ZONE TAMPER DISABLED ZONE TAMPER ENABLED
When Zone Tamper is enabled, the zones are sealed with
two 4K7 resistors which allow monitoring of both
Alarm and Tamper on each zone input over 4 wires.
Zone Tamper looks for these resistances:
When Zone Tamper is enabled, (P34E 6E = off), then
all zones must be wired as shown above, otherwise zone
alarms will be interpreted as tamper alarms.
ZONE SEALED: 2K2
ZONE ALARM: 4K7
TAMPER ALARM: OPEN CIRCUIT
NOTE:
P34E 6E is ON P34E 6E is OFF

8NESS D24 CONTROL PANEL - INSTALLATION & PROGRAMMING MANUAL
ZONE INPUTS 1–24
The Ness D24 has 24 End Of Line monitored zone inputs. Each zone input must
be terminated with a 2K2 (2200 ohm) End Of Line (EOL) resistor as supplied.
If Zone Tamper is enabled (P34E 6E off), the zones are sealed with two 4K7
resistors which allows monitoring of Alarm and Tamper states over 4 wires for
each input.
The zone input can be individually programmed for various alarm types including
Instant, Delayed, 24hr, Area, Monitor, Fire.
All inputs must be sealed with an EOL resistor even if unused.
For wiring details of Keypads, Keyswitches, Panic Buttons and Warning devices,
see the wiring diagrams in the wiring section of this manual.
TAMP - Tamper Input
The TAMP input must also be sealed with a 2K2 end of line resistor. This input is
always a 24hr input.
KEY - Keyswitch Input
This a 24hr Panic input or an optional keyswitch input for Arming/Disarming.
NOTE: By default, the KEY input is a Panic input. To use the KEY input as a
keyswitch input, program P400E 1E, (this maps the input to Output Group zero,
which disables it as a zone).
17 V AC TERMINALS
These terminals are for the connection of the Ness plug-pack. The Ness D24
requires an AC transformer rating of 1.4 Amps @ 17V AC minimum. (Ness Part
No. POW215)
EARTH
For maximum protection against damage caused by lightning strikes, connect a
good earth to this terminal. Alternatively use the Earth lead from the plug pack.
BATTERY
These terminals are for the connection of a sealed lead-acid rechargeable 12Volt
battery. Charge current is limited to 350mA. The charge voltage is factory preset
at 13.8V. A 12 Volt sealed lead acid rechargeable battery must be connected for
correct panel operation. Observe correct polarity when connecting the battery.
(Ness Part No: BAT210, 12V 7Ah battery)
J1 TAMPER - Internal Tamper Input & Program Link
The J1 link has two purposes:
1. To enter Installer Program Mode on initial power up. Power up with the J1
link OFF.
The J1 link must be ON in operating mode. (Or, if using J1 for housing tamper,
the tamper switch/es must be sealed).
2. Housing Tamper. When used with the Internal Tamper Lead (supplied), J1
serves as the 24hr tamper input for the panel’s internal tamper switch.
Replace the J1 link with the Internal Tamper Lead and tamper switches.
An EOL resistor is NOT required on this input.
When J1 is used for internal tamper, powering up with the panel’s lid open will
enter Installer Program Mode.
INPUTS
INSTALLERS’ TIP
Testing Zone Inputs - when
troubleshooting your zone wiring, the
voltages across the zone input can
help determine the wiring fault.
Correct zone voltages as follows:
WITHOUT ZONE TAMPER
(FACTORY DEFAULT)
One 2K2 resistor per input
Zone is Sealed: 4V ±0.4V
Zone is short circuit: 0V
Zone is Open circuit: 8V ±0.4V
WITH ZONE TAMPER
2 x 4K7 resistors per input
providing zone alarm and zone
tamper
Zone is Sealed: 4V ±0.4V
Zone is Unsealed: 5.4V ±0.4V
Zone is short circuit: 0V
Zone is Open circuit: 8V ±0.4V
Zone tamper is available in D24
V1.5 and later.

Up to 3 LCD keypads can be connected to the D24.
CABLE LENGTH
The maximum allowable cable length is 100m (total cable length to all keypads).
Use at least 14/020 stranded cable or heavier.
The keypad/s may not work correctly if the cable runs to the keypad/s are too long or the
cable used is too thin. A 2k2 resistor added across DATA & +12 at the control panel may
improve keypad data comms in such cases. We stress the importance of heavy cable to
the keypads and you should run extra pairs to double up for power if required.
DISPLAY TEST
To display all the keypad icons press and hold the button for at least 2 seconds. All
the icons will be on whilst the button is held down.
The display test can be activated at any time either in operating mode or any program
mode.
