JTECH Communications Inc. SERVALERT200 Manuel D’Utilisation

 

 
The SmartAlert Transmitter is wired directly to a communications port on your 
host device.  This may be a Personal Computer or other electronic device and to 
any analog phone jack on your telephone system.  The first consideration in 
installation is regarding the placement of the SmartAlert Transmitter.  It should 
be as high as possible and must be located within the length of the 
communications cable.  RS232 cable length maximum is 50 feet.  The next 
consideration involves safety.  Be sure the unit is securely mounted and safe 
from liquids, extreme heat, and possible physical damage. 
 
The antenna must be vertical.  As with any transmitting unit, pay close 
attention to obstructions when locating antenna.  Wall, pipes, ducts, mirrored 
glass, or other similar barriers may weaken or misdirect transmitted signals.  
Certain materials and construction, especially metal, have the potential to 
partially or completely block the signal.  Also remember that the SmartAlert 
Transmitter requires an 110V outlet for power.  
 
Follow the directions below for the SmartAlert model 8205 RS232 with 
Telephone Interface 
1.  Attach the antenna to the BNC antenna port marked A1.  
2.  Connect one end of the RJ-11 phone cord to the phone jack marked J2 on 

the front of the unit and the other to an available phone jack line in your 
telephone system.  The Phone Interface requires an analog phone jack; the 
Phone Interface must be able to hear the tones from a push button 
telephone. Please refer to the section titled ‘Telephone Interconnect 
Specifications’ for additional help in determining the type of phone line.  
Continue with step two below.
