INTRODUCTION

CONGRATULATIONS for selecting Linear's DUAL 824
Security System. The Model DUAL 824P Control Panel and
the Model DUAL 824KP Keypad incorporate many advanced
and sophisticated features. The system can be expanded
and customized to fi t the installation's specifi c needs.
The DUAL 824P Control Panel and its accessories are
designed and manufactured by the oldest wireless security
company in North America. You can look ahead to many
years of reliable service with this Control Panel and its
accessories.
Many insurance companies offer discounts on homeowners and
renters policies when a security system is installed. Discount
credits vary with different companies and generally increase in
savings with an increase in the level of protection. Inform the
user to ask their insurance agent about savings available.
The DUAL 824P Control Panel is UL Listed. For a UL smoke
alarm system, there must be at least one smoke detector
programmed into the Control Panel to meet National Fire
Protection Association (NFPA) Rule 72 Chapter 2 and UL
217 requirements. Many insurance companies require these
conditions to be met to qualify for a discount. Only use the
Model DXS-73 smoke detector with this Control Panel for a
UL smoke alarm system.

NOTE: Some cities and municipalities may require an
alarm system permit. Check with the local authorities
before installing this system.

CONTROL PANEL

The DUAL 824P Control Panel is the heart of the system.
It monitors all of the system's wireless sensors, hardwired
loops, and controls the alarm sirens and Model DUAL 824KP
hardwired keypads.
The Control Panel constantly monitors the condition of the
system's sensors and hardwired contacts, displaying which
protected doors and windows are open or closed. If an
alarm occurs, the keypads display which sensor(s) caused
it. When a sensor has a low battery, the keypads display
which sensor needs a new battery. Sensors that send hourly
status transmissions keep the Control Panel informed of their
operating condition.
Up to eight different custom user codes can be used to
operate the system. For security, a user code must be
entered to disarm (turn off) the system. The system can be
armed (turned on) by entering a user code, or with the unique
“Quick Arm” feature. The fi ve restricted user codes and the
special page alert user code can only arm and disarm the
system, no programming changes (except changing user
and duress codes) are allowed. The master user code is
allowed to program the Control Panel, and a duress code
can be selected for emergency disarming of the system with
a duress report to the Central Station. The page alert user
code can dial a pager number to inform the pager wearer
when the system is disarmed.
The Control Panel's memory will retain the user codes and
all of the system's programming, even during a total power
loss. An optional backup battery can be installed to power the
system during short power failures.
The built-in digital communicator connects the Control Panel
to a Central Alarm Monitoring Station through the telephone.
With a monitored system, the central station can dispatch
authorities in case of burglary, fi re or other emergency. The
central station can also call family, friends, neighbors, or
anyone else designated on a custom call list. System arming
(closing) and disarming (opening) reports by user can also
be sent.
Each sensor can report directly to the Central Station using
the digital communicator's Point ID feature. If a sensor triggers
an alarm or experiences supervisory trouble, a unique report
code can be sent for immediate identifi cation of the event.

REMOTES †

The optional Model VB-2 digital voice response module can
be installed in the Control Panel. The VB-2 module provides
three exciting features: 2-way audio monitoring capability at
the Central Station through the communicator, local voice
prompts from the keypad's speaker (with Model RSM-2
speaker/microphone kit installed), and voice prompted
remote system control using in-house or off-site pushbutton
telephones.
The system has 24-hour capabilities that are always ready
to operate, even when the system is disarmed. They can be
triggered by buttons on the hardwired keypads, a wireless
keypad, portable remote controls, carbon monoxide detectors,
and smoke detectors. Pressing the EMERGENCY or FIRE button
for two seconds will cause an immediate siren and call the
central station. IMPORTANT: For personal emergency use

only. Not for use as a UL Listed Medical Alert System.

