What is a monitored system?

Alarm systems which transmit a signal to a remote manned location are said to be monitored.

Our Monitoring Facility

National Home Security's monitoring facility meets the most demaning standards set by Underwriter's Laboratories and qualifies customers for the highest insurance ratings. 

What are the types of monitored alarm systems?

Standard or One-Way
   
The alarm system transmits a one-way electronic signal, usually via telephone lines, to the monitoring facility which in turn calls authorities and notifies appropriate individuals. Ninety percent of the alarm systems are of this type.
Two-Way Voice
   
Once the alarm signal is received by the monitoring facility, a trained operator is able to listen-in and speak over special microphone/speakers to verify the type of emergency before authorities are called.
Cellular Backup
   
Alarm signal is transmitted over cellular telephone network should regular telephone alarm transmission be cut or out of service.

Standard or One-Way Systems
   
Once the main system siren sounds, the alarm system seizes the telephone line and transmits an electronic signal to the monitoring facility. This signal is coded to identify the customer and the type of alarm. The appropriate authorities, usually police or fire, are called at once, the badge number of the dispatcher is recorded, then individual(s) on the customer's call list are notified of the alarm. All events are date/time stamped.
Two-Way Voice
The alarm system dials up the monitoring facility like a standard system, except the two-way voice operator is able to remotely speak and listen over special microphone/speakers. The operator asks what the problem is and for a password. The operator then takes appropriate action based on the response. If the operator fails to hear anything or in told an incorrect password, the authorities are called. The siren automatically stops while the operator in connected to the alarm system.

What should you do in case of a false alarm?

Standard or One-Way Systems
 
 
Immediately disarm your system by slowing entering your code. This while stop the siren and send a "cancellation" signal to our monitoring facility to disregard the alarm. If the siren goes longer than 30 seconds, we may have already notified authorities. In either case, you should call the monitoring facility, identifying yourself with your account number and passcode, to verify the cancellation was received or to have our monitoring facility try to recall the authorities.
    Note: During an alarm, the security system is designed to seize the telephone line for a secure transmission of the alarm signal. This may result in a temporary loss of dial tone. After a brief period, the security system releases the telephone line and your dial tone returns.
Two-Way Voice
   
Immediately disarm your system by slowly entering your code. However for most two-way systems, the operator still comes over the microphone/speakers to verify the status and ask for a password.

How do I test my system?

    Before you test your system, please call the monitoring facility and tell them you wish to test. You need to identify yourself with account number and passcode. The best way to test is to put the system into full alarm and let the siren sound for at least 30 seconds. Then disarm and call the monitoring facility to insure the alarm signal is received. If signal is not received, please call our office to determine the problem.
    We urge you to test your system frequently, especially any time work or changes are done to your telephone service or telephones. There is no extra charge for testing.

How do I make changes to my call list?

    Simply call the monitoring facility and the operator is happy to assist you. You may also call our office as well.
