AMPS:Acronym for Advanced Mobile Phone System, which is the existing analog mobile phone
system used for cellular communication in North America.
A Side / B-Side: The FCC has divided the spectrum allocated to cellular communication between two
carriers in each geographic location: A and B. The “B” side is operated by the local
telephone company (known as wireline), while the “A” side is run by a competitor
(known as non-wireline).
Cell: The equipment, including antennas, RF transmitters, RF receivers, that is used to
establish and route communications between a mobile cellular radio and its intended end
point.
Control Channel: Any one of several dedicated RF channels that are used by a cellular radio to register its
MIN with a local cell and to periodically check in with that cell. The control channel is
also used by the radio to “dial” a phone number through the cell. Additionally, control
channels are used by the cell to “ring” a mobile cellular radio.
MIN: Acronym for Mobile Identification Number, which is a cellular radio’s unique, 10-digit
“phone number.”
SS7: Acronym for Signaling System Seven, which is the network that is used by all telephone
companies for dialing and establishing all cellular and land-line phone calls.
Voice Channel: Any one of many dedicated RF channels used for transmitting and receiving audio data
between a mobile phone and a cell. (Not used with the K3852.)

Introduction
The K3852 is the subscriber end of the AlarmNet C reporting system. It is comparable to a digital
communicator, but instead of transmitting signals over the telephone lines, it transmits radio signals to the
central monitoring station using the control channel of the AMPS cellular phone network. This allows
faster and more secure reporting and greater coverage.
The K3852 is compatible with existing installations using ADEMCO equipment or other control panels. It
can be used in conjunction with digital communicators on the same system to provide redundant reporting.
The K3852 Transceiver uses the control channel of the Advanced Mobile Phone System (AMPS) cellular
network to report subscriber alarms and system status messages. It operates on either the “A” or “B” side
of the cellular network without using a voice channel. Because alarms are transmitted only on the control
channel, a true “phone call” is never placed. This eliminates delays due to busy or saturated cells where no
voice channels are available.
The K3852 is compliant with the MicroBurst standard for packet-based control channel cellular
communication. Alarm and status packets are transmitted from the subscriber to a local cell where they are
identified and then routed using SS7 to the AlarmNet Control Center. The AlarmNet Control Center then
logs the alarm and routes it via RF to the appropriate AlarmNet-A or AlarmNet-M equipped central station.

Section 3: Installation and Setup
Removing the Lower Cover
During normal operation, the lower cover of the K3852 should
remain in place.
To remove the cover, gently press in on either of the two
locking tabs and lift the cover.
Removing the cover will trigger the following two events:
1. A tamper zone alarm will be transmitted.
2. The RSSI bar graph, which is intended to be used as an
installation tool and troubleshooting aid, will become
active.
Do not attempt to remove the upper cover. There are no user serviceable components
!
beneath this cover.
Refer to the following diagram to identify the components of the K3852.

K3852 Initial Power-Up Sequence
Before connecting power, check that the following have been completed:
q 16.5VAC / 40VA transformer connected to terminal block positions 1 & 2
q P2 in the correct position for zone 1 & 2 trigger levels (zone mode only)
q P3 in the correct position for zone or ECP operation
q Antenna installed
Apply power by plugging in the 16.5VAC / 40VA transformer. If using the optional battery, plug it into
the battery jack. Initially, all K3852 programming options are set to the factory default settings.
Upon applying power, the K3852 enters the power-on reset mode, indicated by all 8 LEDs being solidly lit
for approximately 5 seconds followed by the RSSI bar graph green LEDs lighting in a “chaser” sequence
from left to right. After this power-up sequence, the Radio Status LEDs display solid green, blinking
yellow, and solid red.
This indicates the K3852 is functioning but not yet initialized. The K3852 then begins its initialization
sequence. During this process, the K3852 is verifying its Mobile Identification Number (MIN) and
checking for MicroBurst service on both the “A” and “B” side carriers. This initialization is displayed on
the RSSI bar graph as follows (refer to Table 1): The yellow LED will remain unlit and the green LED at
the extreme right of the display will begin to blink. This green LED then lights solid (after a short period
of time), and the next green LED to the left begins to blink. When this LED lights solid, the next green
LED begins to blink, and so on, until all 4 green LEDs are lit solid. This countdown event may take up to 3
minutes to complete.
Once this sequence has been completed, the RSSI display begins to function as a signal strength indicator
as described in Selecting a Radio Installation Site section. The radio is now in normal, unprogrammed and
unregistered operation. If radio setup and self-test fails, LED 5 will blink continuously and no further
progress will be made. If MicroBurst coverage is not found on either the A or the B side, the K3852 will
repeat steps 2 and 3. These steps will be repeated until MicroBurst is found.

