SC3100 Radio Communicator Location 
The SC3100 Radio Communicator is designed to be installed inside of the host alarm panel. If the size of the 
host alarm panel will not permit mounting the SC3100 inside or for special SC3100 configurations, then the 
SC3100 enclosure can be mounted directly to a vertical surface, like a wall, using the keyhole mounting holes 
provided on the rear of the SC3100 enclosure. This type of mounting will also require the use of an L bracket to 
mount the factory supplied antenna. This L bracket is provided with all SC3100 units sold by Bosch Security 
Systems. The L antenna mount bracket is Bosch Security Systems part number #80072-101. 
 
The SC3100 is not environmentally sealed.  Do not mount the SC3100 where it can be exposed to 
the elements. 
If the antenna is mounted directly on the exterior of the host alarm panel enclosure, the alarm panel should be 
mounted on the inside of an exterior wall, for optimum radio transmission and reception. However, it should not 
be mounted in close proximity to: 
• 
A cable bundle and/or wiring harness that is routed vertically and in close proximity to the SAFECOM 
antenna. 
• 
A computer, PA, entertainment, or sound system. 
The following should be considered when determining the location for mounting the SC3100: 
• 
Space restrictions of the host alarm panel. 
• 
Distance to the antenna from the SC3100 Radio Communicator. 
• 
Antenna proximity to a cable bundle and/or wiring harness. 
• 
Antenna proximity to computer, PA, entertainment, or sound systems. 
• 
Easy access by a service technician. 
3.6 Antenna 
Location 
Improper antenna location is the single most common problem found in SAFECOM installations. The only way to 
properly determine the best location for the SAFECOM antenna installation is to use the SAFECOM IT1500 
Tester. 
IMPORTANT
 
The SAFECOM IT1500 Tester must have a minimum of 9dB of attenuation installed between the 
Tester and the Tester’s antenna.  If the Tester, along with the 9dB attenuator does not produce a 
minimum of 10 “pass” indications following the tests, then the SAFECOM SC3100 Radio 
Communicator cannot be installed in this location. Refer to the SC9000 Operations Manual section 
titled “Using the IT1500 Tester” for more information on finding another location within this 
building and testing possible antenna locations.  For information on ordering an external 
attenuator for your SAFECOM IT1500 Tester, contact a SAFECOM Applications Engineer at (800) 
538-5807. 
If the SC3100 Radio Communicator is installed inside of a host alarm panel, then the antenna must be mounted 
externally to the host alarm panel. Do not mount the antenna inside of the host alarm panel enclosure. 
A successful RF communications link between the SC3100 and the Central Station SC9000 computer may be 
subject to external interference. Several environmental effects must be considered when determining the proper 
location for mounting the SC3100 antenna. 
Transmission and receipt of radio signals may be blocked by metal, mountains, hills, foliage and other natural 
and man-made obstructions. 
Some extent of radio signal degradation may be seasonal. Weather may significantly degrade reception ranges 
due to propagation from temperature layers and reflection from the moisture content in the atmosphere. 
Transmission and reception ranges may be reduced by dense foliage on trees and shrubs, or by snow. This 
degradation is normally experienced during the spring and summer months when the presence of leaves tends 
to block the signal path. 
For optimum transmission and reception of radio signals, position the antenna as high as is possible within the 
structure. Mounting the antenna on an elevated structure will enhance the line-of-sight Tx/Rx range and 
communications link effectiveness. The antenna should NOT normally be mounted inside metal buildings or 
enclosures. The proper antenna location is site specific for each installation.
