Communication

A Key Component Of Your Alarm System

In an alarm condition, the control panel in your alarm system transmits an alarm signal to UL & FM Approved Central Station.  Once the Central Station receives the signal our operators quickly notify the appropriate authorities of the emergency and calls the call list you provide.  Therefore, a dependable communication line is a critical component of any alarm system.

No matter how many locks, sensors or detectors you have, your alarm system must be able to communicate with the central station in order to provide protection.  If the monitoring center does not receive a signal, no one will be aware of the potential danger or threat to your safety and no one will contact the police, the fire department or your contact list – help will not be on the way.

Allied Alarm Services, Inc.  offers three options for communicating signals to the Monitoring Center:  traditional phone lines, cellular and network communications.  Each option has its advantages and disadvantages.  Our trained consultants can help you select the option or combination of options best suited for your situation.

Traditional Phone Lines.  Traditionally alarm systems have communicated over the POTS (plain old telephone system) network.  Until recently they have been the most reliable and cost effective alternative.  However, this can be a challenge as more and more options for telephone service become available; many industry experts expect traditional phone lines to be obsolete in the next five years. In addition, burglars have realized how easy it is to cut your phone lines and disable your alarm system.

With traditional phone lines your system will be programmed to send an automatic test signal each week to ensure the communication lines are in proper working order.

Cellular.   Where available, cellular communication provides a very reliable communication path.  In critical installation where you need to eliminate the risk of cut phone lines or power outages that affect network connections, cellular is the solution.  With cellular communication your system will be programmed to send an automatic test signal each week to ensure the communication lines are in proper working order.  *Please note that this cellular service is not available in all locations.

Network. Using  your home computer network and internet connection your system can be programmed to send an automatic test signal to the monitoring center every four (4) hours to ensure the communication lines are in proper working order.   You will need to provide a local IP address, subnet mask and gateway.  In addition, port 2001 in your firewall will need to be opened bi-directionally.

 

A Note About Non-Traditional Phone Lines …. Many homeowner’s and businesses have converted to VoIP or digital phone service to save money.  Unfortunately, this can leave your alarm system vulnerable to failure.  Power outages and internet service interruptions are common.  VoIP is still an emerging technology and is not currently regulated by the FCC.  Consequently, the service provided is not standardized among providers.  Even within the same provider’s network, the compression ratio or bandwidth may change or be modified based on network capacity.  An alarm system that communicates effectively when VoIP is first installed may suddenly fail.  Therefore, Allied Alarm Service, Inc. does not recommend communicating over VoIP phone lines.