Selecting a Radio Installation Site
The K3852 is designed to be mounted on a vertical surface (wall), with the included antenna pointing up.
When selecting mounting a site, maintain distances from various types of electrical equipment as listed in
Table 2. Additionally, observe the maximum wire run lengths (see Table 4).
The K3852 is intended for indoor installation only. Mounting outdoors will cause system failure and
may present a shock hazard.
1. Remove the cover and install a fully charged battery. If a fully charged battery is not available, you can
connect a 16.5VAC / 40VA transformer.
During battery operation, removal of the lower cover will significantly reduce the life of the charge on
the battery. To get the maximum backup battery life in the event of an AC loss, the lower cover must
be replaced when the installation is complete. (Note that the signal strength bar graph located below
this cover is only needed during installation.)
2.Select a likely location by monitoring the signal strength bar graph. Refer to the Using an Unregistered
K3852 as an Installation Tool paragraph below. A strong signal lights more LEDs than a weak signal.
3. Find a location where the signal level is consistently better than 1-½ bars or –101dBm as measured
with the 7720P. The K3852 can function properly with the signal strength level as low as one-half bar
(yellow blinking), but this may be an indication of marginal coverage.
Notes:
1.Optimum RF performance can usually be found at the highest point within a building, with the fewest
number of walls between the radio and the outside of the premises.
2.Avoid mounting the antenna near other electronic devices. Table 2 provides minimum distances.
Highest RF energy is in the direct, horizontal line of the antenna. Therefore, vertical separation
(moving electronic devices either higher or lower on the wall) provides a higher level of isolation from
the radio.

Using an Unregistered K3852 as an Installation Tool
An unregistered K3852 will display signal strength once the initial

Testing the Installation
Using an Unregistered K3852 to Test the Installation
An unregistered K3852 can send three types of test messages: unvalidated, validated, and test registration.
Refer to the table below.
Unvalidated Test Message
Use this to test the path from the K3852 to the cell.
SINGLE click the tamper switch to send a test message
to the local cell. The RSSI bar graph displays how well the
K3852 is receiving this cell. Read the RSSI display from
left to right: If the yellow and the next two green LEDs are
illuminated, the display is read as “three bars.” If the
yellow and the next two green LEDs are lit solid with the
following green LED flashing, the display is read as “three
and a half bars.” This is a stronger received signal than the
previous example. Refer to the Full Scale RSSI Display
diagram on the previous page.

Section 4: Programming the K3852
There are 3 methods of programming the K3852: (1) Using a 7720P Programming Tool; (2) using an ECP
capable control panel that supports long range radio programming,; (3) using the Programmerless
Registration Option (PRO).
To use the 7720P, connect the 7720P then power-up the radio. Refer to the description below.
To use an ECP capable control, connect the control, then power-up the radio. Select ECP operation by
pressing the tamper switch once while the radio status LEDs are flashing in unison, which toggles the
default configuration from zone mode to ECP mode. The unprogrammed K3852 flashes the radio status
LEDs as follows during initial power-up:
ECP mode = twice per second
Zone mode = once per second
The default device address of the radio is 3. Refer to the control’s instructions for programming procedures.
To use the Programmerless Registration Option, power-up the radio, then contact AlarmNet Technical
Assistance Center (TAC). Refer to the Programmerless Registration Option Installation and Programming
Guide insert.
Using a 7720P Programming Tool
The 7720P Programming Tool is powered by the K3852 via the Programming Jack. The K3852 will
automatically sense the presence of the 7720P when it is plugged in.
Each key of the 7720P has two possible functions: a normal function and a SHIFT function. To perform a
normal key function, simply press the desired key. To perform a SHIFT key function, press the SHIFT key,

Enter programming mode by pressing [ENTER] during the initial power-up period after the chaser
sequence (while radio status LEDs are flashing consecutively or in unison).
The K3852 reads its EEROM to determine its preprogrammed parameters. A CRC of the EEROM
locations is also read. If the computed CRC does not match the one read from EEROM, or if the
programming parameters are invalid, the 7720P LCD displays "NO PROG" and the radio status LEDs flash
in unison (after the initial chaser sequence). Otherwise, the LEDs flash consecutively.

