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 enclosure. If it is not mounted on
the front of the control enclosure, you must mount it in
the same room as and within 6 m (20 ft) of the control
equipment, 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.
Note 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.
Note 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.
Note When using multiple keypads in a commercial
fire application, a UL Listed auxiliary power
supply might be required.
