conduit or provide equivalent protection against

mechanical damage.

• Multiple Keypad Use in Commercial Fire Systems: One

keypad must be used on the keypad bus and must be

assigned as Keypad Address 1. It can be mounted on

the front of the control panel enclosure. If it is not

mounted on the front of the control panel enclosure,

you must mount it in the same room as and within

6 m (20 ft) of the control panel, and run the wire in

conduit or provide equivalent protection against

mechanical damage.

Connect keypads 2 through 10 to the keypad bus and

place as needed within the wiring limits.

Use only one keypad on the option bus and assign it

as keypad address 11, 12, 13, or 14.

Notice

Keypad 15 is not available on commercial fire

systems because Option Bus Address 15 is used

for the DS7420i Dual Phone Line/Bell Supervision

Module.

Notice

On the DS7400Xi Control Panels, up to 11

keypads can be used in commercial fire mode.

Install one keypad on the option bus and up to ten

keypads on the keypad bus.

Notice

When using multiple keypads in a commercial fire

application, a UL Listed auxiliary power supply

might be required.