Section 5: Registration
Test Registration
Prior to registering the radio, a test registration can be sent. The test registration is used to confirm the
programming of the radio and the routing across the AlarmNet C network without actually registering the
radio. This feature requires a 7720P.
To initiate a test registration, first complete Quick Start programming. Options 2, 3, and 4 must be
programmed. After this, press shift-“T” on a connected 7720P. Test registration progress messages will be
displayed on the 7720P as described in the Interactive Registration paragraph below. When a test
registration has been completed, the radio will be reported to the central station as 5555 5555 9. This
indicates that the radio is programmed and routed correctly, but is not registered. If test registration fails, a
message on the 7720P will indicate the failure.
Registering the Radio
Once you have initialized and programmed the K3852, you must register it with AlarmNet Control. An
unregistered K3852 is indicated on the radio status LEDs as: solid green, blinking yellow, and unlit red.
The registration process consists of transmitting 3 messages in succession and receiving a registration
validation from AlarmNet Control. It can take several minutes to complete.
Initiate the registration sequence by either clicking the tamper switch 3 times or by pressing shift and the up
arrow [↑] on the 7720P. If you are using a 7720P, skip to the Interactive Registration section.
You can monitor the registration process on the RSSI display as follows: yellow LED will be blinking and
the green LED at the extreme right of the display will blink. When this green LED lights solid, the next
green LED to the left begins to blink. When this LED lights solid, the next green LED begins to blink, and
so on, until all 4 green LEDs are lit solid.
Once you have successfully completed the registration, the radio will enter normal operating mode; the
green radio status LED extinguishes, the yellow radio status LED continues normal blinking, and the RSSI
display indicates received signal strength.
If registration is not validated within 90 seconds, the K3852 will time out and all 5 RSSI LEDs will blink in
unison for 30 seconds. If repeated registration attempts time out, select a new installation site.
If the K3852 has been programmed with an invalid ID, city, or central station number, the registration will
be rejected. The right green LED will blink alternately with the remaining 4 RSSI LEDs.

Mounting
Section 6: Mounting and Wiring
Install the included “rubber duck” antenna by screwing it onto the connector that extends from the top of
the K3852. The final mounting site should be chosen so that:
• the wire lengths do not exceed the maximum wire lengths as specified in Table 4
• the minimum distance to other electrical devices is maintained
• the minimum signal strength level is observed
• there is access to the 7720P programming port & tamper switch
• all LED displays can be observed
• the antenna is free from any interference
Once the K3852 has been installed, programmed, and tested, anchor the radio permanently to the wall using
the screws included with the radio. Use the 3 mounting holes as shown in Figure 2. All 3 mounting holes
must be used. It is important to attach the unit securely so that it cannot be removed or accidentally
knocked off the wall after installation.
Wiring the K3852
Observe the wire length/gauge limitations for all input zone, radio fault and power connections as listed in
Table 4.
Zone Options
For zone operation, set the jumper on P3 for Z5 and Z6 as shown in Figure 5.
There are a total of 6 input zones available on the K3852.
• Zones 1 and 2 are selectable for either a (+V) or (GND) trigger with jumper P2.
• Zones 3, 4, 5 and 6 are set up strictly for a (+V) trigger. A positive voltage applied to these zones will
trigger an alarm. For added flexibility, each zone may be programmed individually to "invert" its input
so that a positive voltage is removed from the zone input to trigger an alarm.

Other zone options include:
• Telco fault input (triggered when the phone line to the control panel loses voltage).
• Open/Close reporting (triggered when the user arms and disarms the alarm control panel). An additional
monthly charge is applicable to this service.
• Steady or pulsing on input.
If using zone mode, run a wire for each input zone. A single common ground between the radio and control
is also required. The alarm and power wires must be routed through the back of the K3852. The ground
wire should be run from the alarm panel. The wire access port is located between the terminal block and the
battery on the back cover. Refer to Figure 3 for terminal block positions. Refer to the following wiring
diagrams corresponding to the installation’s configuration.
.
Figure 3. K3852 Terminal Block
Figure 4. K3852 P2 Jumper Configuration
Figure 5. K3852 P3 Jumper Configuration
Wiring and Configuring for Zone Operation
To trip a zone on the K3852, the triggering voltage from the control must be within 4.5V-14.2V. Trigger
levels above this range may cause permanent damage to the unit. Trigger levels below this range will result
in unreliable operation.
– 22 –
Page 23
If using zone mode, connect a wire from the triggering source (bell output, voltage trigger, etc.) to each
zone on the radio to be used. Examples of zone connections are shown in Figures 6, 7 and 8.

