SAFECOM is a long range telemetry communications system for monitoring life safety security alarm panels
which are remotely located at a customer site. The SAFECOM system utilizes specially designed telemetry
transmitters and receivers to provide a secure and reliable radio communications link between remote alarm
panels and a Central Monitoring Station. The information provided to the Central Monitoring Station allows
security personnel or local authorities to respond immediately and appropriately to all alarm events detected at
the customer site (see the following figure).

1.1 SAFECOM Communications Paths
The SC9000 Receiver acts as the nerve center of the SAFECOM Base Station. The SC9000 Receiver uses a
personal computer to operate the ST1000 Receiver Software and provide radiocommunications with remote
Radio Communicators via the RF2000 Radio Modem.
A Radio Communicator is a SAFECOM Communications Panel which is located at a customer site; commercial
or residential. The SC9000 SAFECOM computer can supervise, monitor, and control up to 2,500 Radio
Communicators through two-way telemetry radio communications.
The receipt of each message or poll that is transmitted is validated by the receiving site; SC9000 computer or
Radio Communicator. The receiving site will then transmit an acknowledge message in response.
Supervisory polling is performed by the SC9000 computer for each Radio Communicator to verify two-way
telemetry radio communications and the operational condition of the Radio Communicator. The supervisory
polling interval is individually programmable for each Radio Communicator in the SC9000 computer account
base.
The SAFECOM radios can be configured to transmit (TX) and receive (RX) on a single frequency pair directly to
the Central Station. When the SAFECOM system is set up for Direct Mode, the SC9000 computer communicates
directly with the Radio Communicators in the field. No repeater is used for this type of SAFECOM system
(usually found in smaller proprietary systems like those found on a military base, university, or
factory/commercial plant).
The SAFECOM radios can also be configured to transmit and receive on a frequency pair to a repeater located
on a mountain, tower, or high building in the desired coverage area. When the SAFECOM system is set up for
repeater mode, the SC9000 computer communicates with the Radio Communicators through a, UL Listed,
SAFECOM SC801 or SC802 Data Repeater, or a commercial grade voice repeater that has been configured
with a SAFECOM DP1000PWA Controller Board. The SC801/SC802 or equivalent repeater is normally installed
at a Commercial Repeater Site.
The use of a SAFECOM type or equivalent repeater significantly increases the coverage area (range). Radio
area coverage and reception ranges are also dependent on the extent of a number of environmental effects, e.g.,
propagation losses due to atmospheric conditions, and the proximity of the radio transmission and reception
paths to dense foliage and metal structures.
The majority of SAFECOM Radio Communicators are ordered to TX and RX in the 450-470 MHz UHF frequency
range. Other frequency bands currently supported by Bosch Security Systems include the 403-430 MHz, 470512 MHz, 136-174 MHz VHF range and the 900 MHz band. Additional frequency ranges are available upon
request. The SC9000 computer can communicate with all Radio Communicators assigned to that specific
SAFECOM network on a single RF “channel” through one SAFECOM RF2000 Radio Modem. A single RF
channel is one radio frequency pair for either direct OR repeater communications.
With the installation of a SAFECOM 4 or 8 port Expander Board, the SC9000 computer can communicate on 1 to
8 independent and addressable RF channels. Each RF channel communicates through a separate RF2000
Radio Modem. The addition of RF channels can be used to achieve backup redundancy in an area, or greater
RF coverage range.
The SAFECOM IT1500 Installation Tester allows the installer to test for a standardized signal level from the
remote radio site to the SC9000 computer and back, full two-way. Through this testing by a sales or service
representative, a two-way communications link can be confirmed between a Radio Communicator and the
Central Station Receiver PRIOR to the installation of a SAFECOM system.
1.2 Overview of SAFECOM Radio Communicators
Bosch Security Systems manufactures the following SAFECOM Radio Communicators:
• SC4000, Full Data Transfer, Eight Zones, Four Outputs, Radio Communicator
− UL Listed
− Radio
− Full data transfer of all alarm panel signals
− Eight zones on board for Open/Closure/Voltage/Bell Out/Ground
1.3 SC3100, Full Data Transfer, Radio Communicator
The SC3100 Radio Communicator is a derivative of the capabilities and features found on the SAFECOM
SC4000. The SC3100 and the SC4000 share the same two-way communications characteristics and receivingand-sending functions of host alarm panel signals. However, the SC3100 is a non-UL Listed device and is not
configured with inputs or output relays.