The Control Panel's Environmental feature is active 24-hours
and can be triggered with sensors connected to devices such
as water fl ow detectors, over/under temperature sensors, fl ood
sensors, etc. The Environmental feature activates the chime
annunciator without sounding the siren. The Environmental
feature does not send communicator reports.
An Automation Output in the Control Panel provides an
easy way to connect external devices to the Control Panel.
The output is fully programmable to activate on a variety
of conditions, such as when the system is armed, during
alarms, and during exit/entry delays. The Automation Output
can connect to lighting control modules, relays, noisemakers,
and indicators. The Control Panel's and wireless keypad's

key and any system sensors can control the Automation
Output.
The Control Panel can be programmed locally using its own
keypad or remotely, over the telephone, using Linear's Model
RA-2400 Remote Access software program. The RA-2400
upload/download program is a Windows™ application that
runs on a personal computer and communicates with the
Control Panel through a modem, connected directly to the
panel, or through the telephone line.

DOOR/WINDOW SENSORS

The DXS-31 and DXS-32 sensors monitor doors and windows. They
send radio signals to the Control Panel. One type of signal is sent
when the door or window is opened, and a different type of signal is
sent when the door or window is closed. If the system is armed, a
sensor can trigger the Control Panel's burglary siren when its door
or window is opened. Both sensors are supervised, send hourly
status reports, and monitor their battery condition.

DXS-31

DXS-32

WIRELESS KEYPAD

The DXS-10 wireless keypad is used to operate the system remotely.
It can be placed in a convenient spot so the user doesn't have to
go to the hardwired keypad to operate the system. The wireless
keypad can also trigger the emergency or fi re siren and actuate the

Automation Output. Pressing

will cause the hardwired keypad(s)
to sound Beeps corresponding to the current
operating mode. The DXS-10 is supervised,
it sends hourly status reports and monitors
its battery condition. IMPORTANT: For

personal emergency use only. Not for use
as a UL Listed Medical Alert System.

DXS-10

SMOKE DETECTOR

The DXS-73 is a high quality smoke detector with a built-in radio
transmitter. As soon as smoke is detected, the unit will sound its local
noisemaker. Then, 20 seconds after the local noisemaker sounds,
the transmitter sends an alarm signal to the Control Panel. The alarm
signal will be repeated every 20 seconds as long
as smoke is still present. A restoral signal will be
sent when the smoke detection chamber clears.
The DXS-73 is supervised, it sends hourly status
reports, and monitors its battery condition.

NOTE: A Model DXS-73 Smoke Detector is required to

create a UL Listed smoke alarm system. See Page 26 for
details on adding a smoke detector sensor to the system.

REMOTE CONTROLS

The DXT-41, DXT-61 single-button and DXT-23, DXT-42 multi-button
remote controls can be used to remotely arm and disarm the system.
The DXT-42’s left button will arm and the right button will disarm
the system. Pressing both buttons simultaneously will trigger the
emergency siren. Alternately the Control Panel can be programmed
to respond to the DXT-42 by arming and disarming with the left
button, and activating the automation output with the right button.
These transmitters can also be programmed to activate various
other Control Panel zones. These transmitters are not supervised.

The DXS-81 bill trap can be used with the Control Panel in non­UL small commercial hold-up installations. The unit is concealed in
a cash drawer under a stack of currency, with a single “bait” bill
secured in its money clip. During a hold-up, the cashier removes
the stack of currency along with the “bait” bill. When a “bait” bill is
removed, the transmitter sends a signal to the Control Panel. Four
additional signals are sent within the fi rst minute
after the “bait” bill is removed. When the “bait” bill
is replaced, a restore signal is sent. The DXS-81
is supervised, it can send hourly status reports
(optional) and monitors its battery condition.

DXS-81‡

PASSIVE INFRARED MOTION DETECTOR

The DXS-54 is a passive infrared (PIR) motion detector with a built-in
radio transmitter. The PIR detects motion in its detection pattern by
measuring the infrared emission levels of objects that it “sees”. If
the infrared levels change quickly, as when a person moves across
the detection pattern, the PIR will recognize the
change as an intrusion and send an alarm signal
to the Control Panel. An alarm will be triggered if
the system is in the Away Mode. The DXS-54 is
supervised, it sends hourly status reports and
monitors its battery condition.

