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, 470-
512 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.
