Sw4 in UL installations. Use the plug
(provided) for UL installations to fill the dip switch
opening; press the plug in until it is below the
surface of the keypad cover.
NOTE:
Reversing the DAT1 and DAT2 wires will cause all
keypads in the system to malfunction. Reversing
the power wires will damage the keypad.
Note the guide channels on the back, for running
the wire to surface conduit at the top or bottom of
the keypad. The keypads may also be semi-flush
mounted into a wall (requires a kit, Model 8330) or
set on a desk using the mounting bracket as a
foot to tip the top forward.
The maximum run of 22 gauge wire (one keypad
per wire run) is 300 feet to the Display Control
keypad, and Control keypad (see Wiring Data
step
#5, near the beginning of this chapter). It is
possible to make longer runs for the keypads
(non-UL only). Call the
800- number for assis-
tance.
Data: Power requirements are 9-15VDC,
nominal = 70ma (50ma while CCU is on battery);
alarm = 120 (100 on battery) ma plus 50 ma for
the keypad’s alarm sounder.
