Fire Zone Wiring; 24-Hr Auxiliary Input Wiring (Pgm2); Keypad Zones - DSC power608 Installation Manual

NOTE: This option should be selected if either Normally
Closed (NC) or Normally Open (NO) detection devices or con-
tacts are being used.
Double End of Line (DEOL) Resistors
Double End of Line resistors allow the panel to determine if the
zone is in alarm, tampered or faulted.
To enable panel detection of double end of line resistors, pro-
gramming section [013], option [1] must be OFF and option
[2] must be ON.
NOTE: If the Double EOL supervision option is enabled, all
hardwire zones on the main panel must be wired for Double
EOL resistors, except for Fire and 24 Hour Supervisory zones.
NOTE: Do not wire DEOL resistors on keypad zones.
NOTE: Do not use DEOL resistors for Fire zones or 24 Hour
Supervisory zones. Do not wire Fire zones to keypad zone ter-
minals if the DEOL supervision option is selected.
NOTE: This option can only be selected if Normally Closed
(NC) detection devices or contacts are being used.
NOTE: Only one NC contact can be connected to each zone.
Wiring multiple detection devices or contacts on a single loop
is not allowed.
The following chart shows zone status under certain condi-
tions:
Loop Resistance
0Ω (shorted wire, loop shorted)
5600Ω (contact closed)
Infinite (broken wire, loop open)
11200Ω (contact open)

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.
NOTE: Keypad zones do not support DEOL resistors.

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 5.)
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.
Example: 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).
NOTE: Keypad zones 1-6 will replace zone terminals Z1-Z6 on
the control panel.
NOTE: Once the keypad zones are assigned, you must also
program zone definitions and zone attributes. (See also sec-
tion 5.4 "Assigning Keypad Zones" on page 16.)
