Your fire alarm systems and phone lines: The truth about their future together


Soon you will have a fire alarm system that is not commu- nicating or supervised with your central station as there is no measurable voltage going through the fiber. The solution is very simple. Install a radio communicator that is listed as a dual path communicator. To meet our customer’s needs, BH Secu- rity started building our own private radio network utilizing AES IntelliNet Fire Radios. These radios utilize a star pat- tern which retransmits signals from one radio to at minimum two other radios in our net-

work until they reach the radio receiver at our office as well as at the central station. This is even more redundancy than is required by NFPA. The signals are normally at the central station being processed by an operator within 3 to 5 seconds after the fire alarm system has activated. In the three years since we started installing ra- dios in lieu of utilizing phone lines, we have a network of just under 300 radios. Not only have we been able to give our customers a much more reliable means of com- munications, we have elimi- nated the nuisance calls about down phone lines and at the same time have saved our customers approx. $500.00 per year.

The digital dialer was developed and with enhance- ments met code as the primary means of communications for fire alarm systems. Supervi- sion was accomplished by con- tinually measuring the phone line voltage generated by the phone company central office. With a digital dialer you are required to have at least one

dedicated phone number and a second line that could be shared with a house phone for back up. As property owners it was not likely that you had a second line that could be shared so you are more than likely still paying for two dedi- cated lines. Now the issue is that most of our phone carriers are rapidly moving away from traditional copper lines and replacing them with fiber VOIP (voice over IP) which is not accept- able as the primary means of communications for a com- mercial fire alarm system.
