System Overview
Introduction
Congratulations on your purchase of Honeywell's 7845GSM/7845GSMCN Digital Cellular
Communicator (henceforth referred to as 7845GSM). It represents the latest and most
innovative communication technology for the security industry and uses the most
sophisticated encryption to ensure the highest level of security for your customer.
In addition to alarm reporting, the 7845GSM provides upload/downloading capability of
Honeywell's control panel data via the AlarmNet-G network, using GSM (Global System for
Mobile) technology.
The 7845GSM module requires an AlarmNet–I account. For new installations, please obtain the
account information from the central station prior to programming this module. For replacement
installations, the AlarmNet-I account is created automatically when the module is registered (based on
the existing "C Series" account).
♦ Specifications
General Information
Honeywell's 7845GSM Cellular Communicator transmits signals to the AlarmNet-G network
(GSM cellular network, which uses GPRS to complete these transmissions) and forwards
them to your central station. If your current Central Station is capable of receiving signals
from AlarmNet central stations, they are capable of receiving signals from the 7845GSM.
If the GPRS network is unavailable, the 7845GSM will attempt to send the transmission via
SMS (Short Message Service).
System Features
Basic features of the 7845GSM include:
• Quick connection to compatible Honeywell series control panels
• Simple programming using a 7720P programming tool
• Reports fire, burg, and status messages via wireless network
• Allows uploading and downloading of control panel data via the wireless network.
Modes of Operation
The 7845GSM provides four modes of operation so it can be used with various types of
control panels, as summarized below:
ECP Mode
• This mode is for use with Honeywell controls that support LRR-ECP communication
• The module connects to the control’s keypad terminals and provides 2-way communication
with the control using ECP messaging

7845GSM/7845GSMCN Installation and Setup Guide
• The control treats the module as a Long Range Radio (LRR) device, so program the control
accordingly, including setting the module’s proper LRR device address
• Reports are sent in Contact ID format
• The module also supports two hardwire zone trigger inputs (zones 6 and 7)
Zone Trigger Mode
• This mode is for use with controls that do not support LRR-ECP communication nor 4204
Relay Modules
• The module provides six input zones
• Each zone can be configured for +V, -V, or EOLR triggering
• Each zone can be programmed for inverted operation, delayed reporting, and restoral
reporting
• Zone 1 input can distinguish between pulsed and steady signals and report fire or
burglary alarms respectively
• Zone 1 can also be programmed to report Lynx panic (if used with Lynx control)
• Reports are sent in ADEMCO High-Speed format
4204 Mode and Two-4204 Mode
• This mode is for use with Honeywell controls that do not support LRR-ECP
communication, but that do support 4204 Relay Modules
• The module connects to the control’s keypad terminals
• The control treats the module as 4204 Relay Module(s), so program the control
accordingly, including setting the module’s proper 4204 device address
• 4204 mode provides up to four zone inputs, plus two optional trigger zones, depending on
options programmed
• Two-4204 mode provides up to eight zone inputs, depending on options programmed
• Each 4204 zone can be programmed for delayed reporting and restoral reporting
• Reports are sent in ADEMCO High-Speed format

Module Supervision Features
The 7845GSM provides the following types of supervision and module fault detection:
• Network communication failure
supervisory message from the module within a specified time (“Supervision” option, 24
hours, 30 days, or none), AlarmNet notifies the central station of a communication failure.
• Communication path failure
failure, the control panel can be notified of a trouble condition with the module after a
specified time has elapsed (“GSM Flt Time” option, 00-99 minutes).
• Fault output
If used, the fault relay will trip when the following conditions occur: tamper*, power loss*,
low battery*, battery charger fault*, loss of network connectivity*, the device is not
registered and the device is remotely disabled by AlarmNet.
*Alarm reporting for the noted condition must be enabled for it to trigger the fault relay.
• Primary power loss and low battery conditions (“Pwr Loss Rpt,” “Low Bat Rpt” options).
• Cover tamper condition (“Tamper Rpt” option).

4. Locate the case back over the mounting surface such that the opening in the case back
is aligned with the wire/cable access opening (in the mounting surface) while passing
the wires/cable through the opening in the case back, or through the removable
knockouts located on the bottom of the back cover.
5. Secure the case back to the mounting surface using four screws (supplied).
6. When all wiring is completed, attach the case front of the 7845GSM to the case back.
Attach the top of the 7845GSM first then press the bottom section inward until it snaps
into place. Secure bottom using cover securing screw (supplied) as shown below,
(required for UL installations).
Unshielded, 22 AWG cable is recommended for 7845GSM power/data wires.
Wiring for ECP, 4204 and Two-4204 Modes
Most Honeywell ADEMCO control panels support LRR-ECP data communication, (e.g.,
VISTA-10P, VISTA-15P, VISTA-20P, LynxR-I, VISTA-128BP and VISTA-128FBP). However,
there are some panels that do not. Check the Installation and Setup Guide for the control
panel you are using to see if it supports ECP communication.
Connect the 7845GSM to a compatible Honeywell VISTA control panel's ECP terminals, in
parallel with keypads and other peripheral devices such as RF receiver, VIP module, etc.
Wire length/gauge limitations are the same for the module as they are for keypads and other
peripheral devices. To wire the module for ECP or 4204 modes, see Figure 2 and make the
following connections:

•The module transmits a low-battery message (programmable) when the battery
reaches 5.7V ±5%, indicating subsequent message may not be transmitted.
•The system shuts down when the battery reaches 5.1V, and radio transmissions are
no longer possible.
•If system power is restored before the module shuts down, a power restore message is
sent within 1-3 hours after power is restored, and the battery is recharged using the
7845GSM’s built-in battery charger. If system power is restored after the 7845GSM
has shut down, a power-on reset condition exists, the module initializes itself and the
battery will recharge.
Install the battery as follows, and refer to the Summary of Connections diagram at the end of
this document.
1. Place the battery inside the case back.
2. Snap the right side of the battery clip onto the inside of the case back and secure the
left side with the screw provided.
1. Do not plug the battery in until after you have powered-up the 7845GSM.
2. If using a LynxR-I, do not connect the module's backup battery. The LynxR-I backup
battery will supply backup power in the event of a power outage.
Initial Power-Up Sequence
Before connecting power, check that the following have been completed:
1. If using ECP Mode, terminal block TB1 V+ and GND terminals are connected to the
control panel’s auxiliary power output: 12VDC nominal.
2. Plug in the transformer (or other main power source). Initially, all 7845GSM
programming options are set to the factory default settings.
3. Connect the red and black battery cables to the battery terminals. Connect battery cable
to connector J1.
4. Power up the control panel.