The SC3100 is normally configured as a stand-alone device for interface with the customer's existing alarm
panel. It is located at a customer site; commercial or residential. The smaller physical dimensions of the SC3100
permits installation inside of many existing alarm panels. The antenna can be mounted directly on the alarm
panel enclosure, or remotely positioned for optimum radio reception and transmission.
The SC3100 is normally installed to Intercept all of the alarm panel signals from the host alarm panel (also
known as a dialer). The dialer message is then digitally encoded and sent to the Central Station SAFECOM
SC9000 computer via the SAFECOM network. When SAFECOM is installed, it is the primary means of alarm
panel communication (the phone line serves as the backup route). The SC3100 is capable of interfacing with
most alarm panels that use industry standard pulse formats (3+1, 4+2, FBI Superfast, Radionics Slow, etc.) or
Dual Tone Multiple Frequency, DTMF (ADEMCO Contact ID, ADEMCO High Speed, or ADEMCO 4+2 Express),
or SIA-R, or Radionics Modem and Modem IIe, or BFSK formats.
The SC3100 can be thought of as “a digital receiver in a box”, in that it has the ability to receive the signals from
the host alarm panel, and then generate an ACK and kissoff to the alarm panel, while sending the signal to the
Central Station SC9000 computer. The SC3100 sends all the necessary (ACK) tones to the host alarm panel in
response to the Dialer seizing the phone line. These ACK tones can be programmed at the Central Station
SAFECOM Computer to short and long durations, frequencies of 1400 or 2300 Hz, as well as low/high (Contact
ID) and the Bosch Security Systems D6500 Modem ACK. The SC3100 has the ability to emulate the following
digital receivers: ADEMCO 685, Bosch Security Systems D6500, Silent Knight, ADCOR, Veritech, Morse, and
ITI. In addition, the SC3100 can be programmed at the Central Station to send a 440 Hz tone to the Dialer to
simulate dial tone. This tone comes in two bursts lasting one second each, and is usually enough to satisfy alarm
panels that “sniff” the phone line for line fail.
The host alarm panel signals are sent to the Central Station SC9000 computer. Then, the signals are displayed
on the SC9000 computer and transferred to the Central Station's Automation Software (BOLD, SIS, SIMS, DICE,
MAS, or most industry standard software package). Primary routing of the digital alarm messages is conducted
along the SAFECOM network that exists between a SC3100 in the field and the Central Station SC9000
Receiver. The primary routing then moves the message to an automation software system.
The SAFECOM SC9000 computer can monitor all of the unique alarm panel signals from each SC3100. The
SC3100 functions strictly in a supervisory capacity when interfaced with an existing alarm system. The SC3100
is an intercept/delivery system which is designed for easy installation and interface with any alarm system. The
alarm panel dialer cable is simply connected to the SC3100 phone jack “DIALER” connector and the house
phone cable from the RJ31X jack, to the SC3100 RJ31X connector.
No modifications to the existing alarm system are required. The normal operation of the existing alarm panel and
security system is not affected in any way. The existing detectors and initiating circuits still report the status of
their circuits directly to the host alarm panel. When the host alarm panel goes to send a signal, it no longer uses
the phone line. The SAFECOM network is used to send all signals that will continue to be received at the Central
Station regardless of the phone line’s status. The house phones will normally not be interrupted by the alarm
panel.
The SC3100 requires an 11 - 15 VDC (12 VDC), 350 mA, power source. This 12 VDC power source is normally
provided by the auxiliary power terminal of the host alarm panel. However, an 11 -15 VDC auxiliary power supply
or external battery is an acceptable power source for the SC3100.
The SC3100 is configured with a 12VDC internal gel cell battery. This internal battery provides all of the
necessary peak current (ampere) requirements when the SAFECOM Radio Transceiver is transmitting (TX) and
receiving (RX). The Battery is mounted inside of the SC3100 Radio Communicator and is accessible by
removing the SC3100 cover and internal battery plate.
Each SC3100 is configured with a Fallback life safety feature. The Fallback mode of SAFECOM communications
ensures that all alarm event messages sent by the host alarm panel will be routed to the Central Station in case
of a SC3100 or SAFECOM network failure. It also provides the ability to perform alarm panel programming and
downloading via the telephone line.
Alarm panel signals are normally routed to the Central Station by SAFECOM radio communications as the
primary mode of transportation. In the event that the SC3100 cannot send the Dialer message via the
SAFECOM network because of some type of failure, the message is automatically routed to the backup phone
line and on to a digital receiver at the Central Monitoring Station (Fallback Mode).