(+) Bell Output voltage ground triggered bell output
Figure 8. Wiring the K3852 zone inputs to voltage triggers, which generate
(+) voltage on each wire for different alarm conditions
NOTE: Trig (–) must be connected to the control’s electrical ground as shown in figures 6, 7, 8 9, and 10,
and not to earth ground.
If the alarm control panel is activating an output relay that will be used to apply voltage to one of the input
zones on the radio, do the following:
1. Connect the arm (common) of the relay to 12VDC.
2. Connect the N.O. contact of the relay to the input zone. When the relay is activated, voltage will be
applied to the zone, causing the radio to send its message (see Figure 9).

• For UL zone operation, the K3852 must be used with controls that are UL Listed.
• Bell outputs cannot be used as a zone trigger for UL installations.
• All interconnecting wiring between the K3852 and the control unit must be no longer than 3 feet.
– 23 –
Page 24
U
Wiring and Configuring ECP Communication (ECP Options)
The K3852 supports ECP messaging to communicate directly with the control panel. An unprogrammed
radio can be set to communicate on the ECP bus at device address 3 by pressing the tamper switch during
the initial power up period. See “Programming the K3852” for details. Only certain panels support ECP
data communication at this time (i.e., ADEMCO’s VISTA-10SE, VISTA-20SE, Via-30P and
VISTA-128FB). Select this mode of operation with jumper P3. When P3 is in the ECP position, zone 5 and
zone 6 become ECP IN and ECP OUT, respectively. When using ECP, zones 1 through 3 cannot be used.
Zone 4 becomes the arm/disarm “zone,” if this feature is selected.
Connect the K3852 in parallel with keypads and other peripheral devices such as RF receiver, VIP module,
etc., that use ECP. To wire the radio for ECP communication, do the following:
1. Connect terminal 9 on the K3852 to Data Out terminal of the alarm control panel.
2. Connect terminal 10 on the K3852 to the Data In terminal of the alarm control panel.
3. Connect terminal 4 on the K3852 to the Ground terminal of the alarm control panel.
Wire length/gauge limitations are the same for the control panel keypads as they are for the radio. Refer to
the control panel Installation Instructions.
• For UL ECP installations, the K3852 must be connected to a Listed compatible control unit.

Figure 10: Wiring the K3852 for ECP data communication
ECP Status Codes
When the K3852 is configured for ECP mode, it sends status messages to the control for battery, AC
power, tamper and RF failures. The status is displayed on the control’s keypad as “Long Rnge Fail”
followed by a 4-digit code when using Ademco’s low-end control panels (Vista-10SE, Vista-20SE,
Via-30P). These code are listed below, as well as Contact ID codes sent to the central station.

Wiring for Radio Faults
You may program the radio fault output relay (refer to Programming the K3852 section) for either:
FAIL-SAFE mode (UL requirement)
• Answer “Y” to “FLT REL ON (Y/N)”
• Relay always energized [N.C.]
• Relay will change state (and trigger a dialer, if
connected) in the event of power loss.
• Fail-safe mode increases the standby current by about
10mA, which results in lower battery backup time
(about 15%) in the event of power loss.
LOW CURRENT mode
• Answer “N” to “FLT REL ON (Y/N)”
• Relay normally de-energized [N.O.]
• Does not increase standby current
• NOT approved for UL installations.
Run two wires from the K3852’s radio fault terminals 11 and 12 to a zone on the control panel. Refer to the
Figures below for wiring the radio fault relay.
Figure 11. Wiring the K3852 to trip a control panel zone Figure 12. Wiring the K3852 to trip a
during a radio fault (required for UL installations)control panel zone for normally open fault
(not UL approved)
AC Power Connections
Primary power for the K3852 is provided by a wall-mounted 16.5VAC / 40VA transformer ADEMCO PN:
1361 (1361CN in Canada). Use of a transformer with a lower power rating will result in unreliable system
operation.
Connect the AC power wires from the 16.5V 40VA wall transformer to terminals 1 and 2 on the K3852. Do
not plug the transformer into the AC power source until all wiring connections have been made and you are
ready to power up the K3852. Refer to the K3852 Initial Power-Up Sequence section.
Backup Battery Connection
The optional battery backup (ADEMCO 7720BT) can provide over 4 hours of system life in the event of an
AC power failure. When AC power is lost, the K3852 enters a low-power state and the programmable AC
loss message can alert the AlarmNet Control Center (AC loss messages are reported within 10-40 minutes
of actual AC loss). Any alarms that are tripped during this low-power state will wake the system up to
transmit the appropriate message. After a successful transmission, the K3852 will reenter its low-power
state. When the battery reaches 10.5V, a low-battery message is transmitted, which alerts the AlarmNet
Control Center that this may be the radio’s last message. When the battery reaches 8.5V, radio
transmissions are no longer possible and the system shuts down. If AC power is restored before the system
shuts down, an AC Restore message will be sent and the battery will be recharged using the K3852’s builtin battery charger. If AC power is restored after the system has shut down, a power-on reset condition
exists, and the radio will initialize itself as described earlier and the battery will be recharged.
The K3852 performs a battery test under load on a daily basis. During this test, if the battery drops below
10.5V, a low-battery message will be generated to indicate that the battery should be replaced.
To install the battery, snap it into the battery holder with the connector wire towards the lower right. Do not
plug the battery in until all wiring connections have been made and you are ready to power up the K3852.
Refer to K3852 Initial Power-Up Sequence section. When you are ready to power up the radio, plug the
battery connector into the battery jack located on the right-hand side of the K3852 terminal strip.
Lower cover must be in place for the K3852 to enter its lower power state during battery operation.

