Factors Affecting Radio Reception and Antenna Connection
CALIBRATION PRECAUTIONS: If the radio system is not installed and calibrated
properly, the controller may not receive the activation signals. This may cause
the siren to fail and not operate in an emergency, resulting in extensive property
damage or death.
ACTIVATION CODE WARNING: Other local siren sites may have the same
activation code. Take appropriate precautionary measures.
CONNECTION WARNING: All antenna connections must be properly sealed.
The radio network (transmitter, receiver and decoder) is the vital link to proper controller
operation. Consider the following during installation.
• Individually evaluate all controller installations. Contact Federal Signal to discuss
a suitable controller site location, the proper type and location of antenna and
transmission line, and to answer any questions regarding the installation.
• Distance from the transmitter is not necessarily the only factor that determines signal
quality. The effects of terrain and structures can result in weak or variable reception
at a given siren site.
