11.2 Keypad Terminals 29 to 32
The Bosch Security Systems, Inc. keypad is a
four-wire powered device used to arm and disarm
areas, annunciate complete system status,
initiate system tests, and control many functions
of the security system.
The D9412GV4 or D7412GV4 systems can
supervise up to 16 keypads (D7212GV4 can
supervise up to 8 keypads). The control panel
sends a Serial Device Trouble Report, SDI
FAILURE, in the Modem IIIa
Module Failure (333) in Contact ID format, if it
loses communication with a supervised keypad.
CALL FOR SERVICE appears in any keypad that
loses communication with the control panel, if
the keypad has text display capability. SERVC
KEYPAD appears at all other keypads connected
to the system.
A total of 32 unsupervised keypads can be
connected to the system. The number of
supervised keypads, number of areas, and the
available power affect the total number of
keypads that can be connected to the system.
Refer to Keypad in the
D9412GV4/D7412GV4/D7212GV4 Program Entry
Guide (P/N: F01U170807) for complete
programming details on keypad options.
Five types of keypads are available for use with
the system.