Section 7. Operation Overview
LED Indications
The K3852 has two sets of LED displays: Radio Status LEDs and a multi-function bar graph.
Radio Status:Green, yellow, and red LEDs, which provide information on pending messages,
successful or unsuccessful message transmission, network connectivity, and
registration status. Refer to Table 6 below.

Bar Graph Indications
Signal Strength:Viewed with the cover removed (refer to Removing the Cover section),
this display consists of one yellow and four green LEDs arranged in a bar graph. It
indicates the signal strength at which the K3852 is receiving the local cell. The display
is intended as an installation aid for determining a suitable mounting location. Refer to
Selecting a Radio Installation Site section for an explanation of its use.
Power-Up:During power-up, the bar graph LEDs are used to monitor radio initialization, and is
read from right to left. Refer to the K3852 Initial Power-Up Sequence section for details.
Registration:The bar graph display also monitors the radio’s registration progress. Refer to
Registering the Radio section for detailed information.
Transmit Error:The bar graph LEDs also indicate failed message transmission error codes by the
number of lit segments. Refer to the Transmitting an Alarm paragraph on the next page
for details.

Normal Operation
With the K3852 installed, programmed, and registered, and after a successful transmission of the Power on
Reset message, the K3852 enters normal operation. Normally, with good cellular coverage and no
messages pending, the yellow status LED will flash in one of two patterns indicating the operating carrier.
• Yellow flashing once per second indicates no alarm messages are pending and that the K3852 is
connected to a cell being operated by the “B” side carrier.
• Yellow flashing twice rapidly, then a pause every second, indicates no alarm messages are pending and
the cell that the K3852 is in contact with is operated by the “A” side carrier.
Refer to Table 6 for all LED patterns
Note that at any point during operation, a solid red LED indicates that contact with the cell has been
lost. The K3852 will automatically attempt to regain contact with the cell. If contact is not regained
before the programmed radio fault time, the radio fault relay will change state, sending a radio fault to
the panel. Refer to Table 6 for all LED patterns.
Transmitting an Alarm
While in normal operation, triggering any zone or reception of a valid ECP message will initiate the
transmission of an alarm. The yellow status LED will light solid, indicating a message pending. The green
LED will flash rapidly 8 times when the alarm message has been successfully transmitted. The yellow LED
will begin to flash rapidly, indicating the K3852 is waiting for a message validation from AlarmNet Control.
This may take several minutes to receive, since the validation is a low priority message. When the K3852
receives the validation from AlarmNet, the yellow LED resumes its normal blinking pattern. If the K3852
does not receive a validation within 90 seconds of a successful transmission, it will retransmit the alarm. The
K3852 will continue to retransmit an unvalidated alarm once every 90 seconds until the message is
validated, or the “old alarm time” has expired. If the message is not validated, the alarm is removed and the
K3852 resumes normal operation. When the zone restores, if zone restoral has been programmed, the
restoration message will be transmitted and the validation will be received with the same LED patterns.
Refer to Table 6 for LED patterns.
If an alarm is not successfully transmitted before the old alarm time expires, the radio fault relay will
go to its programmed fault state.
The red LED will flash 8 times and the yellow LED will remain solid any time a transmission is
unsuccessful. Additionally, the bar graph LEDs will display an error code (refer to the diagram below). The
K3852 will automatically attempt retransmission of the alarm within 10 seconds. The radio will continue
to retransmit until it is successful, unless a radio fault has been generated (the red LED lights solid on).
Refer to Table 6 for LED patterns.

Radio Supervision
The K3852 periodically transmits supervisory and status messages to alert the network that it has
communication integrity. The supervision period (window) is a programmable feature (see Question 5). If
no messages are received by the AlarmNet Control Center during the supervisory window, a
communication failure signal is routed via RF to the appropriate AlarmNet–A or AlarmNet–M equipped
central station.
