About the 7845CZ
The 7845CZ 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 7845CZ 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 7845CZ 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 7845CZ 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.

Antenna
An ADEMCO cellular antenna is included (part number K4193). The 7825-OC Antenna is for
optional outdoor use.
Power
The unit is powered directly from a control panel's 12VDC source, or an optional 7720V2TR
12VDC power pack. The 7845CZ is not dependent on the battery to support transmissions,
and will draw up to 400mA from the DC source for up to 3 seconds at a time.
A programmable feature allows the installer to limit input current to 100mA when the unit
is powered from a control panel that cannot provide the 400mA peak transmit current. In
this mode, the radio is completely dependent on the backup battery to transmit, and will not
transmit if a low battery condition exists.
The battery for backup adds over 4 hours of additional system life during DC loss. ADEMCO
PN: K4362. 6 Volt, 0.5Ah.

Selecting a Radio Installation Site
BEFORE DRILLING ANY HOLES FOR MOUNTING:
•
CHECK FOR MICROBURST!
Be sure that MicroBurst is available
in the area in which this unit is to be installed.
•
CHECK SIGNAL STRENGTH!
Select a location where the signal
strength level is consistently better than 3 bars or -94dBm as
measured with the 7720P.
•
CHECK ABILITY TO TRANSMIT!
Be sure that the 7845CZ can
successfully transmit in the location selected. The red status LED
should NOT be blinking after each transmission attempt.
REMEMBER, IT’S ALL ABOUT COVERAGE!
When selecting a mounting location, do not mount this unit in an area where the general public
could reasonably be within 20cm (8 inches) of the antenna.
1. Remove the cover and connect TB1 V+ and GND terminals to the control panel's +12VDC
auxiliary power output.
2. Select a likely location by monitoring the signal strength bar graph (see
Figure 2.
Signal Strength Bar Graph Displays
). Refer to the “Using an Unregistered 7845CZ
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 3 bars or –94dBm as
measured with the 7720P. The 7845CZ can function properly with the signal strength
level as low as one-half bar (yellow blinking), but this is an indication of marginal
coverage.
NOTE:
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.
NOTE:
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.
Table 2. Minimum Distances from Electrical Equipment
EQUIPMENT DISTANCE
PIR 10 ft.
FM radio or TV antenna 25 ft.
Other devices 10 ft. minimum
The 7845CZ is designed to be mounted on a vertical surface (wall), with the included antenna
pointing up. When selecting a mounting site, maintain distances from various types of
electrical equipment as listed in
Table 2
. Additionally, observe the maximum wire run
lengths (refer to the “Wiring and Mounting” paragraph
in given mode of operation section).
The 7845CZ is intended for indoor installation only. Mounting outdoors will cause system failure
and may present a shock hazard.
Section 4: Installation and Setup

Using an Unregistered 7845CZ as an Installation Tool
An unregistered 7845CZ will display signal strength once
the initial power-on sequence is complete.
Use the guide on the right when selecting an installation
site.
Select an installation site where the RSSI is between 3 –
5 bars.

Initial Power-Up Sequence
Before connecting power, check that the following have been completed:
•
Terminal block TB1 V+ and GND terminals are connected to the control panel’s auxiliary
power output: 12VDC nominal.
•
Antenna installed.
Apply power. Initially, all 7845CZ programming options are set to the factory default
settings.
Upon applying power, the 7845CZ enters a power-on reset state, indicated by the RSSI,
mode, and status display LEDs lighting in a “chaser” sequence. After this power-up
sequence, the radio status LEDs display: green lit, yellow blinking, and red lit.
This indicates the 7845CZ is functioning but not yet initialized. The 7845CZ then begins its
initialization sequence. During this process, the 7845CZ 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 4): The yellow
LED remains unlit and the green LED at the extreme right of the display begins to blink.
This green LED then lights (after a short period of time), and the next green LED to the left
begins to blink. When this LED lights, the next green LED begins to blink, and so on, until
all 4 green LEDs are lit. This countdown event may take up to 10 minutes to complete.
Once this sequence has been completed, the RSSI display begins to function as a signal
strength indicator as described in the “Selecting a Radio Installation Site” paragraph in this
section. The radio is now in normal, unprogrammed and unregistered operation. If radio
setup and self-test fails, LED 5 blinks continuously and no further progress is made. If
MicroBurst coverage is not found on either the A or the B side, the 7845CZ repeats Table 3,
steps 2 and 3. These steps are repeated until MicroBurst is found.

Testing the Installation
Using an Unregistered 7845CZ to Test the Installation
An unregistered 7845CZ can send three types of test messages: unvalidated, validated, and
test registration. Refer to the tests below.
Unvalidated Test Message
Use this to test the path from the 7845CZ 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 7845CZ is receiving this cell.
Read the RSSI display from left to right: If the
yellow and the next two green LEDs are lit, the
display is read as “three bars.” If the yellow and
the next two green LEDs are lit 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. See the Full-Scale RSSI
Display diagram in Figure 2.

message transmission to local cell:

message transmission:
Validated Test Message
Use this to test the path from the 7845CZ to
AlarmNet and back to the 7845CZ.
DOUBLE-click the tamper switch to send a test
message to AlarmNet with a validation request.
The yellow radio status LED blinks rapidly while
waiting for validation. Validation is a low-priority
receipt from AlarmNet to the 7845CZ and may take
several minutes to receive. If AlarmNet does not
validate a message within 90 seconds, the 7845CZ
retransmits the test message and waits for
validation.

message transmission to AlarmNet

NOTE: When a good test message is sent from the 7845CZ, it can be assumed with a high
degree of certainty that it reached AlarmNet without waiting for validation. Numerous
transmission failures (indicated by the red LED blinking rapidly) indicate that the location
chosen might be preventing the 7845CZ from transmitting well; the unit should be relocated.
To cancel any test message, single-click the tamper switch.
Test Registration
Use this to test the path from the 7845CZ to AlarmNet, then to the central station, and back
to the 7845CZ. This confirms the radio’s programming and routing across the AlarmNet
network without actually registering it. Use the [T] command to initiate test registration.
Refer to Section 6: Registration for a detailed description of this feature.
NOTE: Programming Options 2, 3, and 4 must be programmed to use this feature.

Mounting and Wiring
BEFORE DRILLING ANY HOLES FOR MOUNTING, DID YOU:
•
CHECK FOR MICROBURST?
•
CHECK SIGNAL STRENGTH?
•
CHECK ABILITY TO TRANSMIT?
REMEMBER, IT’S ALL ABOUT COVERAGE!
Mounting
Install the included antenna by screwing it onto the connector at the top of the 7845CZ. The
final mounting site should be chosen so that:
•
wire lengths do not exceed the maximum wire lengths as specified in Table 6
•
minimum distance to other electrical devices is maintained
•
minimum signal strength level is observed
•
there is access to the 7720P programming port and tamper switch
•
all LED displays can be observed
•
antenna is free from any interference.
Once the 7845CZ 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 3. 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.
NOTE: The third mounting hole located behind the antenna is not shown in Figure 3.
