2.9 Fire Zone Wiring
4-Wire Smoke Detectors
All fire zones must be wired according to the following diagram:
2.10 24-Hr Auxiliary Input Wiring (PGM2)
If PGM2 has been programmed for 24-hour operation, the
zone must be wired according to the following diagram:
2.11 Keypad Zones
Each “z” keypad on the system has a zone input to which a
device - such as a door contact - can be connected. This
eliminates the need to run wires back to the control panel for
every device.
To install the keypad, open the keypad plastic by removing the
screw at the bottom of the unit. Locate the five terminals on
the keypad circuit board. Connect the four Keybus wires from
the control panel: the red wire to R, the black to B, the yellow
to Y and the green to G.
To connect the zone, run one wire to the Z terminal and the
other to B. For powered devices, use red and black to supply
power to the device. Run the red wire to the R (positive) termi-
nal and the black wire to the B (negative) terminal.
When using end of line supervision, connect the zone accord-
ing to one of the configurations outlined in section 2.8
“Zone
Wiring” on page 5. End of line resistors must be placed on the
device end of the loop, not at the keypad.

Assigning Keypad Zones
When using keypad zone inputs, each input used must be
assigned a zone number in Installer’s Programming.
First, ensure that you have enrolled all installed keypads into
the desired addresses. (See section 2.5
“Keypad Assign-
ment” on page 4.)
Next, enter programming section [020] to assign the zones.
There are eight programming locations in this section, one for
each keypad address. Enter a 2-digit zone number for each of
the keypad zones. This number must be entered in the loca-
tion corresponding to the keypad to which each zone is con-
nected.
([DPSOH
: The zone on an LCD5500Z keypad in address 8 is
to be assigned zone 3. In section [020], scroll to option [8]
and enter (03).