DXS-54

DXT-61‡

ABOUT SENSOR STATUS SUPERVISION

All DXS Format sensors transmit hourly status reports. All DXT
Format sensors do not transmit hourly status reports. Both sensor
formats can be used with the system.
When a sensor is programmed into the Control Panel, the system
will set the sensor as non-supervised or supervised. Sensors set
as non-supervised are not expected to send hourly status reports.
Sensors set as supervised are expected to send hourly status
reports. If a status report is not received in 8 hours from a sensor
set as supervised, the RADIO indicator will fl ash.
When sensors are programmed into the Control Panel, ALL

STATIONARY SENSORS ARE SET AS SUPERVISED, ALL
PORTABLE SENSORS ARE SET AS NON-SUPERVISED.

If stationary DXT Format sensors have been programmed into the
Control Panel, be sure to change their setting to non-supervised
to prevent RADIO indications. This will not prevent low battery
monitoring.
If portable DXS Format sensors have been programmed into the
Control Panel, and the installation requires supervision for specifi c
portable sensor(s), change the selected portable sensors setting to
supervised.
After programming the sensors, if changes are required, refer to
“Changing a Sensors Supervision” on Page 30 for details on
changing the way a sensor’s supervision is set.

HARDWIRED LOOP WIRING

✦ The DUAL 824 supports up to eight normally

open/closed hardwired loops each with 2.2K
end-of-line resistor supervision.

✦ Each hardwired loop that is wired and

programmed uses one sensor location.

✦ Each hardwired loop can be programmed to any

sensor number.

✦ Each hardwired loop can be programmed as any

sensor type, including arm/disarm toggle.

✦ Four COM terminals are shared as loop returns

for the eight loops.

✦ Each hardwired loop has a 400 millisecond

response time.

✎ NOTE: For UL installations, use UL Listed cable for

all hardwired loop wiring.

1. Route wiring from the Control Panel to each
hardwired switch contact, sensor, or device.
Route the wires through the wiring slot or
through a knockout for conduit wiring.

✎ NOTE: Maximum recommended hardwired loop

length is 500 feet (250' out, and 250' back) for each
loop. Maximum loop resistance (excluding the EOL
resistor) is 100 ohms.

2. Connect the loop wires to LOOP # and COM
terminals. For powered devices connect power
wires to +12 VDC and any COM terminal.

3. On the sensor end, connect each normally
closed sensor in series with the loop wires.
Connect each normally open sensor in parallel
with the loop wires. See wiring fi gure.

4. After the last sensor on the loop, connect a 2.2K
end-of-line resistor across the loop.

✎ NOTE: Before the hardwired loops will function,

they will need to be programmed. This will be
covered in the Basic Control Panel Programming
section of this manual.

line if the system is monitored, requires 2-way
audio, telephone remote command, or for remote
programming with RA-2400 software.

✦ Telephone RING & TIP terminals are for

connection to the incoming telephone line.

✦ Seized telephone ring & tip (R1 & T1) are for

connection to local telephone sets. When the
communicator activates, all the local telephone
sets will be disconnected to prevent an off-hook
telephone on the premises from blocking the
communicator call.

1. Install a USOC RJ31-X or RJ38-X jack to the
telephone system near the Control Panel.

2. Route an appropriate modular telephone line
cord from the jack to the Control Panel.

3. Route the line cord through the Control Panel's
wiring access slot or through a knockout for
conduit wiring.

4. Connect the incoming telephone line wires to the
Control Panel's telephone terminal block TIP and

RING terminals.

5. Connect the local telephone set wires to the Control
Panel's telephone terminal block T1 and R1 terminals.

✦ When directly connecting (without a telephone line)

to the DUAL 824 with the RA-2400 remote access
software (Version 1.3 or later), disconnect the
incoming telephone line and connect the modem
to the panel's TIP and RING terminals (with the
modem's red & green phone line wires). Press the
EMERGENCY key while in Test Mode to cause the
panel to connect to the modem.
